How to Upgrade your Cleanroom

by Evenbound - Hunter | Aug 6, 2020 | Cleanroom Design, Cleanrooms

As Greek philosopher Heroclitus said, “There is nothing permanent except change.” While the conditions in your cleanroom are designed to stay the same, your work rarely does. If your project needs are evolving, you might find yourself needing to meet new cleanroom classification requirements. Even a seemingly small jump to a more stringent ISO Class can be a big change for your facility. How do you make the leap? Let’s work through what upgrading your cleanroom will look like, and how to start the process.

Upgrading Your Cleanroom Classification?

Start Here.

If you have to move to a more stringent qualification, the first thing you have to do is take a hard look at your cleanroom classification. Start with your classification as it stands and look at the specific areas you need to adjust to achieve the next level of cleanliness. To do that, we have to break down what’s in a classification. While there’s much more involved than just these three elements, the main differences between classifications are defined by:

Allowed particles (by number and size)
Air changes per hour (or airflow velocity)
Percentage of ceiling coverage of FFUs (filter fan units)

When upgrading your cleanroom, you’ll need to make changes to address these three areas in order to make your cleanroom more clean. In addition to ISO standards, your cleanroom upgrade will also reflect necessary changes specific to your new project or scope of work. Consider your new application or purpose and what upgrades will ensure success in your future endeavors. This could include more control over temperature and humidity, more space for equipment, cabinetry and other storage, cleanroom furniture, lighting, ESD-safe materials, or other specialized features.

Redesigning Your Cleanroom

Whether you’re upgrading your cleanroom to meet a new classification, to match a new purpose, or both, there are several factors you should consider when redesigning your space. Your cleanroom upgrade encompasses the layout and structure of your space, your cleanroom’s systems, and how to maintain your new classification once reached.

Reconfiguring Your Cleanroom Layout

When redesigning your cleanroom layout, you can easily rearrange modular panels to create the new space and shape that works for your new project. Add more panels for a larger cleanroom, or remove and store extras for a more controlled, condensed space. Your upgraded cleanroom may require more space for additional personnel, large equipment, or room to move carts and transport products, so be sure to factor these potential needs into your cleanroom redesign.

If you’re upgrading your cleanroom to a more stringent classification, or your project parameters are changing significantly, you may need to choose a different structure altogether. Consider these three types of cleanrooms for your redesigned facility:

HardWall Cleanrooms: Offering increased security and the highest possible control, HardWall cleanrooms are able to meet the strictest classification standards effortlessly.
SoftWall Cleanrooms: The most flexible cleanroom type, SoftWalls are easy to expand, reconfigure and fit in small spaces. They’re an affordable modular option with room to grow.
RigidWall Cleanrooms: With less flexibility than HardWalls but more stability than SoftWalls, RigidWall cleanrooms are a minimalist middle ground made of solid clear panels — great for showing off your operations to investors.

Upgrading Cleanroom HVAC System

Upgrading your cleanroom will likely also require upgrading the systems that support it. You may be able to update your existing cleanroom HVAC system or add a dedicated system if your new classification requires more control over temperature and humidity. A powerful and reliable HVAC system does more than just keep your employees comfortable. It also helps to maintain a stable atmosphere for any sensitive hardware or substances you work with, and prevents machinery from overheating.

Humidity control can help avoid potential problems that come with too much moisture such as condensation and contamination, which could impact productivity by extending drying time or causing products or processes to fail. A cleanroom HVAC system that is in tune with your project and facility’s needs will keep your cleanroom clean and consistent.

Meeting New Cleanroom Filtration Requirements

Your cleanroom classification will specify your allowed particle count, as well as the minimum air changes needed to clean the air effectively. When upgrading your cleanroom, you will likely need to increase your air change rate and capture more and smaller particles. You can achieve this by adding more fan filter units to increase your percentage of ceiling coverage. This is also a good time to check and/or replace HEPA filters to make sure they are effectively removing particles from the air.

