In the aerospace industry, we’re always looking for ways to improve efficiency in your cleanroom facility. Strategies that help you achieve the same or better results at a lower cost, boost efficiency, either by reducing energy expenditures, lowering operating costs, or improving the working environment for employees to increase productivity.
Let’s explore 5 ways to accomplish efficiency in aerospace cleanroom design.
#1 Use Adaptable, Modular Cleanroom Construction
If you’re building a new aerospace cleanroom from scratch, modular construction is the most efficient way to get the new, custom cleanroom you need. Modular cleanrooms are prefabricated off-site with all of the features and systems incorporated within your cleanroom design. Each panel arrives prewired and pre-insulated so it can be easily assembled with the rest of the cleanroom, and up and running when you’re ready to use your completed facility.
The best part about modular cleanroom construction is that your space can be reconfigured or modified as your project evolves, or expanded, condensed, or disassembled and moved easily for a cleanroom redesign on a larger scale. This ability makes modular construction much more efficient than building a new cleanroom for every project.
#2 Optimize Your Efficiency: Aerospace Cleanroom Layout
If your cleanroom layout is inefficient, it can hamper productivity, and generate more particles for your cleanroom to remove. By redesigning your aerospace cleanroom and making your layout more efficient, you can improve the environment for your workers and cleanroom classification.
Try to only use as much space as strictly needed so your cleanroom is as compact as possible, while still maintaining room for personnel, equipment, products, and air to move around. With a smaller volume of air to treat and filter, your cleanroom will run more efficiently.
When designing the ideal cleanroom layout, plan out traffic patterns as well as access to storage to ensure frequently used equipment and supplies are located where they can be easily accessed by personnel. This effectively limits unnecessary movement and reduces air turbulence.
#3 Streamline the Airflow Pattern in Your Cleanroom Design
The airflow pattern is one of the most crucial elements of aerospace cleanroom efficiency. It works with your cleanroom layout to ensure there are no spaces of “dead” air or turbulent air that could deposit contaminants or where particles could settle. Once airflow uniformity has been established, you can trust that your cleanroom is always working to keep the environment as clean as possible.
An expertly-designed airflow pattern will allow your cleanroom filtration system to work most efficiently. It should evenly distribute air from input to exhaust to promote even loading of filters, which not only cleans the air in your space more effectively, but also extends the life of expensive HEPA filters.
#4 Maintain Energy Efficient Cleanroom Systems
One of the best ways to improve efficiency in your aerospace cleanroom design is to choose systems that reduce energy consumption. Finding the right lighting for your facility can help you achieve this goal. Lighting in aerospace cleanrooms needs to provide plenty of illumination for detail-oriented tasks, while conserving energy where possible. LED lighting is not only more efficient than incandescent lighting, but it’s also brighter, more durable, and requires less maintenance.
Cleanroom filtration is another area where efficiency is key. HEPA and ULPA filters are designed to thoroughly clean the air, but they are made more efficient by hardworking pre filters that remove most of the larger particles before air even reaches the HEPA filter. Because of their increased use, pre filters must be inspected and replaced according to a regular schedule to ensure they are working at peak efficiency.
Another way to maintain efficient cleanroom systems is to monitor your aerospace cleanroom HVAC. Are temperature and humidity levels optimal for your cleanroom classification and comfort? Even slight changes to temperature can make a big difference for efficiency and operational costs. Turning the thermostat up or down a degree can have a significant impact over time.
#5 Schedule Environmental Controls to Conserve Energy
Running your cleanroom at its highest levels all the time may be necessary for critical applications or facilities that conduct work on a constant schedule. But, for facilities that maintain at rest periods, adjusting environmental controls to meet a lower classification level can conserve energy and reduce operational costs.
If you schedule your environmental controls to function at a lower capacity during off times, don’t make the difference between operating levels too drastic. If your cleanroom has to expend more energy to reach a high level of cleanliness again, the practice won’t prove to be more efficient. Instead, opt for an incremental change. This will ensure that your cleanroom is conserving energy, not wasting it.

Your new plastics injection cleanroom needs to be a highly efficient machine. Every component should be considered in the design to work together to help you achieve your goals. This includes your cleanroom classification requirements and other needs and wants for your team to be successful.
