Introducción del producto

This version forms the knife edge directly into the anodized aluminum filter frame, pairing it with supported hydrophobic ePTFE media. The rigid blade enters gel retained by an open-plenum ceiling grid, so the replaceable panel carries no gasket or filled trough. Its low-outgassing membrane construction suits microelectronic and other sensitive mini-environments where both seal geometry and material emissions matter.

Características clave

Filter-side sealing blade

The continuous aluminum edge gives a defined interface with gel retained in the ceiling support grid.

Sensitive-process material choice

Low-outgassing membrane and frame materials help reduce avoidable molecular contribution near critical equipment.

No filter-mounted gel

Gel remains in the grid, simplifying the replaceable element while shifting inspection to the ceiling receiver.

Applications

Appropriate for common-plenum semiconductor cleanrooms, mini-environment ceilings and sensitive production zones using gel-filled grid receivers. The blade location, gel depth and frame tolerance must be coordinated before purchase because this filter cannot seal against a flat gasket land.

Solutions for Your Application

Organic emissions from final-filter components can affect a sensitive microelectronic process.The low-outgassing ePTFE construction limits avoidable material contribution while maintaining H14 particulate filtration.

The knife edge lands beside rather than inside the ceiling gel channel.Verify the blade offset against the actual grid section and trial-fit a dimensioned sample before batch supply.

Opciones disponibles

Define blade offset, frame depth, face dimensions, grille arrangement and low-outgassing material requirements for the grid.