Additionally, rearranging your layout or furniture might require the implementation of a new airflow pattern. Furniture or equipment can block filters and interrupt the flow of air, creating pockets of turbulent air or spaces where contaminants could be trapped. To find the best airflow pattern that works with your upgraded cleanroom, work with a cleanroom design expert. They can use computational fluid dynamics to model your cleanroom airflow pattern and make decisions about layout that will improve air change efficiency and support the healthy life of your HEPA filters.

Proper airflow with effective filtration will ensure you are removing particles consistently and reaching appropriate levels for your new classification. Once it reaches that level of clean, all you have to do is keep it there.

Maintaining Your Cleanroom Classification

Once you’ve upgraded your cleanroom to its new classification, congratulations! Now you’re done, right? Unfortunately, reaching new requirements is only half of the battle. Most of the work lies in supporting your upgraded cleanroom with regular maintenance and cleaning. Follow through with regular maintenance tasks like cleaning procedures, replacing pre-filters, and servicing equipment to make sure your cleanroom stays in top condition.

Your cleanroom should be checked regularly to make sure it complies with your classification standard. If your cleanroom falls in the ISO Class 5 or lower category, it will need to be monitored with particle count tests biannually, per ISO 14644-2. Cleanrooms with less stringent standards are checked once each year.

Keep up with scheduled maintenance and monitoring tasks to make sure your cleanroom meets its new standards completely and consistently.

3 Common Types of Cleanrooms

by Evenbound - Hunter | Jul 16, 2020 | Cleanrooms

If you know you need a controlled space to operate your business, a cleanroom is designed to help you achieve a completely clean environment to work, while managing environmental factors like temperature, humidity, static, and pressure. Whether you’re manufacturing, developing, inventing, testing, or packaging, various cleanroom types will offer you different features. Some might be better suited for certain cleanroom classifications or offer special features or more compatibility with your unique application. Let’s take a look at three common types of cleanrooms: HardWall, SoftWall, RigidWall cleanrooms.

HardWall Cleanrooms

For cleanrooms with rigorous classification standards, HardWall cleanrooms are designed to comply with any cleanroom classifications, even the most stringent (ISO Class 1).

HardWall cleanrooms can be freestanding or incorporated into an existing building. Made using a coated aluminum frame with a prefabricated panel, HardWall modular cleanroom panels are designed to achieve a high level of control over static, pressure, humidity, and contamination.

A great advantage of HardWall cleanrooms is that they can be installed in an existing structure around mounted equipment, using light from the building’s windows and connecting to the existing HVAC system. This cleanroom type also offers extreme environmental control beyond particle count and air changes. In addition to management of temperature, static, and humidity, HardWall cleanrooms can be pressurized if your classification requires extra contaminant protection.

HardWall cleanrooms can comply with any industry specific requirements and are well suited for all cleanroom applications such as medical cleanrooms — including research and pharmaceuticals — aerospace cleanrooms, and even sensitive electronics manufacturing or semiconductor cleanrooms. HardWall cleanrooms can be easily modified or reconfigured by adding or removing modular panels, and are durable enough to be reused, relocated, and repurposed while maintaining their quality.

SoftWall Cleanrooms

SoftWall cleanrooms are a minimalist, lightweight cleanroom type that can accommodate most cleanroom classification standards. SoftWall cleanrooms can fit in almost any space and are fully customizable with a wide variety of filtration options, door types, and other modifications.

Featuring an aluminum alloy frame and clear or opaque vinyl curtains around the perimeter, SoftWall cleanrooms are designed to be more compact, so they can work almost anywhere in your facility — even within another cleanroom. Of course, if you’re looking to expand, custom sizes are available. Curtains are made from anti-static or conductive PVC or polyethylene. 40 mil clear is the standard option, but frosted or clear anti-static vinyl are also available as well, in a range of colors for UV absorption. During installation, wiring is installed on-site, with optional pre-assembled wiring harnesses. You can also choose to install standard fan filter units and a control panel for FFUs, lighting, and other wiring.

SoftWall Cleanrooms are able to reach most cleanroom classifications, and are ideally suited for ISO Classes 4-8.

