PermSelect® membrane gas exchangers from 2500 cm2 and larger, provide a highly efficient radial flow design through a densely packed bundle of uniformly spaced apart hollow fibers. Our membranes are commercially available with surface areas of 10, 100, 1,000, 2,500,  7,500 cm2, and 1.0 and 2.1 meters square. Contact us to discuss your specific requirements. 

Product Comparison Table


PermSelect® membrane gas exchangers, also known as membrane modules, use silicone hollow fibers with exceptional gas transfer properties. Because silicone is dense (non-porous), liquids cannot transfer through the membrane. This enables silicone's use in liquid contacting applications with all compatible liquids regardless of liquid surface tension. Moreover, the dense membrane also enables separating gases from mixtures due to the permeability difference between gases in silicone. Our versatile gas exchangers have been used to control gas levels in liquids including for degassing liquids in pharmaceutical industry, media gassing in cell culture bioreactors, degassing inks, and degassing water.  Our membranes are also ideal for humidifying gas streams (such as for fuel cells); to separate VOCs and solvents from water and air, and to remove moisture from gas streams.
