Product Details
- Available ISO Ratings: ISO 4, ISO 5, ISO 6, ISO 7, ISO 8
- Exhaust flow fan filter unit convert any room into a negative pressure isolation/containment room
- Explosion-proof FFU meets NEC requirements for Class I/Class II, Division 1 Hazardous locations
- Non-sparking motor, mounted in a cast-iron, explosion-proof housing
- Mounts into ceiling bay to remove sub-micron particles and provide safe exhaust
- Minimize cleanroom service downtime with room-side-replaceable (RSR) fan filter units
- 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 embedded in filled, rigid conduit in accordance with Class I/II requirements.
- NOTE: 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.
- FFU Design:
- All-304 stainless steel BioSafe® housing, baffle plate, filter face grille, and filter frame 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 (6 mm) -20 threaded holes in top corners accommodate eyebolts to facilitate installation using suspended guy wires (order eye bolt package separately).
- FDA-approved silicone sealant without harmful chemicals seals inside housing to prevent air leakage (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.
- Medical grade filters are leak tested in accordance with IEST standards and meet UL 900.
- See performance data and submittal sheets for additional information.
- NOTE: Because filters are delicate and subject to damage during handling, all filter sales are final; no returns can be accepted.
- Room-Side Replaceable (RSR) Filter for Bag-in/Bag-out (BIBO) Replacement:
- RSR designs allow quick and safe Bag-in/Bag-out (BIBO) filter replacement from the inside of the room for contact-free removal of filters with potentially hazardous airborne contaminants. Because it eliminates the need for roof access or breaching the cleanroom, an RSR model also greatly reduces maintenance time and related 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.
- Dust Collector Pan:
- Collector pan accumulates dust particles that dislodge from the HEPA filter, preventing contaminants from re-entering the cleanroom. Collector pan is easily removed for cleaning or maintenance.
- For applications involving toxic fumes or biohazards, module seamlessly integrates with bag-in/bag-out system for safe filter disposal and replacement.
- Optional Accessories:
- Stainless steel surface mount frame for installing FFU in ceiling without T-grid.
- 12" duct adapter for connection to safe exhaust outside of room.
- Top safety cover, for CE conformance.
- Replacement filters.
- Eye bolt package for cable suspension.
- Includes:
- (1) Dust collector pan.
- (1) MERV 7 filter (30% ASHRAE rated), 19.5" x 19.5" x 7/8" thk.