If you’re looking for an affordable cleanroom option that’s easy to assemble and maintain, a SoftWall cleanroom would be perfectly suited for your application. SoftWall cleanrooms have the advantage of being an affordable modular option that don’t sacrifice their high performance capacity. Their extremely flexible design makes them a great choice for applications that need room to grow, including plastics manufacturing, automotive cleanrooms, growrooms, and some medical cleanroom applications.

RigidWall Cleanrooms

RigidWall cleanrooms can also provide a suitable environment for applications with less stringent classification requirements, with some flexibility that allows you to make changes as necessary to the layout and design of your cleanroom. RigidWall panels have a durability comparable to HardWalls, with full visibility floor to ceiling. They are best used for cleanrooms with classifications ISO Class 5-8.

With a choice of acrylic, static dissipative PVC, or polycarbonate wall panels, a RigidWall cleanroom will house your operations in a transparent, attractive style. Unlike the SoftWall curtain or the utilitarian HardWall panels, RigidWall panels are sleek and minimalist. Flat, clear panels allow easier monitoring of the cleanrooms while also creating an attractive feature for the space, making them a perfect frame to show off your work to investors.

An advantage of RigidWall cleanrooms is that they are easy to maintain. Although they aren’t as flexible as SoftWall panels, RigidWalls can be modified with some effort, or even stored if you need to free space for something else. RigidWall panels can be customized in size with heights up to 7-14 feet, and come pre-wired with outlets and switches to control lighting, fans, and equipment. Panels are suspended from a strong ceiling grid which, fully-secured, means the panels will maintain their shape and integrity over time.

RigidWall cleanrooms make a high-performance choice for a number of applications such as automotive cleanrooms, aerospace cleanrooms, and some medical device packaging and plastics cleanrooms.

All cleanroom types can be fully customized or modified to your unique application. Whether you need a highly controlled environment to meet stringent cleanroom classification requirements or an affordable option to allow your operations to grow, a HardWall, SoftWall, or RigidWall cleanroom would be a great choice for your facility.

5 Benefits of Hardwall Cleanrooms for the Aerospace Industry

by Evenbound - Hunter | Jun 4, 2020 | Aerospace Cleanrooms, Cleanrooms, Hardwall Cleanrooms

Aerospace cleanrooms often require high levels of control, regulated by high cleanroom classifications. To achieve stringent standards, while allowing flexibility for project changes and environmental adjustments, some of the best cleanrooms for the aerospace industry are HardWall cleanrooms. Let’s look at five benefits HardWall cleanrooms can offer your aerospace projects.

HardWall Cleanrooms Are Stable

When working within a cleanroom environment, having control over environmental variables can make or break a project. That’s why a stable cleanroom is so important for all cleanroom applications, but especially for those with higher cleanroom classifications. At best, instability can make your work unpredictable and unproductive; at worst, someone could get hurt. To avoid these scenarios, you need a cleanroom you can trust to keep your products and people safe; one that will allow you to control your environment and limit contamination by unwanted forces or particles as much as possible.

HardWall cleanrooms offer the most stability of any modular cleanroom. Particularly for higher classification and specialized aerospace cleanrooms, this cleanroom type offers more control across a wide range of requirements. The sturdy floor-to-ceiling panels create a fully sealed space for total power over environmental factors like temperature, humidity, and pressure. If your cleanroom needs the ability to control minute differences effectively and conveniently, a HardWall cleanroom is the best choice for your project.

How Often Should I Maintenance My Cleanroom?

by Kolby Kloosterman | May 26, 2020 | Cleanrooms, Filtration, Helpful Tips

Proper cleanroom maintenance is not only important to keep a cleanroom running efficiently and limit dangerous contamination of processes, but it can also save your company money. Improper cleaning or maintenance of your cleanroom could be costly, even dangerous, and could lead to liability issues — especially in sensitive industries like pharmaceutical cleanrooms, manufacturing of fine electronics, or the development of medical devices. Regular and thorough maintenance keeps a cleanroom in good operational shape and establishes a safe space for employees to work.

