Membrane Housings - Reverse Osmosis

A membrane housing for reverse osmosis measures 2.5 and 4 inches in diameter and either 14, 21, 40, 80, or 120 inches in length. These standard dimensions make membrane housings and other components easily interchangeable. Membrane housings come in a variety of materials, such as PVC, stainless steel, and fiberglass.

Residential Membrane Housings

These membrane housings are for residential, point of use, or under sink reverse osmosis systems. All membrane housings are manufactured using high-quality polypropylene, and accept all 12" standard sizes. We also offer a wide variety of RO Membranes for these systems.

Commercial PVC Membrane Housings

The Axeon (Champ-style) PVC membrane housings have been the global standard for commercial reverse osmosis pressure vessels for over a decade. The addition of two side ports provides a total of four open ports that can be custom configured to meet wide variety specialized applications. The patented snap ring end plug design allows for more efficient installation and maintenance.

Commercial Stainless Steel Membrane Housings

Stainless steel membrane housings are safe to use with purification technologies such as ultraviolet disinfection systems. They also do not warp or weep like fiberglass membrane housings. Stainless steel membrane housings are able to withstand temperatures up to 200º F in addition to a much wider water pH range during cleaning. Stainless steel is generally preferred where sanitation is critical (like hospitals).

Fiberglass Membrane Housings

ROPV 2.5" x 21" and 4" x 40" fiberglass membrane housings are manufactured with only high-quality materials.  These fiberglass pressure vessels accommodate standard 2.5" or 4” membrane filtration elements and operate at pressures up to 1000 psi.  Fiberglass housings are stronger than PVC and less corrosive than stainless steel.
