Features and Benefits

>

Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity

Unlike other manufacturers, Terra’s FFUs include a unique perforated panel beneath the filter, acting as a shower head, to guarantee filter protection and laminar air flow uniformity, which prevents localized air swirling, particle build-up and turbulence.
>

Protect Against Contaminants and Pathogens

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures
>

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.
>

Explosion-Proof Power Switches

UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points.
>

Explosion-Proof Potted Fittings

Conduit is filled with an expanding cement mixture to isolate explosion-proof components from potential sources of ignition; explosion-proof fittings meet requirements of NEC for Class I, Division 1 hazardous locations.
>

Pre-Filter Grounding Clip

A grounding wire connects the body of the Explosion-Proof FFU to a metal wireframe embedded in the pre-filter as a safeguard against sparking.
>

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
>

Explosion-Proof Junction Box

The reinforced junction box of the explosion-proof fan filter unit is built to withstand and contain an explosive reaction within the conduit system.
>

Airflow Uniformity Improves Laminar Flow

Non-uniform air speeds produce turbulence that can recirculate particles into the air stream. Unique WhisperFlow® FFU baffling system and anodized diffuser plate promotes uniform laminar airflow to minimize turbulence and effectively carry away contaminating particles.
>

Network of International Reps

Terra employs an international network of more than 20 local sales reps trained to provide comprehensive service on Terra's complete catalog of products
