For instance, aseptic environments require walls that can be exceptionally cleaned to maintain high levels of cleanliness.
The floor of a modular clean room, like the walls, significantly impacts the room’s classification. It must be durable enough to endure frequent cleanings with various solvents and cleaners.
Common types of modular clean room flooring include:
Perforated raised flooring is designed to allow for contaminants and particulates to be removed from the room by the air circulation system as well as manage the heat load. The use of a perforated raised floor creates a more efficient environment for the air flow system.
There are several factors that govern a modular clean room ceiling since they must be capable of supporting a variety of equipment, which includes the lighting, air flow system, sprinklers, and various forms of small equipment. Ceilings for modular clean rooms consist of suspended panels that are locked or bolted together.
The ceiling material of a modular clean room is designed to be flexible and adjustable, accommodating the installation of venting, lighting, and filters without requiring changes to the orientation of the panels. The flush, smooth bottom surface allows for ceiling components to be installed anywhere without interfering with the grid.
A key feature of ceiling panels is their precise fit, with each panel securely connected to its adjoining panel using a fixed metal spline. Non-progressive ceiling panels are designed for easy disengagement, allowing for adjustments and removal as needed.
Ceilings are constructed from large sheets that are treated and cut into tiles. To ensure a tight seal, gaskets or other sealing methods may be used. During installation, the tiles are fitted closely to prevent ambient air from entering the clean room.
Just like other factors affecting a modular clean room, the choice of lighting plays a crucial role in the room's working conditions and overall operation. Lighting options include incandescent, fluorescent, and LED. In modular clean rooms, careful consideration must be given to how lighting is integrated, unlike in permanent clean rooms.
Lighting placement must be coordinated with the air supply system to minimize contamination. As the air supply system is installed in the ceiling, lighting fixtures need to be positioned around it to avoid interference.
Cost is an important consideration for the lighting system, as it impacts both the initial installation and ongoing energy expenses. Additionally, maintenance costs are a factor, since keeping light fixtures free of contaminants is essential. Clean room operations often involve precision instruments, which require high foot candle levels to ensure adequate illumination.
Types of lighting include:
The air filtration system is the most crucial component of a modular clean room, responsible for circulating highly purified air with minimal contaminant particulates. To maintain such stringent conditions, clean rooms utilize high-efficiency particulate air (HEPA) filters, which can remove 99.95% of airborne particles.
All the air that enters a clean room passes through one or more HEPA filters. For clean rooms that require greater efficiency, ultra-low particulate air (ULPA) filters are used that capture particles as small as 0.12 microns, which is one millionth of a meter.
In modular clean rooms, filtered air is introduced from overhead fans and exits through the floor or floor vents. In single-pass systems, air is drawn in through the ceiling and expelled outside. Conversely, recirculating clean rooms pull exhaust air back through the filtration system to be cleaned and reintroduced. A negative pressure design helps prevent contaminants from escaping the clean room and affecting external areas.
Laminar airflow systems utilize laminar hoods to maintain a steady, unidirectional airflow. These hoods direct air downward into the room and are constructed from non-shedding metals to avoid introducing contaminants. Laminar airflow systems are integral to the clean room's overall filtration setup.
Various features can be incorporated into a modular clean room to enhance control over contaminants and harmful particulates.
Pass Through Chambers – To avoid the need for workers to be constantly dressing and undressing to enter a modular clean room, pass through chambers are added that allow people outside the chamber to pass items to people on the inside. These are tightly sealed and only remain open for an instant.
Gowning Room – Though this may be listed as an extra component, gowning rooms are a common part of the clean room process since anyone who enters a clean room has to be properly covered and cannot get covered in the clean room. The gowning room is a controlled space for workers to put on their clean room gear.
Air Showers – An advanced and technologically innovative addition to modular clean rooms is an air shower, which is normally added to the airlock system. When a worker enters the air lock, a burst of filter air is blown at the employee to remove any potential contaminants that can be shaken off by a burst of air.
An essential aspect of clean rooms is the provision of a pollutant free environment with a low possibility of contaminants. All equipment, cleaning products, utensils, clothing, and any other materials must meet specific standards to keep the clean room’s ISO classification.

Building and testing a physical prototype of a clean room can be costly and time-consuming. Instead, engineers use CFD to simulate and analyze the clean room's components without needing the actual product.
CFD analysis involves studying fluid flow based on physical properties such as velocity, pressure, temperature, density, and viscosity—all of which are crucial for clean room performance. CFD software allows for the simultaneous examination of these factors to produce accurate data about the clean room's behavior and effectiveness.
