Every cleanroom has a complex environmental control unit (ECU). This advanced technology can be adopted in nearly any space across different industries, despite the particular issues each one faces. ECUs are best suited to meet the unique challenges of various lab cleanroom applications, such as harvesting samples in medical tech labs, manufacturing semiconductors,  or preparing to send components to outer space.

Cleanroom ECUs ensure that the environment is sterile, controlled, and consistent so workers and machines in the cleanroom work productively and contamination-free. Air Innovations manufactures environmental control solutions for various cleanroom applications, which you can learn more about below.


Cleanroom classificationOur Cleanroom Environmental Control System Solutions

Air Innovations specializes in designing and developing environmental control systems. Environmental control units are devices used to regulate environmental conditions in a given space. Cleanroom monitoring systems are necessary to check and control variables such as temperature, contaminants, humidity, pressure, and flow rate so they meet the required parameters of the cleanroom. This ensures cleanroom manufacturing personnel and processes are effective and efficient.

At Air Innovations, our cleanroom control systems are the only fully integrated devices specifically designed for cleanroom applications. We can tailor our cleanroom control systems to meet our clients’ specific requirements for functionality, features, size, and more.


Key Environmental Control System Components

Environmental control systems have several components to ensure real-time monitoring and control of environmental variables. These aspects include particulate, temperature, humidity, air pressure, and microbial control.

Particulate Control

The presence of airborne particulates such as mold, pollen, and dust can contaminate the integrity of critical manufactured components, such as sensitive electro-optical components. Our environmental control units maintain ISO 14644 standards. Our low-grade high-efficiency particulate air (HEPA) filters can separate at least 99.97% of all airborne particulates 0.3 microns or larger. Ultra-low particulate air (ULPA) filters can remove 99.9997% of particles 0.12 microns or larger. The filters must be checked regularly and replaced as needed. The ECU also must distribute the air properly throughout the cleanroom to maintain cleanliness.

Temperature and Humidity Control

Temperature gradients and moisture can compromise the operation of sensitive electro-optical components and can result in contamination. Our cleanroom ECUs control both humidity and temperature since temperature determines the percentage of relative humidity (RH) at a given atmospheric pressure. This control system features components found in refrigeration systems as well as accurate sensors and controls.

Air Pressure and Flow Rate Control

Environmental control units maintain clean air and optimal temperature and humidity by changing or passing air within the cleanroom multiple times per hour. They can keep higher (positive) or lower (negative) air pressure inside the cleanroom depending on its specific requirements.

Microbial Control

Air Innovations’ environmental control units use microbial control to prevent airborne mold or bacteria from contaminating sensitive pharmaceutical or medical products. Ultraviolet germicidal irradiation (UVGI) is integrated into the air filtration system to kill microbes effectively.


Cleanroom HVAC

Air Innovations has a whole division dedicated to designing and manufacturing unitary and custom cleanroom HVACs. These HVAC systems use HEPA filters to eliminate fine particles such as microbes, dirt, and dust. This filtration keeps the cleanroom sterile for applications like pharmaceutical, medical, semiconductor, research, and compounding labs, which require a consistent, highly controlled environment.

Cleanroom HVAC solutions typically have a better air exchange rate than standard HVACs. Any HVAC system for cleanroom use must meet all relevant regulatory requirements for that application.

Our cleanroom HVAC products include the following:


  • Portable and lightweight
  • Fits enclosures up to 30 cubic feet in size
  • Quiet Operation
  • Cools and heats 5ºF below/above room temperature

  • Best in softwall, single-pass air


  • Tight temperature control as low as ±0.02°C
  • Humidification control to ±0.5% RH
  • Chilled water or DX-based systems
  • Computer-managed, system-wide control


Custom Cleanroom Environmental Control Units

Many cleanroom spaces have such unique environmental conditions they require custom ECUs that can accommodate those special requirements. These include operating environments, industry and regulatory standards, size constraints, efficiency requirements, or other application requirements.

Air Innovations is an industry leader in designing and manufacturing custom ECUs. Due to our industry-specific expertise, we can provide ECUs suitable for any environmental control demand. This customizability gives our clients the tools to keep their cleanrooms compliant with their performance requirements and industry regulations.

The custom-cleanroom-environment control units that we’ve built include systems for these applications:
