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.

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.

Easy-Release Filter Clamp on Room-Side Replaceable FFU

Easy-release clamps rotate to release filter on Room-Side Replaceable Fan Filter Units, simplifying filter servicing without the need for a 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).

Protect Against 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

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.

Durable Powder Coating Finish

Terra’s durable powder coating formulation exceeds the ASTM and ISO paint standards for hardness, thickness, humidity resistance, gloss and impact testing.
