FRP Filter Housings

FRP Filter Housings are corrosion-resistant vessels that hold cartridge or bag filters for water and effluent polishing. Constructed of fiberglass-resin composite, they are “particularly suitable for applications requiring corrosion resistance and high-pressure environments”. These housings accommodate standard filter elements (5″, 10″, 20″ cartridges or #1/#2 filter bags) in single or multi-element configurations. Internal supports and drain/vent ports allow easy media replacement. By effectively removing suspended solids and debris, FRP filter housings protect downstream equipment and extend filter life.

Key Features

  • Corrosion-Resistant Body: Entire housing is FRP (galvanized or steel fasteners are optional), ensuring no rust contact with fluids.
  • High Pressure Rating: Designed for typical working pressures (e.g. 150–300 psi), thanks to thick-walled fiberglass laminates.
  • Leak-Proof Seals: Heavy-duty clamp or bolted lids with o-ring seals prevent bypass. Optional double O-rings or pneumatic clamps available.
  • Versatile Configurations: Available as single- or multi-housing racks, horizontal or vertical orientation. Customizable port sizes and vent/drain valves.

Benefits

  • Excellent Chemical Compatibility: Suitable for acids, alkalis, solvents – ideal in chemical, pharmaceutical, and microelectronics rinse systems.
  • Lightweight and Durable: Easier to handle than steel housings, yet rugged under pressure.
  • Cost-Effective Maintenance: FRP won’t pit or perforate like metal, so housings last for years without recoating.

Applications

Water treatment (RO pretreatment, desalination), industrial process filtration, effluent polishing, brine filtration, and any system where corrosion of metal housings is a concern. Also common in food & beverage and pharmaceutical (FDA-approved options).


Technical Specifications

Typically available in 10″, 20″, 40″ heights; multi-cartridge banks (5–20 cartridges). Standard 2″–4″ flanged inlets/outlets. FRP resin often vinyl ester or high-build polyesters. Pressure vessels follow ASME Section X or recognized pressure vessel codes.


Unique Selling Points

As Snowate notes, FRP filter housings are a “flexible” and “easy to maintain” solution. We stock UL-listed NSF-61 FRP housings and can custom-manufacture special sizes. Our design ensures “high pressure tolerance” and zero leakage even under rigorous service.
