Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Filtration And Membranes. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The 1812-75 is a tubular reverse osmosis membrane intended as a purification component for domestic water purifiers and RO machines. Its nominal dimensions are 1.8 × 12 inches, with a specified flow rate of 75 gallons per day.
The listed operating pressure is 60–80 PSI, and the model table specifies salt rejection of at least 97%. The membrane material is identified as polyamide. The product is described for household, ho are listed as available. Finished products are stated to receive 100% inspection.
Published production capacity is 500,000 pieces per year. For procurement planning, buyers should confirm the required feed-water conditions, test method used to determine flow and salt rejection, expected performance under the actual installation conditions, and dimensional tolerances.
Compatibility with the intended membrane housing and RO system should also be verified before ordering. Ask for documented limits covering feed-water temperature, pH, chlorine exposure, recovery rate, and maximum pressure because these parameters are not provided in the available specifications.
Packaging information appears in two configurations: the model table lists 30 pieces per carton with a 30 × 30 × 35 cm carton, while the basic specification lists 50 pieces per carton and a 49.5 × 29.5 × 31.5 carton specification.
Buyers should obtain written confirmation of the applicable packing quantity, carton dimensions, individual package dimensions, gross weight basis, labeling, and inspection criteria for their order.
A one-year warranty is stated for the product and core components, but its coverage, exclusions, claim procedure, and starting date should be confirmed in the purchase agreement.
