Filtro HEPA FFU
A compact mini-pleat final filter that restores high-efficiency particle filtration in an existing cleanroom fan filter unit.
- Dense Mini-Pleat Media
- Low-Profile FFU Frame
- Sealed Perimeter Pack
- Matched Gasket Interface
Introdução do produto
The FFU HEPA filter is the final air-cleaning element installed beneath the fan section of a fan filter unit. Fine glass-fiber media is formed into closely spaced mini-pleats and stabilized with hot-melt separators to provide a large filtration area within a shallow frame. Perimeter potting prevents bypass between the media pack and aluminum frame, while a compression gasket seals the filter against its supporting surface. Replacement size, efficiency class, pressure drop, gasket side and airflow direction must match the original FFU design.
Características-chave
Continuous perimeter potting closes the leakage path between media and frame.
A fitted compression gasket seals the filter to the FFU housing or ceiling interface.
Protective face grids reduce accidental pleat damage during handling and installation.
Preocupações do produto do cliente
A replacement HEPA panel must fit the FFU precisely while preserving airflow and eliminating bypass around the media pack.
A frame with incorrect dimensions leaves gaps or cannot enter the FFU housing.Face size, depth and corner tolerances are matched to the original filter envelope.
An unsuitable pressure drop reduces delivered cleanroom airflow.Media area and pleat geometry are selected for the FFU operating face velocity.
Air bypasses the media through an incompatible gasket arrangement.Gasket material, width, thickness and upstream or downstream position are matched to the sealing surface.
Pleats are damaged during overhead handling and replacement.Optional upstream and downstream protective grids shield the media without blocking its open area.
