Perkenalan produk

The gel-seal ULPA filter combines a high-efficiency mini-pleat microglass pack with a continuous fluid-gel trough in the aluminium frame. When the terminal housing's knife edge enters the gel, the compliant material surrounds small surface variations and forms a reusable sealing path without high gasket compression. The media pack is separately bonded into the frame with polyurethane, and protective grids shield both filter faces. This arrangement is widely used in cleanroom ceilings and fan filter units where a consistent perimeter seal must be achieved during repeated filter changes.

Fitur utama:

A continuous gel trough conforms around the housing knife edge and accommodates small flange irregularities.

The perimeter seal requires less compression force than a conventional dry gasket on a large panel.

Separate media-pack potting isolates the filtration seal from the serviceable gel channel.

Rounded aluminium corners and uninterrupted gel continuity reduce vulnerable transitions at frame joints.

Kekhawatiran produk pelanggan

A very high-efficiency terminal filter can still fail its purpose if the large perimeter seal is uneven or difficult to reproduce after replacement.

A dry gasket needs excessive clamping pressure to seal a large ceiling panel.The knife edge displaces compliant gel and forms a continuous seal with low closure force.

Small housing flange irregularities create isolated bypass paths.Fluid gel flows locally around the knife edge and fills minor surface variations.

Gel migration contaminates the visible filter face.A correctly sized enclosed trough retains the selected polyurethane or silicone gel within the frame perimeter.

The seal is broken when the panel is removed for service.The gel can close around the knife-edge withdrawal path when handled within its service limits.
