FRP membrane pressure vessels are produced from spools of fiberglass fiber and held together by a specific grade of epoxy resin that is cured at elevated temperatures. The manufacturing process is computer controlled with each strand of glass fiber placed at a specific location and orientation to achieve optimum strength. The glass fiber and resin mixture is wound around a precision-machined mandrill, which accounts for the perfectly circular, defect free interior of today’s RO vessels. The vessels are often painted white to reduce light transmission through the vessel to minimize growth of algae and other biological concerns.

8” RO membrane pressure vessels / membrane housings are specially made from high grade composite material for ensuring longer service life and durability. Our membrane pressure vessels are available at very affordable with market selling rates. We provide a wide range of 8″ and 4″ RO housings, manufactured by leading brands in membrane and FRP Pressure vessels in the world.
