Fan Filter Unit; WhisperFlow, 2'x4', HEPA, 240 V, Powder-Coated Steel

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.

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.

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

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.

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

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
