Bekaert OI8040Xf

Summary

Product Identification

The BEKAERT Model OI8040Xf Pressure Vessel is designed for continuous use as housing for membrane filtration elements to purify typical brackish waters. It accommodates any make of eight-inch nominal diameter spiral-wound elements, as well as many hollow fiber elements. Element interface hardware for the specified element is supplied with the vessel.

The Model OI8040Xf is an end-ported vessel and can house from one (OI80401f) to eight (OI80408f) 40-inch standard length, 8-inch standard diameter membranes.

The vessel has been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. ASME Code stamped vessels are available at an additional cost.
