Cleanrooms are special spaces designed to handle dangerous materials while keeping everything super clean. They are very important in making medicines, electronic gadgets, and biotech products. Even tiny particles or germs can cause serious problems with safety or quality. These rooms are built step by step to control contamination and protect health and products.
A cleanroom is a special place that keeps dirt, germs, and other tiny particles out. It’s built to be much cleaner and safer than regular rooms. This makes sure that the work being done inside, like making medicines or high-tech gadgets, isn’t ruined by contamination. Cleanrooms installation protect sensitive materials, keeps workers safe, and helps them do precise work without outside interference.
This article will explain the main steps of building a cleanroom, from planning how it will look to putting everything together. We’ll also talk about the important things to think about to make sure the cleanroom works well and meets all the rules.
Cleanroom Installation and Planning
When setting up a cleanroom, you need to know exactly what it needs to work well. Cleanrooms are built inside normal buildings to control things like air and temperature for sensitive work. The contractors who build them make sure everything is done right and meets all the rules so the cleanroom works as it should.
Building a cleanroom starts with planning. This means deciding how big it should be, how it will be arranged, and what the air and temperature need to be like. It’s also important to think about a few key things to make sure the cleanroom installation is done the right way:
- Identify Hazards and Vulnerabilities: It’s important to know the risks or problems that could happen with the work or products in a cleanroom. This helps decide how to design the cleanroom so it can fix or lower these risks and keep everything safe.
- Cleanliness and Airflow Requirements: Cleanrooms need to be very clean, and this is measured by a special level called an ISO rating. Another important thing is how often the air in the room is replaced, called the air change rate. Both of these help keep the room safe and working well for the job it needs to do.
- Worker Capacity: The number of workers in a cleanroom matters. More people can make the room warmer, so the air needs to be changed often, and the HVAC system must work well to keep the temperature steady. This keeps the cleanroom environment safe and controlled.
- Ceiling Height and Equipment Considerations: The height of the ceiling and the size of any big equipment in a cleanroom are important. If they aren’t planned for, they can block airflow or make the room harder to use. Designing the room with these in mind helps keep the air moving properly and the space working well.
- Environmental Data: Learning about the usual temperatures, humidity changes, and possible problems like power outages or earthquakes is important for designing a cleanroom. This information helps plan for HVAC systems and other equipment to keep the room safe and working in real-world conditions.
Building a cleanroom means putting together parts like walls, windows, doors, ceiling grids, and fan filters to bring in clean, filtered air. Sometimes, extra systems like special HVAC units, airlocks, or pass-through chambers are added. All these parts work together to keep the cleanroom clean and safe.
1. Measure the Space
Taking exact measurements is very important for cleanroom installation. Even small mistakes can cost a lot of time and money. If something doesn’t fit, extra materials or changes might be needed. Measurements must also match the supplier’s plans to avoid problems. Technology can fix small mistakes, but big errors, like being off by more than three inches, might mean redoing parts of the work, which takes more time and adds to the cost.
If you want to turn a room into a cleanroom, you need to make sure it’s big enough to hold all the equipment and systems it requires. For example, a warehouse space being changed into a cleanroom needs enough room for everything to fit and work properly. You can check this by looking at the building’s blueprints or the supplier’s equipment details.
Working with expert cleanroom builders and taking very careful measurements is important. It helps prevent mistakes that can cost a lot of money and time to fix. This also makes sure the cleanroom works properly and follows all the rules it needs to meet.
2. Cleanroom Construction Tools
Building a cleanroom needs special tools to do the job right and quickly. These tools help with measuring, cutting, putting together, and installing the parts that make up the cleanroom. They make sure everything fits and works as it should. Common tools used in the process include:
- Tape Measure
- Laser Tape Measure
- Chalk Line
- Screwdrivers (manual and electric)
- Pliers (various types)
- Adjustable Crescent Wrench
- Power Drill with Assorted Bits and Attachments
- Wrenches (different sizes)
- Nail Punches or Center Punch Tools
Using strong, reusable tools for building a cleanroom is a smart way to save money. These tools last a long time and can be used over and over again. Workers can also share the tools instead of each having their own, which helps cut costs on buying and replacing them.
