Perkenalan produk

The cleanroom HEPA terminal housing forms the final sealed transition between a central air-supply duct and the cleanroom. Its fully welded steel plenum accepts a top or side collar, while an internal clamping frame holds a HEPA or ULPA panel against a gasket or gel knife edge. A hinged or quick-release room-side diffuser provides access to the filter, pressure port and upstream challenge connection. Because the module contains no fan, airflow is governed by the upstream air-handling system and an optional inlet damper, making it well suited to ducted pharmaceutical, laboratory and healthcare ceilings.

Fitur utama:

Fully welded plenum seams create a continuous pressure boundary between the duct collar and filter seat.

Top, side-round or side-rectangular inlet positions accommodate different ceiling-clearance conditions.

Room-side clamps retain the filter evenly and allow replacement without removing the terminal box.

Interchangeable perforated, swirl or adjustable-nozzle faces adapt the discharge pattern to the room layout.

Kekhawatiran produk pelanggan

A terminal filter box must prevent bypass leakage, fit restricted ceiling space and remain serviceable without disturbing the supply duct.

Folded or spot-welded plenum seams can leak unfiltered supply air around the final filter.Continuous welded seams maintain a sealed pressure path from the duct inlet to the filter seat.

A centred top collar conflicts with structural members or shallow ceiling services.Alternative top, side-round and side-rectangular connections allow the plenum to fit the available space.

Uneven filter clamping leaves local gaps around a gasket or gel channel.Multiple room-side retaining points apply balanced compression around the complete frame.

One fixed diffuser pattern causes draughts or poor room mixing after a layout change.Replaceable front plates provide perforated vertical, swirl or adjustable radial discharge patterns.
