50Hz Electric Fan Filter Unit, Certification : CE Certified

Fan Filter Units direct a vertical laminar flow of filtered air downward through the enclosed cleanroom area. Each includes a 1100 CFM impeller blower (rated at 90 FPM with filter load) mounted in an MS housing with a plenum design that ensures ample air velocity across the entire face of the filter. A HEPA (high efficiency particulate air) filter installed inside the housing is rated 99.99% efficient at 0.3um particles. The filtration medium consists of micro porous polyurethane mini-pleats held in place by strong, rigid plastic separators that keep the medium from nesting. This design channels airflow with optimal efficiency to reduce resistance. The filter is sealed into the sturdy powder-coated steel frame with a fire-retardant, non-outgassing adhesive. Power to the Fan Filter Units is controlled by a master ON/OFF switch located on the cleanroom control panel. All 120VAC units and 220VAC, 60Hz units are UL listed. CE-marked models are available for 220VAC, 50Hz operations.
