Fan Filter Unit

PS AIR TECH cleanroom fan filter units are self-contained devices that utilize HEPA or ULPA filters. We offer a full line of standard and custom fan filter units, with numerous options available to meet your specific cleanroom requirements.MAC 10 Original comes standard with the filter integral with the unit housing, requiring the unit to be removed from the ceiling grid to replace the filter.

The RSR unit has the filter sealed to the unit using the knife edge/gel seal construction, allowing the filter to be replaced from the room side. The RSRE unit has the added feature of allowing the motor blower and filter to be replaced from the room side.
