Membrane Solutions for a Safer, Cleaner, More Productive World

Air Products Membrane Solutions specializes in the development of hollow fiber membrane separators and systems for onsite gas generation. We commercialized gas membrane separation in the 1970s. Today, we design, engineer, manufacture, and market a full portfolio of PRISM® Membrane Separators, Marine Systems, and Engineered-to-Order Systems. We protect lives and goods at sea, on land, and in the air; create more sustainable energy sources; and raise productivity across a variety of industries and applications.

PRISM Membrane separators are available through two channels:

Original Equipment Manufacturing (OEM) Arrangements

This global network of value-added resellers integrate the PRISM Membrane gas separators into systems for a variety of applications, from food preservation to scuba-diving air. 

Air Products Engineered Systems Group

These fully-assembled membrane systems are fabricated to the highest engineering classifications, and are the same nitrogen-membrane systems that we use in our own facilities.

Frequently Asked Questions

Will PRISM membranes be damaged by liquid water and oil?

PRISM membranes will not be permanently damaged by liquid water. The membrane performance can be restored by flowing warm, dry air through the membrane until all the liquid water is removed. The membranes will not be affected by oil vapor in the feed stream; however, the membranes will be permanently damaged by liquid oil entering or condensing in the membrane.
