Fan Filter Unit, WhisperFlow, RSR, 2'x2', HEPA, 240 V, Powder-Coated Steel, Terra Universal (CAT#: STEM-C-0012-ZJF)

Highlights

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.
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.
Protect Against Contaminants and Pathogens: HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores.

Cat Number: STEM-C-0012-ZJF

Application: It is used to provide steady laminar flow stream of HEPA filtered air to the area below the mounted unit for cleanrooms. Low-profile design is ideal for cleanrooms with limited ceiling space.
