What is a Cleanroom? An Overview

A cleanroom is a controlled environment that is designed to remove pollutants like dust, airborne microbes, and aerosol particles. Pollutants are filtered out to provide the cleanest environment possible for a variety of applications, from manufacturing and pharmaceutical to scientific research. 

How Clean is Clean?

Every cleanroom has a specific cleanliness level, which is quantified by how many particles exist in the room per cubic meter. We’ll talk more specifically about different cleanroom classifications later on, but it is good to know that every industry, and even every application, might require a different level of cleanliness. 

How Long Have Cleanrooms Been Around?

Cleanrooms, as we know them today, didn’t really get their start until the early 1960s, when physicist Willis Whitfield invented a cleanroom with constant airflow that flushes out any harmful particles.

How Do Cleanrooms Work?

Cleanrooms make use of airflow and high-tech filters to rid the controlled environment of any particles that could contaminate the research, development, or manufacturing field. Cleanrooms make use of either negative or positive air pressure to control how clean the environment is. 

A cleanroom with positive air pressure has clean, filtered air pumped into the environment, giving it more pressure than the rooms around it. If the door was opened to the cleanroom accidentally, clean air would be forced out of the cleanroom, blocking any unfiltered air from coming in. 

A cleanroom with negative air pressure has a lower pressure than the rooms around it. This is achieved by filtering air out of the cleanroom, rather than pumping air in. Negative air pressure cleanrooms are used in cases where the goal is to keep contamination from escaping the environment. 

For more information on negative and positive air pressure cleanrooms, check out this blog: What’s the Difference Between Positive and Negative Air Pressure Cleanrooms.

What is a Modular Cleanroom?

A modular cleanroom is a cleanroom made from pre-fabricated components. While modular cleanrooms can be as permanent as a cleanroom that’s built with stud and drywall, they’re easier and faster to build and are easily modified in the long-run. 

The main difference between a modular cleanroom and a traditionally constructed cleanroom are the materials used, and the speed of the build. For these reasons among others, many companies in a variety of applications choose modular cleanrooms. Here are a few of the additional benefits of a modular cleanroom:

Benefits of a Modular Cleanroom

Modular cleanrooms are a popular build option for most industries. With all of the same features of a traditional cleanroom, modular cleanrooms are easily constructed in half the time, with greater flexibility and at considerably less cost. Here’s a breakdown of a few key benefits of a modular cleanroom:

Simple, Efficient Build

When you commission a modular cleanroom, the entire room is manufactured to your direct specifications, off-site. It’s then sent to you, where the entire kit is easily assembled with minimal tools and minimal time. 

There’s no need to find a site, do any excavating, or construct walls. Every component of your cleanroom is sent to you, pre-fabricated. All that has to be done is put it together, or have an installation pro put it together for you in just a few days.

Build Anywhere, in Any Facility

One benefit that many modular cleanroom owners love, is that a modular cleanroom can be built anywhere — even in an existing facility. There’s no need to rent new space or break new ground. You can have a cleanroom designed in the middle of a large open production floor, or tucked back in your warehouse’s office space. Put your new modular cleanroom wherever you need it most.

Modify or Expand at Your Convenience

Since modular cleanrooms are made from pre-fabricated panels, they’re easy to modify. Make your cleanroom bigger, smaller, or take it down when your project is over and put it in storage until you need it again. Modular cleanroom components are lightweight and easy to move around, allowing you to reconfigure your cleanroom space for any new application or change in production.

Three Main Types of Modular Cleanrooms

Believe it or not, modular cleanrooms aren’t all the same. Depending on your application, you have a few choices for the material your cleanroom is made out of. There are three main types of modular cleanrooms: Hardwall, Softwall, and Rigidwall. The difference in each is the type of material the walls are made out of. Let’s take a look at each:

Hardwall Cleanrooms

Hardwall cleanrooms are made out of solid material, like stainless steel, vinyl, plastic laminate, aluminum, or fiberglass reinforced plastic. Cleanrooms like these are best for applications that must comply with a high standard of cleanroom classification because they are the most secure, and the easiest to clean. A Hardwall cleanroom can be engineered to comply with any standard, which makes it a versatile option. 

