CAP116 Vertical Flow Fan Filter Units are decorative, self-contained, vertical-flow filter units designed to be suspended from a ceiling or hung off a wall. Front servicing of filter, blower and lights make these filter units ideal for applications where ceiling access is not possible. Prefilters can be located on the top or front of the unit.


Standard HEPA filter provides 99.99% efficiency on particles 0.3 microns are larger. Optional ULPA filters provide 99.999% percent efficiency on particles as small as 0.12 microns. Filters are removable through the front panel of the unit for easy maintenance.


Air flow velocity is factory-set in accordance with Federal Standard 209E (90 ± 20 FPM). Blower/motor assemblies are sized to provide proper air flow with a minimum 50% increase in HEPA filter pressure drop. This ensures years of reliable service from your custom fan filter unit without changing the HEPA filter.

Blower/Motor Assembly

CAP116 custom cleanroom fan filters utilize PSC direct drive motors with dynamically balanced blower wheels. Each blower/motor assembly is double vibration isolated from the cabinet to provide exceptional vibration control. The motor itself is vibration isolated from the blower via multiple shear rubber isolation mounts. Assembly is further vibration isolated from the fan filter unit itself by a second set of isolation mounts. A flexible duct connection between the blower and metal filter supply plenum also serves to reduce vibration. All blower/motor assemblies feature speed controls mounted on the inside which can be adjusted to compensate for extra pressure drop caused by loading or contamination buildup on the HEPA filter surface.
