Product Introduction

The gel-seal ePTFE model places a continuous fluid channel in the anodized aluminum perimeter. A housing knife edge enters the gel when the panel is raised into a bottom-load terminal, while the supported membrane provides H14 efficiency, low outgassing and high tensile strength. This arrangement is distinct from the gasket model because sealing depends on knife-edge immersion rather than clamp compression.

Key Features

Low-bypass fluid path

The continuous gel channel conforms around the mating knife edge and can reveal discontinuities through its impression.

Maintenance-tolerant media

Supported ePTFE reduces the risk of incidental handling damage during room-side replacement.

Aseptic service geometry

The bottom-load format allows filter changeout without opening a common plenum above the room.

Applications

Selected for aseptic pharmaceutical terminals, biotechnology rooms and controlled filling areas with a housing knife edge and room-side access. It is useful when a fluid seal and durable membrane media are both required, provided gel chemistry is compatible with the sanitation program.

Solutions for Your Application

Filter replacement above an aseptic room would disturb inaccessible plenum services.The gel-channel panel supports bottom-load changeout from the controlled room when paired with a compatible terminal.

Old gel residue prevents complete knife-edge immersion.Remove approved residue from the housing edge, inspect the new channel and insert the filter vertically without dragging.

Available Options

Choose gel material, channel dimensions, exact frame size, upstream screen and room-side retaining hardware for the terminal.
