Household RO reverse osmosis membrane shell 1812 quick connect pure water machine accessories 50G-100G universal

Description :

  RO membrane shell is the core pressure bearing component in household and commercial reverse osmosis water purification systems, mainly used to fix and protect RO reverse osmosis membrane elements, ensuring effective separation of impurities in raw water under high pressure environment. This product is designed specifically for household direct drinking water dispensers, ultrafiltration and reverse osmosis pure water machines, solving the problems of complex installation and easy leakage of traditional membrane shells. Through a quick connect design, the filter element can be quickly replaced without the need for tools, suitable for 1812 standard RO membranes. Its core function is to provide a stable working pressure environment for water purification systems with a flux of 50G to 100G, ensuring that the effluent quality meets direct drinking standards, and is a key component in maintaining household drinking water safety.

  The RO membrane shell is made of food grade ABS or high-strength composite materials, which have excellent pressure resistance and corrosion resistance, and comply with water related hygiene and safety standards. The product specifications strictly match the 1812 model membrane element, and the interface type is standard Quick Connect, compatible with 2 or 3 PE pipes. The working pressure range is usually between 0.1-0.6 MPa, and the burst pressure is much higher than the daily use limit, ensuring long-term operation without rupture or leakage. The surface of the shell is smooth, and the inner wall is precision machined to reduce wear on the RO membrane surface. Adhere to the industry standard NSF/ANSI related component specifications to ensure that the material is non-toxic and odorless, does not affect the taste of the effluent, and is suitable for replacement and maintenance of various brands of pure water machines.

  When selecting, it is important to confirm whether the membrane element specifications of the original water purifier are 1812 series, and whether the flux requirement is 50G or 100G. Although the two have similar appearances, there may be slight differences in the internal support structure to accommodate membranes of different lengths. This product is suitable for most assembled household water purifiers, desktop water purifiers, and some small commercial equipment. Not suitable for industrial large 4040 or 8040 specification membrane components, and not compatible with old-fashioned threaded interface non quick connect systems. If your device is using an integrated filter cartridge machine, please disassemble it first to confirm if there is an independent membrane housing structure. For households pursuing high flow water usage, it is recommended to confirm whether the pump pressure matches the starting pressure of the 100G membrane to avoid frequent start stop affecting its lifespan.

  When installing the RO membrane housing, it is necessary to check whether the O-ring is intact and apply a small amount of silicone grease for lubrication to prevent seal failure and water leakage caused by dry friction. The direction of the water inlet and the wastewater outlet must be strictly connected according to the machine identification. Reverse connection may result in inability to produce water or damage to the membrane components. In daily maintenance, it is recommended to check the fastening of the two end covers of the membrane housing every 6-12 months. If cracks or severe scratches are found, they should be replaced in a timely manner. If there is an increase in TDS value in the effluent, it is necessary to first check whether the RO membrane has failed, and then check whether there are cracks inside the membrane shell that cause a short circuit in the raw water. When not in use for a long time, the accumulated water in the empty shell should be drained to avoid bacterial growth or winter freezing. Regular flushing can extend the service life of the entire water purification system.