Key aspects analyzed by CFD software for clean rooms include:
– Air Change Effectiveness: This simulation assesses the circulation patterns of air within the clean room and identifies areas that may be challenging to ventilate effectively.
– Contaminant Distribution: CFD analysis predicts how contaminants will disperse within a clean room and allows for tracking their movement. This data helps in forecasting potential risks to materials and personnel.
– Air Flow Efficiency: Proper air flow is crucial in clean room design as it can lead to significant issues if not managed correctly. CFD software helps identify air flow velocity, allowing engineers to adjust the room’s design to ensure uniform air distribution throughout the space.
Another important method for testing air flow in a clean room is through smoke studies, which help visualize airflow patterns. By introducing smoke into the clean room, its movement reveals the air flow dynamics. Smoke studies, also known as dynamic air visualization, are crucial for the qualification, maintenance, and ongoing monitoring of a clean room to ensure it remains free from contamination.
Smoke studies confirm that the air flow is properly directed through the high-efficiency particulate air (HEPA) or Ultra Low Particulate Air (ULPA) filters. Expertly trained professionals carefully select the type of smoke used in the test, as the physical properties of the smoke significantly impact the study results and the clean room’s qualification.

The demand for sterile environments has surged with advancements in technology, necessitating controlled and monitored conditions for the production of sophisticated instruments. While traditional clean rooms are crucial for handling sensitive materials, their permanent installation can be costly and may not be necessary for all scenarios.
Modular clean rooms offer a practical solution by bridging the gap between permanent clean rooms, which require extensive structural modifications, and temporary setups like plastic tents. These modular systems can be quickly and easily installed with minimal disruption, making them ideal for temporary or short-term applications where long-term commitment is not required.
The primary appeal of modular clean rooms lies in their rapid setup and construction. The installation process starts with a durable frame that supports prefabricated and custom-designed panels, allowing the clean room to be assembled in just a few hours. This efficiency means that a team can quickly access a controlled and monitored environment to start their projects. Equally impressive is the ease of dismantling: the clean room can be removed just as swiftly, leaving no trace of its presence.
Cost is often the primary concern when considering changes to manufacturing or testing processes. Typically, these adjustments involve significant mechanical and operational modifications that can be costly, require extensive planning, and disrupt workflow. In contrast, modular clean rooms offer a cost-effective solution. They are efficient, compact, and affordable to install and operate, avoiding the major expenses and disruptions associated with more permanent changes.
Maintaining equipment to ensure optimal performance can be costly and complex. For traditional brick-and-mortar clean rooms, any damage or issues typically require a shutdown for repairs and reclassification, which can be both time-consuming and disruptive.
In contrast, modular clean rooms offer a more flexible solution. If a component is damaged, it can be swiftly removed and replaced with minimal disruption to operations. Modular clean rooms feature moisture control, air filtration, and durable components that are easily replaceable and adaptable, ensuring continued efficiency and performance.
Manufacturers are increasingly focused on minimizing their environmental impact by implementing sustainable practices and policies. Modular clean rooms align with this goal by being fully reusable and adaptable. Each component of a modular clean room can be employed, removed, and repurposed without the need for new construction. Once installed, a modular clean room operates as an isolated environment, leaving no footprint on its surroundings.
When a modular clean room is no longer required, it can be dismantled and removed completely, leaving no trace of its previous presence.
While cost, construction, maintenance, and environmental impact are important factors in choosing a modular clean room, the primary benefit lies in its ability to create a controlled, contamination-free environment for observing, testing, and studying sensitive materials. Modular clean rooms start with a HEPA filtration system to maintain air purity. Their flexibility allows them to be easily adapted, modified, and reconfigured to meet evolving needs and conditions.
Labeling a modular structure as a clean room implies that it meets specific standards and certifications, including ISO certification, FDA approval, and EU regulations. Manufacturers of modular clean rooms strive to ensure their products comply with the stringent requirements set by major certification bodies. Maintaining the integrity of these standards is crucial, as the term "clean room" is reserved for environments that adhere to rigorous codes of cleanliness and operational precision.
Permanent buildings added to a facility depreciate over time, with their cost typically amortized over forty years. In contrast, modular clean rooms qualify for accelerated depreciation under IRS Section 179, allowing companies to amortize their cost over just six to seven years. This provides a significant tax advantage compared to permanent clean rooms, which spread their depreciation value over forty years. Despite offering comparable capabilities, modular clean rooms offer a more favorable depreciation schedule, making them a cost-effective choice for companies.
