    AI Overview
    Knife-edge HEPA filters are specialized, high-efficiency filters designed for cleanroom ceilings and Fan Filter Units (FFUs), featuring a protruding, tapered frame that seats into a gel-filled channel to provide an airtight, leak-proof seal. These lightweight, often anodized aluminum filters are critical for industries like pharmaceuticals, electronics, and hospitals. 
    Key Features and Benefits 
    • Airtight Sealing: The "knife-edge" sits securely in a gel seal track, eliminating leakage in ceiling grid systems.
    • High Efficiency: Often used for final filtration, they provide minimum efficiencies of 99.99% on 0.3

       particles (H13/H14).
    • Durable Construction: Built with anodized aluminum frames and protective powder-coated meshes to prevent media damage.
    • Optimal Airflow: Designed with microglass or PTFE media to ensure laminar flow in critical environments. 
    Typical Applications 
    • Cleanrooms: Used in terminal filtration for low-pressure drop, high-efficiency applications.
    • Hospitals/ICUs: Crucial for surgical rooms and isolation units to maintain sterilization.
    • Microelectronics/Pharmaceuticals: Prevent contamination during sensitive manufacturing processes. 
    Installation Considerations
    Installation involves placing the filter into a gel-seal terminal unit (like the HPLGS unit).

    • Handling: Always handle by the frame to avoid damaging the media.
    • Sealing: The gel-seal track must be facing up (towards the ceiling) to engage the knife-edge of the housing.
    • Security: Retaining clips are typically rotated 90 degrees to hold the filter securely in place.