Let’s explore everything you’ll need to consider when designing your plastics injection cleanroom. Then, you’ll be ready to begin cleanroom construction with the help of a qualified cleanroom engineer and supplier.
#1 Understand Your Plastics Injection Cleanroom Requirements
Before you can design the ideal plastics injection cleanroom, you need to have a thorough understanding of your classification standards and the basic requirements for your project.
Your plastics injection cleanroom classification will inform your cleanroom design in essential ways like: defining the percentage of ceiling coverage of fan filter units required to reach air particle count requirements, dictating the ideal range for temperature and humidity in your cleanroom while in operation, specifying materials that are acceptable for plastics injection cleanroom construction, and more.
Also make note of any industry-specific requirements for your cleanroom, such as the type of equipment and mounting requirements as well as the energy dependencies for the equipment you’ll be using.
#2 Compare Different Types of Cleanrooms
For plastics injection cleanrooms, modular construction can deliver the ultimate versatility for any application. There are three main types of modular cleanrooms. While all can reach the classification requirements of plastics injection cleanrooms, you may find that one type better serves your specific project needs.
Your cleanroom layout should be just large enough to accommodate equipment, personnel, air, and paths for them to move, but not too large to create extra space and air you’ll need to pay to filter, heat, and treat.
Plastics injection molding cleanrooms also typically require extra overhead space to accommodate large equipment such as overhead cranes to service molds and machinery. Extra high ceilings, nonstandard height doors and pass throughs, and a reinforced ceiling grid to support mounted equipment are all considerations for your plastics injection cleanroom design.
#4 Airflow Pattern Design Matters
Your airflow pattern design is essential to an efficient and effective cleanroom. When clean, filtered air is pumped into the controlled space, it needs a clear path to flow through the room until it is removed. Obstructions and incongruencies can impede airflow uniformity, make your cleanroom inefficient, and risk contamination.
Air balance and positive pressurization can also be considered when designing your airflow pattern, by adding more air into the room than is taken out.
#5 Work with Cleanroom Engineering Experts Can Design the Ideal Plastics Injection Facility
To design, build, and install the best plastics injection cleanroom, it’s a good idea to seek out the expertise of cleanroom engineers. Working with your cleanroom classification information and your project goals, they can help you get the highest-performing, most efficient cleanroom for your investment.

If your project needs are subject to change, how do you design a cleanroom that can meet your current and future needs? While it might seem like a good idea to build the most advanced cleanroom right away, it’s generally wiser to start small and upgrade your cleanroom over time if you need to reach a higher level of cleanliness later on. This cleanroom design approach can save energy and lower operational costs — making your work more sustainable and profitable.
Let’s discuss why starting your cleanroom design small can help you meet your current cleanroom classification, easily reach future project goals, and save your facility money in the long run.
Why Start Your Cleanroom Design Small?
If you know your cleanroom will need to meet a more stringent classification standard than required for your current project, you might be wondering, why not build a cleanroom that meets the lowest ISO level I’ll need?
The extra cushion can ensure that you’re always meeting your cleanliness requirements — but it might not be the smartest choice for your facility, or your budget. Here are three reasons to why starting your cleanroom design small, with the least stringent ISO level, is the smarter choice:
You Can Always Upgrade to a New Cleanroom Classification
By designing your cleanroom to meet the less stringent requirements, your space will be particularly suited to your initial project. When it’s time to change gears, a cleanroom redesign gives you the chance to assess each system and cleanroom component to see if it’s working for the new purpose of the room. So, while you’re adding more filtration, you can also assess if the layout, equipment, and other special features of your cleanroom are ideally suited for your new project and purpose.
Keeping your cleanroom running at the lower level of cleanliness saves energy and puts less stress on your cleanroom systems, so they can continue to work effectively — and last longer.
Modular Cleanroom Construction is Easily Adaptable
Modular cleanrooms are easy to adapt to fit new project needs. You can expand, condense, or reconfigure wall panels to meet new requirements, accommodate new equipment or a new cleanroom layout.
