Product Details
  • Available Certified ISO Grade Designs: ISO 6, ISO 7, ISO 8
  • Exhaust flow fan filter units convert any room into a negative pressure isolation/containment room
  • Filtered exhaust system also ideal for containing dust generated during maintenance or construction
  • Mounts into ceiling bay to remove sub-micron particles and provide safe exhaust
  • Medical grade filters are leak tested in accordance with IEST standards and meet UL 900
  • PSC variable speed motor provides precise, fully adjustable airflow control
  • Performance Data and Submittals
  • Low-profile design is ideal for rooms with limited ceiling space.
  • 1/4-20 UNC threaded inserts on corners allow suspension by guy-wires.
  • High Efficiency Particulate Air (HEPA) Filter: 99.99% efficient at 0.3µm particle diameter.
  • Backward-curved fan optimizes airflow efficiency.
  • Removable yellow power cord with 4-pin connector provides 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).
  • Optional duct collar attachment allows connection to ducting for safe exhaust outside of room.
  • FDA-approved silicone sealant without harmful chemicals seals inside housing to prevent air leakage.
  • Room-Side Replaceable (RSR) Filters 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
  • Includes:
  • Dust collector pan
  • (1) MERV 7 pre-filter (30% ASHRAE rated)
  • See performance data and submittal sheets for additional information.
  • Optional Accessories:
  •           Power plug adapter
  •           Stainless steel surface mount frame for installing FFU in ceiling without T-grid