Hardwall cleanrooms are also preferred for their durability, simple installation, and easy modification. Since Hardwall cleanrooms can be made to fit any standard, they’re great for companies who may be advancing their capabilities down the road. They’re easy to modify and upgrade, and they’re also very simple to maintain. If you have an expanding facility or need a cleanroom that can comply with very high standards, a Hardwall cleanroom is likely the best choice for you. 

Softwall Cleanroom

Softwall cleanrooms are, as the name suggests, much lighter than Hardwall cleanrooms. Softwall panels are constructed of a clear vinyl sheet and the framework comes in a standard white powder-baked enamel finish that makes them very easy to maintain. Capable of meeting Class 10 to Class 100,000 standards, Softwall cleanrooms are often chosen for their extreme affordability, and for the fact that they can be installed just about anywhere. Choose to suspend a Softwall cleanroom from an existing building or make it freestanding. Since Softwall cleanrooms are so compact and customizable, they can be made to fit nearly any space. 

Many companies choose a Softwall cleanroom when they need a cleanroom that meets certain specifications, but doesn’t require the highest standards such as temperature or humidity control. Since they are so affordable and flexible, Softwall cleanrooms are great for larger applications, and for custom cleanrooms that require unique features like an airlock or ULPA filters. 

Not sure if a Softwall or Hardwall cleanroom is best for your application? Check out this article about Hardwall Vs. Softwall Cleanrooms, or keep reading to learn about the third type of cleanroom.

Rigidwall Cleanrooms

One of the most versatile cleanroom options on the market, Rigidwall cleanrooms offer you the structure of a Hardwall cleanroom with the visibility of a Softwall cleanroom. Most sizes easily installed in 2-3 days, Rigidwall cleanroom components are made from crystal-clear, accrylic, modular panels that look great and perform even better. 

Rigidwall cleanrooms can offer contamination security from Class 100 standards to Class 100,000 standards, which means they’re perfect for a variety of applications. Like other modular cleanroom material options, Rigidwall cleanrooms are flexible, and can easily be modified or expanded to fit new processes and changing.

Starting a Modular Cleanroom Project

Now that you know what a modular cleanroom is, why companies use it, and some of the various modular cleanroom materials available, you’re probably ready to figure out how you can get a new modular cleanroom project started. 

Whether you’re just considering installing a cleanroom, or you’ve already gotten approval, this next section will cover some of the key steps to getting started with a modular cleanroom project. First up: determining your cleanroom’s classification. 

Step 1: Cleanroom Classification: What You Need to Know

Every cleanroom design starts with a specific standard or classification. While there are a few different classification scales (which we’ll get to next) the general purpose of determining your cleanroom’s classification is to see just how clean your cleanroom has to be. A cleanroom’s classification refers to the maximum acceptable number of particles (by size) in the air per cubic meter. 

Here in the US, most industries rely on two classification scales, International Standards Organization (ISO) and the U.S. General Service Administration Standards (FS209E), to determine the cleanliness of any given cleanroom. You can take a look at the specific breakdowns of both of those classification scales on our Cleanroom Classifications & Standards page. 

How Do I Know What Classification My Cleanroom Must Meet?

Typically, your industry will have specific guidelines for which classifications your cleanroom should meet, depending on your specific application. But, if you’re not sure what those requirements are, or where to look, here are a few questions that can get you started down the right path:

What Size Particles Do You Need to Filter Out?

The biggest question your classification standard can answer is what size particles you need filtered out. For example, if you’re working in nanotechnology or microelectronics, even the smallest particles can be detrimental to the performance of your products. You’ll need a higher cleanroom classification with the technology to keep tiny particles from interfering with your employees’ work. 

If you’re working in a more traditional automotive manufacturing setting, you might just be worried about larger particles disrupting sensors and other key components. While you still need a cleanroom, you probably won’t need the same level of technology and filtration as someone in the nanotechnology field. Your cleanroom will likely fit a lower classification standard. 

