Water equipment factories producing hotel water dispensers and small bottled machines need cost-effective RO membrane with balanced flux and desalination efficiency. Too low water yield limits equipment market competitiveness, while ultra-high salt rejection models push up raw material costs. Our LF-ULP medium-pressure commercial RO element perfectly balances output and performance, operating under 150psi pressure with stable 99.0–99.6 salt rejection range, multiple flux specifications matching 1–10 ton small pure water machinery. Lightweight spiral winding structure simplifies after-sales manual replacement work, and mild anti-scaling TFC coating cuts scale inhibitor dosage for tap water raw water.
All LF-ULP commercial RO membrane and mini PAN internal pressure UF membrane modules are contained within our water filter element.
