Fan Filter Unit, Explosion-Proof, Reverse-Flow, 2'x4', ULPA, 120 V, Stainless Steel, WhisperFlow, BioSafe®, Terra Universal (CAT#: STEM-C-0084-ZJF)

The Explosion-Proof Fan Filter Unit (RSR) 6601-24-UEVSS manufactured by Terra Universal provides a steady laminar flow stream of ULPA filtered air to the area below the mounted unit.
Make the room into a negative pressure isolation room or airtight room.
Explosion-proof FFU meets NEC requirements for Class I/Class II, Division 1 Hazardous locations.
The motor mounted in cast iron explosion-proof enclosures is sparkless.
The unit is mounted into the ceiling bay to remove submicron particles and make exhaust safe.
Room-side replaceable fan filter units minimize cleanroom out-of-service time.
Explosion-Proof Design:
Explosion-proof motor meets NEC requirement for Class I Group C and D, Class II Group F and G, Division 1 hazardous locations.
All wiring is securely embedded in packed rigid conduits to meet class I/II requirements.
All wiring of the explosion-proof system shall be done on site by a licensed electrician according to local regulations to ensure the safety and effectiveness of the explosion-proof protection.
FFU Design:
All-304 stainless steel BioSafe® frame and parts are easy to clean, hard and highly resistant to corrosion.
Internal baffling plate and diffuser panel make the air flow quiet and even.
FDA-approved silicone sealant has good sealing, high safety and durability..
Ultra-Low Particulate Air (ULPA) Filter: 99.999% efficient at 0.12µm particle diameter. Assembly was not completed at the time of shipment to prevent damage.
Medical grade filters are leak tested in accordance with IEST standards and meet UL 900.

Diffuser Panel Promotes Air Flow Uniformity and Protects Filter Integrity: Unlike other manufacturers, Terra's FFUs use a unique perforated panel like a shower head beneath the filter, to protect the filter and make laminar air flow more uniform by preventing 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.
Non-Sparking Direct-Drive Motor: Explosion-proof motors use a non-sparking polypropylene fan and cast-iron brackets connected to the heavy-duty rolled steel frame.
Gel-Filled Channel on Room-Side Replaceable Filter: Gel-filled channel on room-side replaceable filter creates a closed passageway, so it allows the filter to be changed easily, safely and quickly during the operation of the fan filter unit.
Explosion-Proof Junction Box: The reinforced junction box can withstand and contain the explosive reaction in the conduit.
Long Running FFU Motors: Terra's filter fan unit motors can operate continuously for up to 5 years if the filter is changed frequently.
Easy-Release Filter Clamp on Room-Side Replaceable FFU: Easy-release clamps are rotated to release the filter, simplifying filter servicing without stopping the cleanroom.
Explosion-Proof Power Switches: UL-rated explosion-proof switches are connected to the circuit by special conduit. All electrical components are sealed to eliminate potential combustion hazards.
Explosion-Proof Potted Fittings: Conduit is filled with an expanded cement mixture to isolate the explosion-proof components from potential ignition sources; 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 wire frame embedded in the prefilter to prevent sparks.
WhisperFlow Quiet Operation Reduces Distracting Background Noise: Noise can reduce concentration at work and even lead to safety accidents. Unlike other AC units with 70 dB of noise, Terra's WhisperFlow design has library-level noise levels. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).
Product Prices Honored Worldwide: The price of each Terra Universal product worldwide is the same as the web-listed price.
Multilingual Website Translator: Terra's website supports more than 80 different languages.
Catalog of CE-Marked Products: Terra offers over 1,700 CE-marked products configured for international voltage requirements.
