상품 소개

The knife-edge HEPA filter incorporates a thin continuous blade into the extruded-aluminum frame rather than carrying the gel on the filter itself. When the panel is lowered into a cleanroom ceiling grid or terminal housing, this blade enters the receiving gel trough and forms a fluid seal around all four sides. The mini-pleat media pack is potted within a separate frame cavity, and protective faceguards shield the filter during common-plenum installation. This configuration is especially useful where the ceiling grid retains the reusable gel channel and filter weight assists the sealing engagement.

주요 기능

A continuous extruded knife edge presents one uninterrupted blade around the complete frame perimeter.

The blade engages the reusable gel channel built into compatible ceiling grids or equipment.

Filter weight and optional retainers maintain consistent penetration without crushing a foam gasket.

The sealing blade is physically separated from the potted mini-pleat pack to protect media integrity.

고객 제품 관심사

Knife-edge filters require precise blade geometry and careful alignment so the complete perimeter enters the receiving gel without damaging the trough.

A replacement filter does not align with the reusable ceiling-grid gel trough.A dimensionally controlled extruded blade follows the modular frame perimeter and enters the specified channel centerline.

Sharp or rough blade joints tear the gel surface during installation.Smooth mitered corners and deburred continuous edges allow clean penetration around the full frame.

A shallow blade disengages when the ceiling grid deflects.The blade projection is matched to the gel-trough depth with sufficient engagement allowance.

Installers press on the media face while seating the perimeter blade.A rigid aluminum frame and protective faceguard provide safe load-bearing handling points.
