STJH-LOW-RESISTANCE-HEPA-H14-KNIFE610

Low-Resistance HEPA Filter 610 mm Knife-Edge ePTFE

A low-resistance H14 membrane panel with an integral knife edge for common-plenum gel-grid ceilings.

Integral frame knife edge
Full-module H14 ePTFE
Common-plenum installation

Introduction de produit

The knife-edge version places the rigid sealing blade on the approximately 610 mm filter frame, allowing it to enter gel held in the ceiling grid. Supported hydrophobic ePTFE media supplies H14 performance with lower average resistance and better handling strength than traditional fragile media. This configuration is chosen for open common plenums, not housings that expect gel on the filter itself.

Key Features

Grid-held gel compatibility

The aluminum knife edge seats into a gel trough built into the ceiling support system.

Energy-conscious media pack

Low-resistance membrane construction helps limit recirculation-fan demand across large ceiling fields.

Clean installation profile

The rigid edge provides a defined insertion geometry without compressing a dry gasket.

Applications

Specified for common-plenum life-science ceilings, mini-environment grids and large laminar-flow fields that retain gel in the support grid. It helps facilities combine an H14 membrane pack with low resistance while keeping the fluid seal outside the replaceable filter.

Solutions for Your Application

The gel-grid ceiling receives a filter with a flat gasket frame.Use the integral knife-edge model and match its blade centerline to the existing gel trough.

A full ceiling field develops high fan demand as final filters load.The ePTFE media is selected for a lower average resistance profile; track actual pressure drop for change planning.

Options disponibles

Specify exact knife-edge offset, face dimensions, media-pack depth, airflow direction and protective screen for the common-plenum grid.