The ideal maintenance schedule for your cleanroom will depend on its classification and cleanliness standards. A general recommendation for cleanrooms with an ISO Classification from 1-5 is to schedule semi-annual inspections of their equipment and systems, while cleanrooms with ISO Classification from 6-9 can manage with annual checks. Keep in mind, some components of the cleanroom require more consistent maintenance, such as its filters.

Cleanroom Maintenance Areas

Whether your cleanroom follows a strict maintenance schedule on its own or works with an outside contractor, the most important cleanroom maintenance areas include filtration, the HVAC system, and your industry-specific equipment.

Air Filtration System

Most cleanrooms use three sets of filters to collect particles from the air. The outermost filters, or pre-filters, require the most maintenance as they are the first line of defense, protecting the innermost — and most expensive — HEPA filters.

Pre-filters can be assessed by checking differential pressure or air outflow velocity. On average, they will need to be replaced 6 times per year. Bag/box filters function as intermediary filters and are generally replaced annually. HEPA filters should be replaced about every three years, but must be checked periodically to ensure that they are functioning properly. All filters should be assessed regularly to determine their effectiveness.

Be aware that your cleanroom’s location can affect the schedule of filter replacement. For example, if your building is located in an area that experiences more air pollution or possible contaminants, such as next to a freeway, railroad track, or factory, it might require more frequent filter checks. You can use air samplers or settle plates to test the air quality within your cleanroom, and make changes to your cleanroom’s filter replacement schedule as necessary.

Cleanroom Equipment

Your industry-specific cleanroom equipment will likely require regular maintenance to make sure it serves your needs effectively. This may include equipment like fume hoods and boilers, as well as important cleanroom areas like the gowning room and waste-disposal areas.

Cleanroom equipment maintenance will require the cleanroom to be shut down, so it is important to plan ahead to minimize disruption. It’s best to bundle cleanroom maintenance tasks together, such as replacing pre-filters while upgrading or repairing the equipment that your cleanroom contains, as well as the furniture that supports it.

Cleanroom HVAC System

Your cleanroom’s HVAC system should receive regular maintenance to make sure it’s running efficiently. Inefficient HVAC systems use more energy and run a higher risk of failure. When assessing your HVAC system, you should test that it meets all necessary temperature, pressure, and humidity requirements.

It’s recommended that you perform cleanroom maintenance on your HVAC system at least twice per year, in the spring and fall. When the climate changes seasonally, different factors of your system will be prioritized, so biannual checks will ensure a smooth and consistent transition throughout the year. HVAC maintenance could include tasks like: cleaning coils and drain lines, checking for gas or fluid leaks, checking that all electrical connections are sound, making sure the fan motor is in peak condition, lubricating any moving parts, checking heating elements, and making sure the thermostat and controls are reading accurately and functioning well.

Preventative Cleanroom Maintenance

To facilitate or reduce maintenance tasks, you should employ an efficient cleanroom design and follow regular cleaning procedures.

Cleanroom Design

Your cleanroom layout should be simple and intuitive, with clear paths for employees to follow to limit particle-shedding. Your cleanroom should have limited access points, ideally just one. Control the selection and placement of furniture within your cleanroom to allow air to move freely and not cause a buildup of contaminants within the space. Having an intentional design minimizes cleanroom maintenance needs and reduces the risk of contamination.

Cleaning Your Cleanroom

Regular cleaning is a crucial part of cleanroom maintenance. All cleanrooms should have a regular cleaning schedule to meet class standards and follow proper strategies for sanitization including using the correct cleaning materials for your classification and educating staff about proper cleaning procedure.

Your space should have adequate storage for all cleaning and cleanroom maintenance materials, such as cleaning solutions and supplies, ladders, and appropriate tools. All storage should be cleaned and maintained regularly and be in an accessible place where the possibility of contamination is minimized.

