Water machinery OEM factories producing commercial water dispensers and small bottled water equipment are facing the dilemma of balancing product competitiveness and raw material cost. Ultra-high salt rejection customized Reverse Osmosis membrane element pushes up manufacturing cost, while low-flux cheap Reverse Osmosis membrane reduces machine market attractiveness. LF-ULP medium-pressure Reverse Osmosis membrane filter perfectly balances water yield and desalination efficiency, operating under 150psi medium pressure with salt rejection range 99.0%–99.6, multiple flux specifications matching 1–10 ton small pure water machinery. This economical RO membrane is matched with compact PAN Ultrafiltration membrane module to block pipeline rust and tiny debris, avoiding scratch damage on each RO membrane element’s TFC separation layer. All LF-ULP commercial RO membrane filter and mini-size UF membrane are categorized inside our water filter element.

Commercial Equipment Matching Scenarios
1. 1–5 ton small bottled mineral water production equipment
2. Hotel, office and school centralized commercial drinking water dispenser
3. Dairy factory fruit juice small blending purification unit
4. Clinic and laboratory mini sterile water preparation machine
5. Rural household central drinking water purification equipment
6. Small catering factory food cleaning pure water system
OEM Friendly Core Advantages Of LF-ULP RO Membrane Element
1. Balanced water yield and desalination rate without excessive raw material procurement cost of Reverse Osmosis membrane
2. Universal 4040 overall dimension fits all small FRP pressure vessels for Reverse Osmosis membrane element
3. Mild anti-scaling TFC coating cuts daily scale inhibitor dosage for this commercial RO membrane filter
4. Light weight structure supports convenient on-site manual replacement of each single RO membrane
5. Wide pH cleaning range supports simple daily maintenance of RO membrane filter
6. Compact PAN Ultrafiltration membrane module saves equipment cabinet internal space together with Reverse Osmosis membrane