Cleanroom tools can be bought from local hardware stores or online shops, like Bunnings. Getting good, strong tools that last a long time helps builders work smoothly and quickly. This also ensures that the cleanroom is built well and stays on track.
3. Purchase Equipment and Materials
Once everything is measured and planned, suppliers order the materials needed to build the cleanroom. These materials can be sent to the construction site or another place first. Sending them straight to the site is usually better because it keeps things organised and makes sure the materials are ready and stored correctly when needed.
When materials arrive for building a cleanroom, they are placed in a loading area, like a yard or dock. They might stay there for a while or be moved to a safer storage spot, like a warehouse. Some suppliers charge more to deliver materials straight to the site, but ordering a lot at once (buying in bulk) can lower costs. Big orders often get better prices, which helps save money during construction.
Before building a cleanroom, materials are often stored for 4-6 weeks. This gives enough time to get everything ready and make sure the project doesn’t face delays. Big companies usually get better deals on materials because they buy more, and suppliers want to keep them as customers.
4. Organise Storage Area for Materials
Before building a cleanroom, the off-loading area needs to be prepared. This means clearing the space and moving other items to storage so new materials can be placed safely and neatly. For heavy materials, tools like forklifts or pallet jacks are helpful because they make it easy to move big loads.
After clearing the off-loading area, it’s important to keep it neat and ready for the next deliveries. Staying organised prevents delays and makes sure materials are easy to find when needed. This helps the cleanroom construction go smoothly and stay on schedule.
Tips for Efficient Off-Loading Area Preparation:
- Clear and Organise the Space Early
- Use Appropriate Equipment for Heavy Materials
- Designate Storage Areas
- Ensure Easy Access for Future Deliveries
- Coordinate Deliveries with Installation Schedule
Steps in Building and Maintaining a Cleanroom
Once all the materials and equipment are at the site, the next step is to carefully put everything together. Each part needs to be assembled the right way to make sure the cleanroom works properly. After the project is complete, it’s important to take care of the cleanroom and keep it in good condition so it stays safe and useful for a long time.
Below are the steps to guide you through the cleanroom construction process:
Install Flooring
The flooring in a cleanroom is very important. It has to be strong enough to handle chemicals often used there and easy to clean. This helps keep the cleanroom safe and working the way it should.
Cleanroom floors are usually made of concrete or interlocking tiles, depending on what’s needed. Interlocking tiles are often used in modular cleanrooms because they’re easy to replace and simple to clean. Once the floor is installed, it needs to be strong enough to handle heavy equipment without getting damaged or slowing things down.
Key Considerations for Cleanroom Flooring:
- Durability: Make sure the flooring can handle the chemicals and wear specific to your cleanroom’s activities.
- Ease of Cleaning: Pick easy-to-clean materials to lower contamination risks and maintenance.

- Prevention of Hazards: Protect employees and equipment from damage due to equipment failure or malfunctions.
Set Up Plumbing and Piping
A cleanroom’s plumbing system is important because it helps get rid of waste and also manages water and air systems. The pipes and drains need to be built just like the project plans say to make sure everything works properly and safely.
Cleanroom pipes need to be insulated so they don’t have problems when temperatures change. It’s also very important to put in pipes without any leaks. This keeps the system safe and avoids contamination that could cause serious issues.
Install Sanitation Systems
Chemicals and disinfectants are used in cleanrooms to keep everything sterile and stop contamination. Plumbing connections need to be set up so workers can easily clean and sanitise the space every day, making sure the cleanroom installation stays safe and ready to use.
Cleanrooms might need extra features like drains to handle waste, scrubbers to clean surfaces, safety eyewear to protect workers, sticky mats to stop dirt from coming in, steam generators for deep cleaning, and PPE to keep everyone safe. It’s important for project plans to list all the equipment needed so the cleanroom stays clean and safe to use.
