Filtro de aire y filtración química
Filtro HEPA de bajo boro
A semiconductor-oriented HEPA panel using ePTFE or specially selected low-boron media and low-outgassing components to reduce airborne ionic contamination near sensitive processes.
- Low-Boron Media Selection
- Low-Outgassing Components
- Semiconductor Cleanroom Use
- Mini-Pleat Panel Design
Introducción del producto
The low-boron HEPA filter is designed for cleanroom zones where conventional borosilicate glass media may contribute trace ionic contaminants. A supported ePTFE membrane or qualified low-boron media is formed into a compact mini-pleat pack and bonded into an anodized-aluminium frame. Low-outgassing separators, polyurethane potting and gasket materials are selected to limit avoidable emissions from the assembled filter. The finished panel fits fan filter units, tool enclosures and recirculation modules serving lithography, wafer processing and other contamination-sensitive operations.
Características clave
Low-outgassing separators and potting compounds support use close to sensitive wafer and optics processes.
An anodized-aluminium frame provides a clean, non-shedding perimeter with stable seal geometry.
Mini-pleat construction supplies a broad active area within the shallow profile used by cleanroom terminals.
Preocupaciones del producto del cliente
Trace ionic and molecular emissions from filter materials can matter when the process operates at semiconductor contamination limits.
Conventional microglass media introduces an avoidable boron source near wafer processing.A supported ePTFE or selected low-boron pack removes the standard borosilicate media from the active filtration layer.
Adhesives and separators release volatile compounds into recirculated cleanroom air.Low-outgassing component choices reduce emissions from materials surrounding the filter pack.
Particles are released from unfinished frame surfaces during installation.Smooth anodized aluminium and sealed corners provide a cleanable, non-shedding perimeter.
A process-tool enclosure has limited space for a deep final filter.The shallow mini-pleat format fits common FFU and equipment-terminal depths.