Where Are Contaminating Particles Coming From?

As you already know, cleanrooms work to keep contaminants out. They provide a safe, controlled environment for your products and processes, so you can manufacture and assemble without defects. Think about the contaminants your cleanroom will have to keep out. Where are they coming from? 

The amount of contaminants in your environment, and where they’re getting into your cleanroom, can also affect the classification standard your cleanroom must meet. 

How Much Air Do You Need to Keep Those Particles Out?

The final component of determining your cleanroom classification standard is how much air you’ll need to keep those particles out. ISO standards, which we mentioned above, actually come with a recommended number of air changes per hour. 

This refers to how many times per hour the air in your cleanroom is exchanged for new, filtered, and clean outside air. A cleanroom can change air anywhere from 10 to over 600 times an hour, depending on the classification standard your cleanroom has to meet. The stricter your cleanroom’s standards, the more air changes your cleanroom will need per hour. 

For more help determining what classification standards your cleanroom should meet, check out our Cleanroom Project Design Guide or this article What You Need to Know About Cleanroom Classifications. In most cases, your industry likely specifies the standards your cleanroom must meet for your application, but you might also consider taking a look at this bulleted list below for a general reference:

• Biotechnology — ISO Class 5 to ISO Class 8
• Pharmaceutical — ISO Class 5 to ISO Class 8
• Semiconductor — ISO Class 1 to ISO Class 6
• Optics — ISO Class 1 to ISO Class 6
• Defense — ISO Class 1 to ISO Class 6
• Medical Device — ISO Class 7 to ISO Class 8
• E-liquid and vaporizer — ISO Class 7 to ISO Class 8
• Nanotechnology and Microelectronic — ISO Class 1 to ISO Class 6
• Automotive — ISO Class 7 to ISO Class 8
• Manufacturing —  ISO Class 7 to ISO Class 8
• Hospital — ISO Class 5
• Food — ISO Class 6
• Aerospace — ISO Class 5 to ISO Class 8

Step 2: Cleanroom Design

Once you know what classification standards your cleanroom needs to meet, you can get to the actual work of designing your cleanroom. For the most part, all cleanrooms function in much the same way. They either push clean, filtered air in, or pull filtered air out. Either way, there are three major factors that will affect how you design the perfect cleanroom for your application. Let’s take a look at each of those, to help you get a better feel for what your new cleanroom will look like. 

Budget

Your budget is a key factor in your cleanroom design. We always recommend clients start with a budget upfront, so we know what we’re working with, and so we can design a cleanroom that meets your specifications, without going over your budget. 

Looking to save a few pennies on that new cleanroom? Here are a couple of ways you can reduce the overall cost of your cleanroom:

• Opt for Shorter Ceilings — The bigger your space, the more air you’ll have to pump in to make sure you’re meeting the required air exchange rate for your cleanroom’s standards. And the more air you have to pump in, the higher your operating costs. A room with 10 foot ceilings, rather than 8 foot ceilings, is 25% larger, and almost none of that additional space is functional for your application. If you’re hoping to save a bit on the overall cost of your cleanroom, consider using only as much space as you need, as well as consulting with a cleanroom design and installation expert who has the experience to offer tips like this.
• Consider Starting Small and Growing with your Level of Business — Because modular cleanrooms are so easily expandable, you can grow the size of your room to match the size of your business.  When initially installing a cleanroom, focus on your current needs, and rest assured that your modular cleanroom can be adjusted if a new customer or contract were to come in.

Size

The size of your cleanroom is also something to know before you start designing. Think about how many employees you’ll need in the space, what equipment you’ll have to have, and any other considerations, like room for storage. Determining the size of your cleanroom will give your cleanroom design and installation professional an idea of:

• How many filters you’ll need
• What size HVAC system might be required
• How many wall panels your cleanroom will need
• How much lighting you’ll need
• What temperature and humidity concerns to keep in mind

It’s good to remember that when you’re designing a modular cleanroom, you should always design for your current needs. Modular cleanrooms are easily adapted to any changes that could happen in the future, so work to design your cleanroom to fit your current application. If you need to add on or take some space away in the future, that’s easily done thanks to modular cleanroom construction.