When it’s eventually time to upgrade, just add more wall panels, modular FFUs, and lighting, and update your airflow pattern to treat the increased volume of air. An experienced cleanroom engineer can help you do this by utilizing your existing space and systems, saving your facility money.
Energy Efficient Cleanroom Design Can Save Your Facility Money
An ISO Class 5 cleanroom requires significantly more power to maintain a controlled environment than an ISO 7 or 8 cleanroom — from the filtering power of your fan filter units to the constant treatment of air by the cleanroom HVAC system, to the flow-through lighting used to illuminate every inch of the space.
By designing your cleanroom to meet the least stringent standard (highest ISO class) you need, you can use less energy and your cleanroom systems don’t need to work as hard to meet air quality requirements, which can save your facility a significant amount of money in daily operating costs.
How to Design a Cleanroom that Grows With You
Start with the basics. Design your cleanroom to meet your needs now, and it will be easy to adapt it in the future if your needs change.
Always Start with Your Cleanroom Classification
Your first priority is always to meet your cleanroom classification requirements. Examine your cleanroom classification for the current project, paying special attention to these three areas.
Allowed particles by number and size
Air changes per hour or airflow velocity
Percentage of ceiling coverage of fan filter units
From there, you can add and adjust systems in your cleanroom that will effectively reach these levels. If you need to reach more stringent requirements down the road, you’ll want to consider how these three areas can be adjusted by adding more FFUs, upgrading your HVAC system, and so on.
Design a Cleanroom Layout That Can Be Expanded
When designing your cleanroom layout, consider starting with a smaller space to save energy in treating the air for temperature, humidity, and filtration. With less cleanroom to deal with, it will be easier to maintain your cleanroom classification. There’s also less to keep clean — which means less work and maintenance for your staff and systems.
Design your cleanroom in a way that it’s easy to expand. Note areas where you can easily add filtration support or extend walls to create space for more furniture or equipment.
Adapt Your Cleanroom Systems As Needed
Be aware that, if you upgrade your cleanroom, your cleanroom systems may need to adapt to meet a new ISO classification. This could mean a more powerful HVAC to offset the heating of the space from additional equipment, more FFUs to deliver filtered air uniformly throughout the space, or powerful but efficient lighting systems to reach expanded areas.
Every part of your current cleanroom design should be able to serve any new projects — or, be easily upgraded to meet your new requirements with optimal efficiency.

They can be fully customized to any application and built within a facility’s existing structure, making them a great cleanroom design option for virtually any ISO class or application.
5 Benefits of Seamless Cleanroom Design
Seamless cleanrooms have unique strengths and capabilities that make them the ideal choice.
#1 Modular Construction is a Turnkey Solution
Seamless cleanrooms use modular construction, where the highly customized panels are designed and fabricated offsite, so they can be put together quickly. From cleanroom design to installation, they can be up and running faster than traditional construction, making them the perfect turnkey solution for many projects.
These cleanrooms can be built in virtually any space, and their unique design means they can be easily adapted and modified, even after installation.
#2 Seamless Cleanrooms are Easy to Maintain
Seamless cleanroom design aims to minimize surfaces where particles can collect. This means your cleanroom systems don’t have to work as hard to meet cleanliness requirements, making for a more efficient operation.
Seamless cleanrooms are also easy to clean. The panels are resistant to chemicals and solvents, so they won’t shed particles or corrode, even under regular, thorough cleaning.
#3 Durable Cleanroom Design is Built to Last
Seamless panels are impact resistant, built to withstand rigorous cleaning and day-to-day wear — without shedding particles or outgassing. For a long-lasting solution, seamless cleanroom design provides the best environment for virtually any application.
#4 Full Integration With Your Cleanroom Trades and Systems
Your seamless cleanroom includes integration with your cleanroom systems and trades, such as cleanroom HVAC, filtration, lighting, and more. It can be installed in your existing structure and outfitted with all the special features you need to make your project a success.

Building a new cleanroom is a highly individual process, as it must be tailored to each facility’s needs and cleanroom classification. And this process of customization takes time. While modular construction with prefabricated panels can shorten the lead time of your project, the more “custom” your cleanroom is, generally the more time and money that must go into it.
