AMI 2.5” End Port FRP

Applied Membranes Inc Water Treatment Components
1200 PSI End Port Seawater Membrane Housing Pressure Vessels

AMI fiberglass membrane housings are rated at 1,200 psi and specially designed for seawater reverse osmosis membranes used in marine applications.  Commonly used in watermakers, AMI FRP seawater pressure vessels are suitable for seawater desalination in shipboard applications, watermakers, land-based desalinators and sea-based desalinators.

AMI FRP seawater RO membrane housing end caps are designed for direct connection to Industry Standard Style 2.5" diameter male style elements (such as Applied Membranes, Inc. AMI Membranes, and FilmTec style membranes).

Benefits of AMI Seawater RO Membrane Housings

  • Strong coated FRP/fiberglass for extended life under corrosive conditions
  • Suitable for seawater conditions
  • Direct connect to industry-standard 2.5" diameter seawater membrane elements
  • Designed for ease of installation and maintenance
  • Ideal for operating pressures up to 1,200 PSI
  • AMI Products have earned an industry-wide reputation for their high quality and superior performance
  • Large inventory available for immediate shipment

Quality Control Inspected ISO 9001:2015 Certified   In Stock for Immediate Shipment
