FFU Gel Seal (Tradução)

A refillable fluid-gel trough that forms a conformable low-bypass seal around an FFU HEPA filter knife-edge interface.

Introdução do produto

The FFU gel seal uses a continuous channel of stable silicone gel to receive the projecting knife edge of a mating HEPA filter or housing. As the knife edge enters the gel, the fluid conforms around minor dimensional variation without the compression load required by a foam gasket. An aluminum trough retains the gel around the full perimeter, with sealed corners and an optional fill port for controlled service. Trough dimensions, gel depth, viscosity and knife-edge immersion must match the installed filter system.

Características-chave

Continuous fluid gel conforms around the mating knife edge along all four sides.

A rigid aluminum trough controls gel depth and prevents migration from the sealing path.

Mitered or welded corner construction maintains channel continuity at perimeter turns.

A capped fill port supports controlled topping-up or replacement of compatible gel.

Preocupações do produto do cliente

A fluid seal only performs reliably when the trough remains continuous and the mating knife edge reaches the correct gel depth.

Insufficient gel depth leaves sections of the knife edge unsealed.Trough volume and fill level are matched to the knife-edge height and intended immersion.

Corner discontinuities become bypass paths around an otherwise sealed perimeter.Sealed corner joints maintain one uninterrupted gel channel around the frame.

Incompatible gel hardens, flows or contaminates the mating surface.Gel chemistry and consistency are selected for the operating temperature and filter interface materials.

Overfilling causes gel displacement during filter installation.A defined trough profile and controlled refill quantity keep the gel below its retention lips.
