Membrane Housing, 3" x 12"

This Pureteck membrane housing measures 3 inches in diameter by 12 inches long and is built to hold a reverse osmosis membrane element of matching size. The pressure vessel encloses the membrane and directs feed water across its surface, separating purified permeate from concentrated reject water in commercial and light-industrial reverse osmosis applications. It is the structural heart of an RO stage, providing the sealed, pressure-rated enclosure that makes membrane filtration possible.

A Durable Pressure Vessel

Membrane housings must withstand the operating pressures required to push water through a semipermeable RO membrane, all while keeping the feed, permeate, and concentrate streams properly isolated from one another. Any leakage between streams would compromise water quality, so a well-built housing is essential to system performance. The 3 x 12-inch format suits compact higher-output systems that need more membrane area than a standard residential under-sink unit provides, bridging the gap between small point-of-use systems and large industrial trains.

• 3-inch by 12-inch RO membrane housing
• Houses a matching reverse osmosis membrane element
• Withstands the operating pressures of RO systems
• Keeps permeate and concentrate streams isolated
• Suited to compact commercial and light-industrial RO
• Provides a rugged, pressure-rated enclosure

Whether you are building a new reverse osmosis system or replacing a worn or cracked vessel in an existing one, this Pureteck housing provides the rugged enclosure your membrane needs to operate safely and efficiently. Pairing it with the correct 3 x 12 membrane element ensures reliable purification and steady permeate output across the life of the system. As a housing rather than a consumable, it is a long-term investment that supports many membrane changes over its service life, making it a practical foundation for compact higher-capacity RO installations in small businesses, light manufacturing, and demanding point-of-entry settings. As a long-lived housing rather than a consumable, it supports many membrane changes over its service life, making it a practical foundation for compact higher-capacity RO installations in small businesses and demanding point-of-entry settings. For builders assembling compact higher-output RO systems, this Pureteck housing is the rugged, reusable backbone that lets the membrane do its work under pressure for years.
