Item # AT-2000, AT-2000 Fan Filter Module



Atmos-Tech AT-2000 fan filter units are designed to be used in a standard or cleanroom ceiling system. The motorized impeller provides a lower profile than units with larger centrifugal blowers, but can still handle an additional .125" external static pressure. The filter element is individually scan tested to ensure leak free operation. The AT-2000 is available in 95%, 99.99% and 99.9995% efficiencies and varying filter pack depths. The standard unit is available in nominal 2' x 4' only however custom sizes are available.

The unit is available with an integral white powder painted expanded metal face screen as standard and optional perforated or expanded stainless steel or perforated anodized aluminum. Each unit comes with a variable speed control accessible by either room side or from above, also option of disposable pre-filter or duct collar. The unit is sized to deliver 720cfm to twice the initial static pressure of the clean HEPA filter. The AT-2000 is also available with a room side replaceable filter element that uses an upstream gel to ensure a positive seal.