Location

Deciding on the size and budget for your cleanroom will also make it easier for you to narrow down the perfect location. 

If you have a smaller budget, and are looking at a smaller cleanroom, you might have the space for it in your existing building. Modular cleanrooms are easily constructed within buildings, and can be suspended from your building’s ceiling, and even potentially connected to your existing HVAC system. 

If you’re working with a bit more money, you can also find an offsite location, or build your cleanroom as an expansion of your existing building. 

Because modular cleanrooms are so flexible, the location of your new cleanroom project will depend primarily on what’s most convenient and affordable for you.

Key Components of Cleanroom Design

When you know the budget, size, and location for your new cleanroom, the real design work can begin. If you’re working with a cleanroom design and installation expert, this is the point where they’ll come out and perform an on-site inspection. This helps them get a better idea for your space, and better customize your cleanroom design to your unique application. 

If you’re new to cleanroom design, here are a few of the key components you’ll want to make sure you consider in your cleanroom design:

Flooring Material

Cleanroom flooring is an essential component working to keep your cleanroom particle-free. In general, most applications use either perforated raised flooring, seamless vinyl, or epoxy paint on concrete. Each of these three flooring material options ensure that no particles are trapped in cracks in the floor, and work to make cleaning as easy as possible. 

Filter Types

Filters are likely to be one of the biggest investments you make in your cleanroom design project. There are also three types of filters used most often in cleanrooms:

• Prefilters — Used with both HEPA and ULPA filters, prefilters work to filter out the largest particles in the air. Essentially, they save the bigger, more expensive filters a little work, and ensure you get a bit more bang for your buck.

• HEPA Filters — The most commonly used cleanroom filter, HEPA filters (High-Efficiency Particulate Air filters) work to remove particles 0.3µm or larger. HEPA filters work to filter out 99.99 percent of those particles. 
• ULPA Filters — ULPA (Ultra Low Particulate Air filters) are used in applications that require the removal of the smallest particles possible. They remove 99.999 percent of particles larger than 0.12µm.

Lighting Options

If you’re new to cleanrooms, you may be surprised to learn how important lighting can be to the overall design of your cleanroom. It’s essential to efficient operations within your cleanroom, and it can also have an impact on the overall operating cost of your cleanroom. When designing your cleanroom, a cleanroom design and installation professional will determine how many fixtures you’ll need, where those fixtures should go, and how bright your lights will need to be for the best results. Then, you’ll be able to choose the type of lighting that works best for you, from fluorescent to incandescent to LED.

Specialty Components

And once you have the basics, like filters, flooring, and lighting, figured out, you’ll also want to think about any specialty components of your cleanroom’s design. It’s good to remember that any cleanroom’s greatest enemy is anyone entering or leaving. A well-designed cleanroom will function at its classification standard in perpetuity if no one ever opens the doors. These specialty components help your cleanroom protect against invading particles as your employees enter and exit the controlled environment:

Airlocks

Airlocks help prevent particles from entering your cleanroom when personnel enter or exit the controlled environment. If your cleanroom requires a high classification standard, or if you’re just looking for ways to boost the efficiency and cleanliness of a lower classification cleanroom, an airlock is a great tool. Learn everything you need to know about airlocks here. 

Gowning Rooms

While every cleanroom has a slightly different gowning process, if your employees need to wear special equipment while in the cleanroom, it’s a good idea to install a gowning room alongside your cleanroom. This provides a clean space for your employees to don their required personal protection equipment, and can help reduce the number of particles they track into your cleanroom. Here’s what you need to know to get started with gowning rooms, and teach your personnel proper gowning procedure. 