Benefits of Third-Party Cleanroom Maintenance

Using an outside contractor for maintenance, equipment service, and cleaning can help establish consistent cleaning and maintenance procedures as well as help to avoid potential problems from doing the work yourself. An outside contractor is:

Dedicated to delivering high standards of cleanliness and proper equipment maintenance. Let your employees focus on their work within your cleanroom. Having workers also be responsible for cleaning and maintenance could lead to complacency and a gradual decline in standards.
Trained for proper cleanroom maintenance with your industry-specific equipment. Third-party contractors understand the importance of proper cleanroom maintenance and, unlike general janitorial staff, can complete the work with a high degree of efficiency and detail to your class standards.
Quality-assured and accountable. An outside contractor is committed to reaching your cleanroom standards and facilitating a safe work environment for your employees. There is clear documentation that demonstrates completed cleanroom maintenance tasks, which limits your personal liability.

An outside contractor will make sure your cleanroom is always meeting its rigorous class standards while being operational and safe for staff. They understand the functions of your unique cleanroom and can help establish a regular cleaning and maintenance schedule to keep things running smoothly.

Anti-Static Cleanrooms: What’s the Deal?

by Kolby Kloosterman | Apr 2, 2020 | Cleanrooms

There’s a cleanroom type for every application. Many industries have specific requirements in order to perform their work successfully and without any contaminating — or dangerous — interruptions. Anti-static cleanrooms are an important type of cleanroom for industries where a stray spark or electric current could prove disastrous to projects. Let’s take a closer look at what an anti-static cleanroom is and how it serves special applications.

What is an anti-static cleanroom?

An anti-static cleanroom is a type of cleanroom in which every part is designed to minimize or eradicate static electricity — from flooring panels and anti-static wall material to gowning garments and procedures. Anti-static cleanrooms are especially useful in applications that involve electronics or electrically-sensitive substances. Errant electricity can interfere with experiment results or alter the readouts of important machinery, compromising the scientific process. By controlling the effects of static, you can avoid being electrically charged, and stick to just being in charge.

What makes a cleanroom anti-static?

It takes careful planning to make a cleanroom anti-static. Anti-static cleanrooms use electro-static dissipative finishes and equipment whenever possible. Their components include anti-static flooring, wall panels, and furniture as well as specific garments that dispel or minimize the buildup of electricity.

Anti-Static Flooring

Static electricity builds naturally in most environments, but it is especially dangerous in certain cleanroom applications. Anti-static flooring minimizes electricity by grounding or dissipating any buildup of charges. Anti-static cleanrooms use either static-dissipative flooring or conductive flooring.

Static-Dissipative Flooring

Static-dissipative flooring uses rubber or vinyl sheets that disperse electricity. This type of flooring is common in cleanrooms for electronics and manufacturing. Since it can allow more charge to build up before releasing, static-dissipative flooring is not recommended for extremely sensitive cleanroom applications, particularly those that involve flammable liquids or sensitive electrical parts.

Conductive Flooring

Conductive flooring uses a copper strip which is connected to a grounded outlet. It allows less charge to build up before grounding, which is more effective in applications where even minimal charges could be hazardous.

Anti-Static Wall Panels

A variety of wall panels are compliant with anti-static requirements. Aluminum rigid wall panels make a great anti-static option that is lightweight, noncombustible and non-particle-shedding. They are made with a “honeycomb” core which helps control static buildup. Modular stainless steel panels can also be anti-static and have conductive properties which are useful for cleanrooms with sensitive materials.

For a softwall option, flexible vinyl sheeting can be treated to be anti-static. It is an excellent choice for compact or temporary cleanrooms that require efficient static-dissipative applications.

Anti-Static Furniture

Even the furniture in an anti-static cleanroom must be static-dissipative. Special non-conductive mats can be used on top of anti-static flooring for problem areas, adding an extra layer of protection for employees. Chairs, tables, and other surfaces must also be made with materials that are non-conductive or static-dissipative.

Depending on the specific equipment your cleanroom holds, your tools should also be chosen with the intention of minimizing static. Some machines may need modifications that allow grounding of static electricity or be reconfigured within your cleanroom to promote dissipation.

Anti-Static Clothing

Garments worn within an anti-static cleanroom are selected specifically for this use. Static-dissipative clothing is made from electro-static discharge (ESD) fabric. Depending on your cleanroom’s use, you may need to outfit your employees completely to protect them from electric shock. ESD fabric and materials can be used to make many types of clothing, including gowns, coveralls, shoes, hoods, sleeves and gloves.

