Industrial RO Membrane Element MAX-440-XLP
Ultra‑low operating pressure, as low as 100 PSI
Compared with conventional low‑pressure membranes (which typically require 150–200 PSI), the XLP lowers the minimum operating pressure down to 100 PSI (approximately 0.69 MPa), greatly reducing dependence on high‑pressure pumps. This means it can be directly matched with lower‑head pump units, significantly cutting both initial system investment and long‑term power consumption. It is especially suitable for applications with “pressure limitations” or where high‑pressure supply is not available.

Ultra‑low operating pressure, as low as 100 PSI – Compared with conventional low‑pressure membranes (which typically require 150–200 PSI), the XLP lowers the minimum operating pressure down to 100 PSI (approximately 0.69 MPa), greatly reducing dependence on high‑pressure pumps. This allows direct compatibility with lower‑head pump units, significantly cutting both initial system investment and long‑term power consumption. It is especially suitable for applications with pressure limitations or where high‑pressure supply is not available.
High water production even at low pressure – Under low‑pressure conditions, it still delivers an exceptionally large water production capacity of 14,000 GPD (gallons per day), meeting the continuous water demand of industrial processes and significantly improving overall water production efficiency.
Comprehensive energy saving and cost reduction – Low operating pressure, reduced pump power, lower cleaning frequency, and extended membrane replacement intervals lead to a substantial overall reduction in operation and maintenance costs.