Install HVAC Systems
HVAC systems are put in cleanrooms to control the environment. They use air conditioning, fans, and heaters or coolers to keep the temperature and airflow just right. These systems need the right exhaust and intake points, as planned in the cleanroom design, to make sure the air moves properly and the cleanroom stays in perfect condition.
Test HVAC Systems
After the HVAC systems are set up, workers check how air moves in and out of the cleanroom. They use a device that measures how fast the air is flowing. This step is important to make sure the cleanroom has the right airflow to stay clean and work as it should.
Measuring airflow in a cleanroom is important to make sure the fans are set up correctly. This helps keep the air at the right humidity and moving as it should. The process takes about 15 minutes and shows that everything is working to keep the cleanroom safe and controlled.
Key Airflow Verification Steps:
- Use Air Velocity Devices: Measure airspeed to ensure proper airflow and ventilation.
- Confirm Fan Configuration: Ensure fans are correctly set up to maintain optimal conditions.
- Check Humidity Control: Verify that the airflow is sufficient to maintain the desired humidity levels.
Complete Testing and Maintenance
After the cleanroom installation is done, employees take over and run tests to make sure everything works properly. They also take care of the cleanroom by keeping it clean and making sure all the systems are working as they should. These steps are important to keep the cleanroom running smoothly and doing its job effectively.
Regular checks are done in cleanrooms to make sure all systems are working and everything stays clean. Daily and even hourly cleaning with vacuums is important, along with hiring a special cleaning service. These steps help keep the cleanroom in top shape so it stays safe and ready to use.
Keeping a cleanroom free from trash and dirt is very important to stop contamination. Rugs or sticky mats at the doors help catch dirt before it gets inside. If something isn’t working right, it should be fixed immediately to prevent bigger problems or damage.
Perform Commissioning Tasks
Commissioning tasks are important to make sure a cleanroom works properly and meets all the rules. These tasks include testing and re-testing systems like HVAC, cleaning equipment, and lights to check that they work well. Staff are also trained on how to take care of the cleanroom to keep it in great condition.
Part of getting a cleanroom ready involves turning on switches, testing electrical equipment, and starting the power to make sure everything works. This process usually takes less than an hour and helps get the cleanroom ready for everyday use.
Key Commissioning Steps:

This includes checking that emergency lights and other important electrical equipment work properly. Regular tests, done several times a day, help keep the cleanroom safe and running reliably.
Tests in cleanrooms can be done by the workers who take care of the facility or by outside companies, depending on how tricky the systems are. Regular checks are important to stop dangers and make sure the cleanroom stays a safe place to work.
Inspect Facility
Given the critical nature of a cleanroom, regular inspections are essential to maintain compliance with the initial construction specifications and ensure optimal performance. Inspections should be conducted every six months to verify that the space is operating according to the established standards and that all systems continue to function correctly.
Cleanroom design guidelines help owners know what to check and how to do it during inspections. By following these guidelines, they can make sure the cleanroom stays clean and safe for everyone.
How to Reduce Cleanroom Fan Filter Maintenance Costs?
Minimising the maintenance and replacement costs of fan filter units (FFUs) in cleanrooms is crucial for long-term efficiency and budget control. Proper planning and strategic choices can significantly extend the lifespan of these units, reduce downtime, and lower overall costs. Here are a few effective tips to help minimise these expenses:
- Use Prefilters
Prefilters catch big particles before they reach the main filters. This protects the main filters and helps them last longer. - Choose Easy-to-Replace Filters
Use room-side replaceable filters. These are easier to change without messing up the cleanroom, saving time and keeping things clean. - Keep Things Clean During Construction
Use sticky mats, shoe covers, and non-marking ladder feet when building or fixing the cleanroom. This stops dirt from getting in and causing problems. - Design for Easy Cleaning
Build smooth walls and round corners. These are easier to clean and stop dirt from piling up, which reduces cleaning costs.
Conclusion
The cleanroom installation process is vital for creating a controlled, safe, and efficient environment across industries.
