Low sound level at desired air flow
Optional Energy Efficient Low Watt Motor
The Abtech Fan/Filter Module is designed to fit a standard 2' x 4' ceiling opening.
At 90 FPM, the typical noise level is 50 dba.
Supply air passes through a 20" x 20" x 1" pleated type pre-filter rated at 30% ASHRAE efficiency.
The blower is a direct drive, forward curve blower. The standard motor is a 1/3 hp, 115V, 60 hz, single phase, permanent split capacitor with thermal overload protection. Other voltages are available.
Each module is equipped with a solid state variable speed control with RFI suppression and a fused on/off switch installed in a 2" x 4" junction box mounted to the prefilter frame. The module is then ready for the end-user to provide electrical hook-up.
A one piece plenum is fabricated from 20 gauge steel with a white powdercoated finish. Four (4) seismic clips are provided at all top corners.
Final filtration is a standard HEPA filter, 99.99% efficiency @ .3 micron or larger. A white epoxy grille with a diamond pattern protects the filter. HEPA filters are scan tested at the factory, leak thresholds according to IES-RP-CC001.3.
