Product Specification

Lanlang 4040 SS pressure vessels for housing 4040 membrane elements offer high operating pressure which allow you to take full advantage of the membrane capability. Stainless steel membrane pressure vessels are considered safer and more reliable than PVC membrane pressure vessels.
Designed for direct connection to industry-standard 4x40 membrane elements with 3/4" male product water tubes (stinger style). The End-Clamp style end closures are designed for ease of installing and replacing membrane elements, with standard ½" FNPT threaded connections: no special fittings required. Each membrane housing is individually inspected for quality assurance.
