Fan Filter Unit; WhisperFlow, RSR, 2'x4', ULPA, 120 V, Stainless Steel, BioSafe®
- Available ISO Ratings: ISO 4, ISO 5, ISO 6, ISO 7, ISO 8
- Customer must determine if filter system leakage testing is required for their application. This unit is not full seam welded. If a leak test is required, full seam welded units leak-tested to meet ISO 14644-3 are optionally available.
- Ultra-Low Particulate Air (ULPA) Filter: 99.999% efficient at 0.12µm particle diameter
- All-304 stainless steel BioSafe® housing, baffle plate, filter face grille, filter frame and impeller ensure optimal cleanliness and stand up to alcohol and other cleaning agents
- Room-Side Replaceable (RSR) design allows quick filter replacement from the inside of the cleanroom. Because it eliminates the need for roof access or breaching the cleanroom, an RSR model greatly reduces maintenance time and costs.
- Gel-sealed filter seats securely against a knife-edge on the fan housing
- Easy-open clips allow fast filter replacement from the room side without breaching the cleanroom ceiling
- Filter shipped uninstalled to prevent shifting in the mounting gel that could cause leaks.
- AC 3-speed blower motor
- FDA-approved silicone sealant
- Internal baffling plate and diffuser panel provide quiet uniform air flow across the filter face
- 1/4-20 UNC threaded inserts on corners to allow suspension by guy-wires
- MERV 7 pre-filter, 30% ASHRAE rated
- Low-profile design is ideal for cleanrooms with limited ceiling space
- Removable yellow power cord with 4-pin connector for easy installation to Terra cleanrooms (connector may be used with an optional wall plug adapter; or may be removed entirely to hard-wire the FFU)
- Filters are leak tested in accordance with IEST standards and meet UL 900
- See performance data and submittal sheets for additional information
- Optional Accessories:
- Challenge port kit
- Power plug adapter
- Stainless surface mount frame for installing FFU in ceiling without T-grid

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.
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.
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
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.
Full Range of Designs, Configurations! 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).
WhisperFlow Quiet Operation Reduces Distracting Background Noise 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).
