RO housing , also called membrane housing , is a crucial part of any RO water purification system , especially in industrial setups. Whether you’ re running a 500 LPH commercial plant or a 10 ,000 LPH industrial RO unit , the housing’ s durability , pressure handling capacity , and membrane compatibility directly affect water quality and system longevity.
RO housing is a pressure vessel that encloses the RO membrane. Industrial housings are built to handle high pressures— typically 300– 1200 PSI— and are made from materials like high strength plastic ( PP ) , stainless steel ( SS 304/316 ) , or FRP ( Fiber Reinforced Plastic ). Its main roles are to securely hold the membrane , allow safe water flow under high pressure , prevent leaks , and enable easy membrane replacement.
FRP Housing : Made of fiber reinforced plastic , handling 300– 600 PSI. Common sizes include 4040 and 8040 , suitable for light to medium industrial setups.
Stainless Steel Housing : Built with SS 304 or SS 316 , resistant to rust and corrosion , ideal for high pressure applications like pharmaceuticals or food processing.
Polypropylene ( PP ) Housing : Mostly used in domestic RO systems , lightweight and budget friendly , but limited for industrial applications.
Material plays a major role : SS 316 is more expensive than SS 304 , FRP is medium priced , and PP is the most affordable. Size also matters— larger housings like 8040 cost more due to material requirements. High pressure ratings , end cap and port designs , and premium brand certifications ( like BIS or NSF ) can further increase cost.
FRP 4040 : ₹1 ,200 – ₹1 ,800
FRP 8040 : ₹2 ,800 – ₹4 ,500
Stainless Steel 4040 : ₹4 ,500 – ₹6 ,000
Stainless Steel 8040 : ₹8 ,000 – ₹12 ,000
Polypropylene 4040 : ₹800 – ₹1 ,200