Air Ionization

Anti-static cleanrooms also make use of air ionization to remove particles that might attach and contaminate cleanrooms. Ionization neutralizes static electricity in the air, which is useful for removing particles and contaminants that could attach during gowning, for example. Ionization systems are more effective than air showers because they counteract static, making particles easier to remove, unlike air showers which are unable to remove particles that are too strongly attracted.

Ionization systems are also very effective at reducing particle counts when installed in gowning areas. They are only effective on non-conductive materials, so it’s recommended to combine them with additional static control methods.

Why do I need an anti-static cleanroom?

In cleanrooms where static poses a high risk, static-dissipative finishes, equipment, and procedures are essential to protect products and employees. In some settings, sparks from static electricity buildup could cause significant damage, from small fires to explosions of flammable chemicals. It’s better to prepare a safe environment with an anti-static cleanroom and minimize the dangerous accumulation of electricity than wait until an accident happens.

Cleanroom Design Tips: Choosing Cleanroom Flooring

by Evenbound - Hunter | Mar 23, 2020 | Cleanroom Design, Cleanrooms

When designing the perfect cleanroom, every element has to fit together. Working from head to toe, each component has a part to play in keeping your cleanroom running efficiently. When it comes to flooring, you’ll need to pick the type that best fits the work you’re doing, the materials you’re using, and adds to the cleanliness of your space.

Before choosing your cleanroom flooring material, consider what requirements your cleanroom has to meet and the type of traffic and wear it receives. Maybe you need a material that can handle harsh chemicals for cleaning or manufacturing processes. Or perhaps your industry deals with electronics whose main enemy is static electricity, and you need flooring that will dissipate static and protect your work.

There are several common flooring materials for cleanroom design, each with advantages and qualities that make them more qualified for certain applications over others. Here are some of the most common flooring types for cleanrooms:

Cleanroom Flooring Types:

Rubber Flooring

Rubber flooring is installed in sheets and then cold welded into place. It can stand up to heavy wear, making it one of the most durable choices of cleanroom flooring. Rubber sheet flooring is also anti-static and easy to maintain. It’s a low-cost option that is available in many colors that can match any cleanroom design. Rubber flooring is the favorite of many cleanroom designers because it is easy to install and can meet a large variety of operational requirements.

Vinyl Seamless Flooring

Vinyl flooring is one of the easiest to clean because of its seamless construction. It can also be used to cover walls in a smooth transition, meaning fewer crevices for contaminants to build up. Vinyl flooring is a very economical option for low-traffic cleanrooms that don’t have to meet high weight requirements. Consistent traffic will wear out vinyl flooring quickly.

Epoxy Coating

Epoxy is a coating that is installed over a solid concrete substrate, preferably one that has no cracks and is structurally solid. Epoxy will fill in small imperfections on the floor’s surface, so some leveling is required. Epoxy’s advantage is its dense coating which has a low porosity, making it strong and durable under heavy traffic as well as easy to clean and maintain. It can be applied in a variety of color and performance options that can stand up to corrosive chemicals and dissipate static.

Urethane System

Polyurethane flooring exhibits a glossy or satin finish that is maintained even under heavy traffic and use. It is highly resistant to harsh chemicals and substances like gasoline, fuels, hydrocarbons, acids, and alcohols, making it an excellent cleanroom design choice for manufacturing cleanrooms. It also has light-reflecting properties that aid in illumination and can have applications that prevent skids.

Others:

Another cleanroom flooring type is Vinyl Composition Tile (VCT). VCT has many seams that require consistent maintenance but is a cost-effective option that complements applications in electronics because of the electrostatic dissipative feature.

Raised flooring panels can be used to improve airflow within a cleanroom. They also increase conductivity and may be static dissipative. Raised panels can be solid panels, grated or perforated.

Depending on the unique specifications of your facility, some flooring types will be better able to accommodate your needs than others. If you’re planning the design for your new cleanroom and are still unsure which flooring type to go with, let the experts at Angstrom Technology help. Our design experts can help you make the tough choices, and ensure you get the cleanroom that’s perfect for your application.