Air Showers

Like an airlock, an air shower is an added barrier between your cleanroom and the outside world. Unlike an airlock, an air shower packs an extra punch. Air showers blow filtered air at your employees to “scrub” them of any particulates before they enter the cleanroom. While air showers are often required for higher classifications like ISO Classes 1 and 2, they’re a good idea for nearly any cleanroom, as they require your cleanroom system to do less work to keep the environment particulate-free. Here’s a bit more information about cleanroom air showers and their cost. 

Pass-Through Chambers

Pass-through chambers are an excellent addition to any cleanroom application that requires you pass materials in and out of the cleanroom on a frequent basis. Easily installed in existing cleanrooms as well as new designs, pass-through chambers make it much easier for your employees to do their work efficiently, without having to de-gown, exit the cleanroom, and then re-gown, just to pass material outside of the controlled environment. 

How A Cleanroom Firm Can Help You Design The Right Cleanroom

After reading about all of the components that go into cleanroom design, you might be feeling a little overwhelmed. That’s where a cleanroom firm comes in. If you’re planning a cleanroom design and installation project, it’s helpful to have someone at your side who understands all of the many components of a cleanroom, and who can help you design a cleanroom that fits your classification standard, your space, and your budget.  

That’s where Angstrom Technology comes in. As one of the most innovative cleanroom firms in the industry, we not only design and install cleanrooms, but we also supply cleanroom components and products, ensuring we can help you through every step of your project, from start to finish.

Step 3: Cleanroom Installation

The cleanroom design stage is a rigorous process. It is certainly the longest step to developing a new cleanroom, and for good reason — once your modular cleanroom is completely designed, it can be shipped right to your door, where you can easily install it in days, and even just hours, depending on the materials you choose and the size of your cleanroom.

Installing A Modular Cleanroom

One of the key benefits of investing in a modular cleanroom is that it’s so easy to install and assemble. All of the components of a modular cleanroom are built to fit your unique site, perfectly, before they are shipped to you. Here are just a few of the benefits that come with installing a modular cleanroom:

• Prefabrication — The most obvious benefit of a modular cleanroom is that all of the components are prefabricated. That means they’re built to a standard size so that every component fits perfectly together. You don’t have to worry about how your equipment will fit in the cleanroom or if a pass-through chamber is the right size for your space. It is already designed and manufactured for your unique specifications.
• Easy Electrical — When you work with a reputable cleanroom firm, like Angstrom, your cleanroom’s wall panels will arrive pre-wired for quick connection when it’s time to install your cleanroom. That means you don’t need an electrician or specialty installation help, which speeds up your installation time.

• Structure to Fit Your Facility — Modular cleanrooms are designed and manufactured to fit your unique facility. Whether your cleanroom will be freestanding or built upon your facility’s existing walls, modular cleanrooms are designed with longevity and structure in mind. They won’t sag or shift over time, and they’re built to fit your space perfectly.
• Install in Hours or Days — Since every component of your cleanroom is prefabricated, then deconstructed and shipped to your facility in order, your team can easily install Softwall cleanrooms in just a few hours, and Hardwall or Rigidwall Cleanrooms in as little as two to three days. This ensures your project is up and running in no time at all. 

While installing a modular cleanroom can be done quickly and efficiently, it’s not the right choice for every company. If you don’t have a lot of manpower on site, or if your employees are already busy with their daily operations, you can opt to have your cleanroom professionally installed. Here at Angstrom Technology, we’re here to help you. That means if you need support getting your cleanroom up and running, we’re happy to send a team out to your facility to get the work done.

Step 4: Cleanroom Maintenance & Service

Maintaining your cleanroom is just as important as choosing the perfect design. While your cleanroom will work for you to keep contaminants and particles out, your team will also have to participate in regular cleaning and maintenance to ensure your cleanroom can do its job well. That’s where a quality cleanroom maintenance and service provider comes in. 

Whether you have to comply with regular cleanroom validation, need to add on to your existing cleanroom, or are looking for some design reconfigurations to better suit your operations, it’s important to have an industry-leading cleanroom firm at your side to provide the maintenance, service, and supplies you need to keep your operations up and running. Here are just a few of the things Angstrom Technology offers our clients, to ensure their cleanrooms are always running at peak performance:
