Fan Filter Units & Terminal Units for Cleanrooms
Air changes and filter efficiency are critical components of cleanroom performance. Fan filter units (FFUs) and terminal units can be used independently or in combination to meet the most stringent cleanroom requirements.
HEPA and ULPA Fan Filter Units
Fan filter units (FFUs) are self-contained units that combine a fan and a filter. FFUs move and filter air, creating a laminar flow that directs it in a steady, unidirectional flow, independent of the HVAC system. In addition, there is a potential reduction in AHU size and ductwork requirements.
HEPA and ULPA Terminal Units
Unlike FFUs, terminal units do not have built-in fans; they rely on the cleanroom’s HVAC system to provide airflow. The air, having been pre-filtered by the HVAC system to remove larger particles, passes through the terminal unit’s HEPA or ULPA filter to remove the smallest contaminants before entering the cleanroom.
- May be combined with FFUs for advanced cleanroom designs

Plenum Ceiling Systems
Suitable for the most critical cleanroom environments, plenum ceiling systems eliminate the need for field-built ducts and duct collars while reducing pressure drop. Plenum modules have the same benefits as flush ceiling grids, including integrated lighting and fire protection and excellent performance.
- Plenum Modules are Available in Sizes Up To 8’ x 24’
- Able to withstand high point loads with minimum deflection
- Plenums can support recirculation air handlers, live loads, and other accessories.
- Maintenance access to fan modules is made easy via walkable top skins.
- Provides Direct Support for Recirculation Air Handlers
- Plenum Module Eliminates the Need for Field-Built Plenums
- Shared Air Openings to Adjacent Plenums
- Plenum Modules are Suspended from Structure or Custom Floor Mounted Support Structure can be

Fan Filter Units and Terminal Units for Modular Cleanroom Wall Systems
Our FFUs and terminal units can be integrated with either structural or seamless-style cleanroom construction.
Structural Solutions
Structural systems can be constructed without tying into building infrastructure. These structures can be configured to support mechanical equipment & accommodate expansion; helping future-proof your investment.
Seamless Solutions
Seamless modular wall systems provide the highest levels of sterility and ease of cleaning. The seamless nature of these walls significantly reduces the risk of contamination and particle accumulation.