If you need a complete and custom cleanroom that’s ready for immediate use, a turnkey cleanroom may be the ideal solution for you. Let’s explore the differences between the turnkey vs. non-turnkey cleanroom construction process to see which may serve your project needs better, be produced faster, and offer better value for your investment.
What’s the Difference Between Turnkey vs. Non-Turnkey Cleanroom Construction?
The way you move through this process of designing and installing the ideal cleanroom is significantly different if you choose a turnkey vs. non-turnkey cleanroom construction.
Non-turnkey construction refers to the practice of building a cleanroom step by step, where every component is installed separately, often by different contractors and experts, until the finished cleanroom takes shape.
Turnkey cleanroom solutions are facilitated by one party. The entire project is managed in-house, from planning and design through cleanroom construction and installation. You order the specialized cleanroom you need, and the complete solution is delivered and ready to use.
To break this down a bit further, let’s look into what you can expect with turnkey cleanroom construction vs. non-turnkey construction.
Turnkey vs. Non-Turnkey Cleanroom Construction
Turnkey solutions are a great way to get a highly specialized cleanroom — and save your company money and time. Non-turnkey cleanrooms require you to be more involved in the design and implementation, which has its own pros and cons.
Here’s what you can expect from turnkey vs. non-turnkey cleanroom construction:
Turnkey Cleanroom Solutions
You can save more than just time by finding a turnkey cleanroom solution versus going the traditional route.
Simplified Cleanroom Construction
Turnkey cleanrooms are an end-to-end solution. A thorough planning stage ensures the finished product will be perfectly suited to your project needs. One facilitator for your project, a cleanroom expert, will take time to understand your project goals, cleanroom classification standard, and any wants and needs you may have for your cleanroom.
Highly Customized Cleanroom Solution
Experts handle the entire project from start to finish. They’ll use the highest quality materials for durability and performance, using subcontractors they trust to ensure a seamless finished project that includes all the trades and features you need.
Expert Advice and Service
Even though your project is managed by someone else, it’s easy to customize your cleanroom to be exactly what you need. Cleanroom experts will take you through the process so you can be as involved with as many design decisions as you want.
Since these experts will understand your cleanroom inside and out, they’ll be the best resource if there’s ever a problem. For regular maintenance to repair, your turnkey cleanroom provider will be able to help you figure out what you need and solve any problems quickly and efficiently.
Accurate Budget and Timeline Estimate
Part of the project plan will be to estimate the budget and timeline of your project, and you can trust your cleanroom engineer to stick to it. This means a turnkey cleanroom can often be completed faster than in the non-turnkey cleanroom construction process.
When you choose a turnkey solution, you can entrust the process to experts and expect the complete cleanroom delivered exactly how and when you need it.
Non-Turnkey Cleanroom Construction
Non-turnkey cleanroom construction may take time, but if you’d prefer to handle all of the details yourself, it offers you more control over the final product.
Burden of Responsibility
With non-turnkey cleanroom construction, the party responsible for understanding the project inside and out — is you. If you know a lot about cleanroom design already, you may feel prepared to make all of the decisions for what materials to use and how to install them.
You’ll likely gather great advice from the contractors and designers you work with, but this could also lead to differing opinions and an overwhelm of information.
Complete and Manual Customization
One advantage of non-turnkey construction is that all the customizations are entirely in your hands, but you’ll be responsible for doing thorough research to find out what’s possible and cost-effective. You’ll be in charge of locating experts for each component of the cleanroom, and have to trust they can integrate each system with other parts of the project.
Complicated Maintenance and Repair
If something goes wrong with your cleanroom, you’ll have to track down the right person for the job — and if you don’t fully understand the problem, it could take more time and money to find a technician with the right experience.
Extended Timeline and Budget
Non-turnkey cleanroom construction has a tendency to extend longer than expected because it requires coordination across many schedules, waiting time for material availability, and additional time for product research.
For these reasons, non-turnkey construction is more challenging to confine to a strict budget — both monetarily and temporally — as working with different contractors, products, and vendors are variables not easily defined.
Is a Turnkey Cleanroom Solution Right for You?
Whether you’re starting from scratch with a brand new cleanroom or need to upgrade or redesign an existing one, a turnkey cleanroom could offer your facility some serious advantages. A turnkey cleanroom solution may be right for you if:
You need a ready-to-use cleanroom for your project on an accelerated timeline

Cleanroom walls, floors, doors, and other components get a lot of attention, but one of the most crucial elements of cleanroom construction is the ceiling. Cleanroom ceilings support many of the essential functions of the space, from housing fan filter units to supporting lighting and other electrical components, fire suppression systems, and more.
This is one area of medical cleanroom design that should not be overlooked. Let’s explore what your cleanroom ceiling can do — particularly when it comes to filtration and fan filter units.
Medical Cleanroom Design: Cleanroom Ceilings
Cleanroom ceilings can take many forms, depending on the requirements of each application, but the most common construction is a grid ceiling.
The grid ceiling of a medical cleanroom must support the frame and ceiling panels, lighting, and heavy fan filter units. The grid frame and all of its contents is supported by sturdy beams attached to your building structure.
With the ceiling panels installed, there should still be enough space between the ceiling and the roof for electrical and control boxes, air inlets, and fan filter unit housings. Walkable cleanroom ceilings must have enough space for a technician to maneuver above the room safely, to perform maintenance without disturbing the controlled environment inside.
Considerations for Cleanroom Ceiling Design
Cleanroom ceilings any any components, such as filters, filter housing, frames, and other penetrations for utilities, sprinklers, or lighting, must be completely sealed to prevent any contaminants from finding their way into the cleanroom. When designing the cleanroom ceiling, no wires, pipes or other obstructions should block or impair the airflow pattern from the fan filter units.
Medical Cleanroom Ceilings and Fan Filter Units
Fan filter units are the most important part of a cleanroom ceiling. They direct clean, filtered air into your cleanroom and help maintain your classification standard. They also take up the most space, so much of cleanroom design is fitting the rest of the cleanroom — lighting, electrical, and more — around these essential components.
What Are Fan Filter Units?
Fan filter units protect and facilitate the filtering power of the cleanroom. Combined with proper cleaning, and an expertly designed airflow pattern, fan filter units are responsible for achieving and maintaining your cleanroom classification requirements for allowed particles.
Fan filter units house your hardworking HEPA filters and upstream pre filters in an epoxy, acrylic or polystyrene-coated aluminum frame. They’re attached to the ceiling grid and fixed flush with ceiling panels to direct airflow into the room without creating turbulence.
Types of Fan Filter Units
There are different types of fan filter units, depending on the size, airflow rate, and filter media that works best for your application’s needs. A few of the common options for medical cleanrooms include:
Roomside Replaceable fan filter units, which feature housing that is accessible from within the cleanroom. Pharmaceutical cleanrooms require frequent testing and replacement of filters, so room-side-replacement is an advantage. These units have a gel-seal gasket that creates a seamless connection between the filter and the housing.
Non-roomside replaceable fan filter units, or NCR fan filter units, which are accessed from overhead the cleanroom. The advantage of NCR units is that they only require filter replacement every 3-5 years, except in certain cases where the cleanroom application generates excessive particulate matter.
Reverse airflow fan filter units, which are more common in medical cleanrooms working with hazardous substances, toxic fumes or contagious pathogens. A reverse airflow fan filter can be used to establish negative pressure and isolate contaminants inside the cleanroom.
All cleanrooms require air filtration using HEPA filters. Generally, the more stringent your cleanroom classification, the more fan filter units you’ll need mounted on your cleanroom ceiling.
As you install more fan filter units, you’ll need to get creative with how other systems are installed on your ceiling. Fortunately, there are creative workarounds, like grid lighting, that leave plenty of room for your cleanroom filtration system.
How Many Fan Filter Units Does My Cleanroom Need?
The number of fan filter units your cleanroom requires depends primarily on your classification, but also your cleanroom layout and the volume of your space.
Your cleanroom classification will dictate the minimum air change rate and particle count requirements for your application. Cleanrooms with less stringent requirements may only require 5-15% ceiling coverage to be dedicated to filtration, while those with fewer particles allowed may require 60-100%.
You can determine the number of fan filters required by comparing the capacity of each filter fan unit with the total volume of your space.
