مقدمة المنتج

This filtered floor-standing model retains the threshold-free cart path but adds a motorized HEPA unit inside the cabinet. Air recirculates at 375 CFM through perforations in the inner side panels and a 99.99% HEPA stage. It serves larger parts and wheeled loads that need more protection than the passive standard cabinet, while remaining distinct from a high-velocity cargo air shower.

الخصائص الرئيسية

Filtered cart transfer

Active recirculation helps control airborne particles around wheeled loads during the closed-door interval.

Side-return airflow path

Perforated inner panels provide distributed return openings without adding a raised transfer floor.

Dedicated 120 V fan unit

The listed 0.83 A motorized filter package can be planned as a discrete cleanroom utility load.

Applications

For carts, large component kits and production fixtures entering cleanrooms where the transfer enclosure should actively recirculate filtered air. Confirm that 375 CFM is appropriate for the selected chamber size and load blockage, and preserve service clearance for fan and filter replacement.

Solutions for Your Application

Passive cart transfer allows loose airborne particles to remain around the load before the clean-side door opens.Use the internal HEPA recirculation unit during a controlled closed-door dwell period to reduce the particle burden in the chamber air.

A filtered chamber may become ineffective when carts block the side returns.Size the clear width around the largest cart so both perforated return panels remain open and accessible for cleaning.

الخيارات المتاحة

Define chamber dimensions, control sequence, interlock, door windows and mounting frames. Plan filter access, replacement route, alarm contacts and the closed-door recirculation interval as part of the operating procedure.
