Fan Filter Unit;Explosion-Proof, RSR, 2'x2', ULPA, 120/240 V, Stainless Steel, WhisperFlow
- 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.
- Includes FDA-approved silicone sealant (specify acrylic urethane or other required sealant type when FFU is ordered)
- ULPA Filter: 99.999% efficient Ultra-Low Penetration Air, rated at particles 0.12µm diameter, shipped uninstalled to prevent damage during shipping
- All wiring embedded in filled, rigid conduit in accordance with Class I/II requirements
- Motor: 1 Speed direct-drive, 0.25HP, 1140 RPM, fan-cooled
- Proper installation of explosion proof equipment is critical to maintaining the explosion-proof protection aspects of the system. Therefore all wiring for explosion proof systems should be done in the field per local code by a licensed electrician.
- Customer must hard wire the motor/ffu in correlation to their specified voltage at time of installation
- Explosion-proof motor meets NEC requirement for Class I Group C and D, Class II Group F and G, Division 1 hazardous locations
- 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.
- 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
- 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
- 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
- Stainless surface mount frame for installing FFU in ceiling without T-grid
- 12" ducted inlet connection adapter
- Replacement filter
- Eye bolt package
- Pre-filter safety cover, for CE conformance

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.
