Explosion-Proof WhisperFlow™ Room Side Replaceable Fan-Filter Units allow filter changes without having to open the cleanroom ceiling | 6601-24A-URE displayed
Proper installation of explosion proof equipment is critical to maintaining the explosion-proof protection aspects of the system.
Customer must hard wire the motor/ffu in correlation to their specified voltage at time of installation
Therefore all wiring for explosion proof systems should be done in the field per local code by a licensed electrician.
Explosion-proof motor meets NEC requirement for Class I Group C and D, Class II Group F and G, Division 1 hazardous locations
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
NOTE:
Customer must determine if filter leak testing is required for their application. This unit is not leak rated. If a leak test is required, units leak-tested to meet ISO 14644-3 are optionally available.
All filter sales are final; returns cannot be accepted due to the sensitive nature of HEPA filters. Leak tested filters may qualify for limited replacement if a defect is identified upon delivery.

Features and Benefits
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.

Explosion-Proof 40W LED Light
UL-listed for Class I, Division 1 and 2, Groups C and D areas, this low profile LED light produces 3,600 lumens and operates from 120 to 277VAC, 50/60Hz. The heat-dissipating housing increases the efficiency and lifespan of the LEDs.
Explosion-Proof Power Distribution Module
Explosion-Proof Power Distribution Module (PDM) meets NEC code for a Class I/Division 1 hazardous location; includes all relays, breaks and other cleanroom electrical components
Challenge Port for Fan Filter Unit
Challenge port for Fan/Filter Units simplifies filter leak testing and connection of Filter Backpressure Alarm (shown with optional pressure gauge; must be ordered with FFU).
Safely Mount FFU’s Above Floor for Horizontal Laminar Airflow
The portable FFU base stand can be easily positioned to supply Class 100 horizontal laminar flow into a room or enclosure. It can also be positioned next to sensitive equipment/materials that are mounted close to the floor.
