Features and Benefits

Quick-Connect Fittings

FFUs and lights can be easily added as cleanrooms requirements change, or disconnected for maintenance, without the need to run additional power lines or involve an electrician.

Non-Sparking Direct-Drive Motor

Explosion-proof motors use a non-sparking polypropylene fan and cast-iron brackets attached to the heavy duty rolled steel frame

Gel-Filled Channel on Room-Side Replaceable Filter

Gel-filled channel on room-side replaceable filter forms a tight seal against knife edge on fan housing, allowing fast, simple filter replacement from inside the cleanroom without the need for costly cleanroom shut-down.

Air Flow Uniformity

Unique WhisperFlow® FFU baffling system and anodized diffuser plate promote uniform air speed across the filter face.

Full Range of Designs, Configurations!

WhisperFlow® FFFUs come in all styles: room-side replaceble, all-stainless steel, HEPA or ULPA filtration, EC energy-saving fans, reverse flow and more (shown: vapor filtration module with UV sanitation lamp).

Eliminate Contaminants and Pathogens

HEPA and ULPA filters capture many bacteria, viruses, and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures

COVID-19 Infection Control

Terra’s in-stock ceiling-mounted reverse-flow ducted filter fan units convert any space into a negative pressure isolation room

Long Running FFU Motors

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.
