Fan Filter Unit, Reverse-Flow, RSR, 2'x2', HEPA, 120 V, Powder-Coated Steel, WhisperFlow, Terra Universal (CAT#: STEM-C-0089-ZJF)

The WhisperFlow® Reverse-Flow Fan Filter Unit 6601-22B-HVR manufactured by Terra Universal provides a steady laminar flow stream of HEPA filtered air to the area below the mounted unit.
Make the room into a negative pressure isolation room or airtight room.
Dust generated during maintenance or construction is also well removed by filter exhaust systems.
The unit is mounted into the ceiling bay to remove submicron particles and make exhaust safe.
Medical grade filters are leak tested in accordance with IEST standards and meet UL 900.
Accurate and complete airflow control can be achieved by PSC variable spee+B42:B56d motor.
Low-profile design is compact and takes up less space, ideal for cleanrooms with limited ceiling space.
Threaded (1/4-20 UNC) inserts on corners make the unit easy to hang and mount.
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 guarantee the convenience and soundness of the unit's installation to cleanrooms.
Connect the optional duct collar attachment to the duct to ensure safe venting outside the room.
FDA-approved silicone sealant has good sealing, high safety and durability. 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 inside the room so that filters containing potentially hazardous air pollutants can be removed without contact. RSR design and easy-open clips make it possible to replace the filter fast and convenient from inside the room without damaging the clean room, reducing maintenance time and cost.
Gel-sealed filter seats rest firmly against the blade on the fan housing.
Filter shipped uninstalled to prevent leakage caused by movement of the mounting gel.
Dust Collector Pan:
Removing the collector pan with accumulated dust particles easily from the filter for cleaning and maintenance will prevent contaminants from re-entering the cleanroom.
For applications involving toxic fumes or biohazards, filter disposal and replacement can be safely achieved through seamless integration of the module with the BIBO system.

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.
COVID-19 Infection Control: Terra's ceiling-mounted reverse-flow ducted fan filter units can convert the room into a negative pressure isolation room.
Dust Collector Pan Helps Prevent Contaminants from Re-Entering Cleanroom: Removing the collector pan with accumulated dust particles easily from the filter for cleaning and maintenance will prevent contaminants from re-entering the cleanroom.
Complete Project Transparency: Terra is dedicated to complete transparency on project status, shipment tracking, and installation scheduling.
Wide Selection of Global Shipping Options: Terra offers a broad range of global shipping services including door-to-door and white glove delivery.
Network of International Reps: Terra Universal has an international network of more than 20 local sales reps trained to provide comprehensive service for all Terra Universal's products.
