The First Line 4040, 300 PSI FRP Membrane Housing is engineered for dependable performance in commercial and light industrial reverse osmosis systems. Constructed from fiberglass reinforced plastic (FRP), this housing offers excellent resistance to corrosion, chemicals, and pressure fatigue while maintaining a lightweight profile for easier installation.

 

Designed to accommodate one standard 4040 RO membrane, the end-port configuration supports efficient flow distribution and simplified system layout. Precision-molded internal components ensure proper membrane alignment and secure sealing under continuous operation.

 

This membrane housing is ideal for applications including commercial water purification, food and beverage processing, spot-free rinse systems, and process water treatment. Built to meet professional system integrator and OEM standards, the First Line 4040 housing delivers consistent performance, durability, and long-term reliability.
