AMI Stainless Steel Pressure Vessel Membrane Housings for RO Systems

Stainless Steel Membrane Housing Pressure Vessels enhance system appearance and allow you to take full advantage of the membrane capability. Safer and more reliable than PVC membrane pressure vessels. This style is designed for direct connection to AMI/Applied Membranes and FilmTec/DOW style elements. The AMI 4” Stainless Steel pressure vessels are ideal for pressures up to 300 PSI.
