EQUIPMENT OVERVIEW
The AstroFan
™
EC FFU (Fan Filter Unit) utilizes a state of the art Electronically Commutated (EC)
Motor and backward-curved, plastic Blower Wheel assembly to provide the desired airflow through a
HEPA/ULPA filter at an industry-leading efficiency and reduced sound level.
The AstroFan EC FFU is available in Aluminum or Stainless Steel options and as either a Top Side
Serviceable (TSS) or Room Side Replaceable and Serviceable (RSR) configuration, white powder
coat finish also available. For TSS, the AstroFan EC FFU housing sits on top of the HEPA/ULPA filter
frame. For RSR, the housing sits on top of an RSR Filter Adaptor Frame (Extruded Aluminum), and
the RSR Filter is installed from the room side.
AstroFan EC FFUs can be supplied with round duct inlet collars or with a prefilter frame. The latter
is ideal for incorporating AMC (Airborne Molecular Contamination) filters. All units offer universal
mounting via wire or rod suspension for use in a T-Bar grid ceiling, as well as a variety of grille options
and insulation.
AstroFan EC FFUs are available in many configurations, sometimes with custom features. Please
reference order specific data sheets and/or submittal drawings for more information.
