PROTEC™ Membrane Housing Pressure Vessels
4" Side Port Fiberglass Membrane Housing Pressure Vessels

Description
PROTEC pressure vessels are constructed of corrosion resistant filament wound fiberglass reinforced epoxy tubing and are designed for continuous use as housing for membrane filtration elements to purify typical brackish waters.

This style of fiberglass membrane housing is designed for direct connection to AMI and FilmTec/DOW male style elements and is supplied with the element interface hardware for this style.

Side ported vessels with feed and concentrate connections located in the side wall of the vessel shell. 4" Diameter Side Port Pressure Vessels are available to house from one to six 40" elements. Available operating pressures are 300 and 450 PSI.

PROTEC Vessels have been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. At an additional cost, vessels can be inspected during fabrication by an ASME Authorized Inspector and Code stamped.

Materials
Shell: Filament Would, Epoxy FRP
End Plugs/Sealing Plates: PVC Thermoplastic
Retaining Rings: Stainless Steel

Hardware Components
Pressure vessels include shell, end enclosure hardware and seals. Mounting straps and components are sold separately.

Note: AMI Brand 4" FRP Membrane Housings have been discontinued.
