Detailed Description (4 Options):4040 Commercial RO Membranes / Stainless Steel 4040 Membrane Housing BW-4040HF 2400 GPD Commercial RO MembraneReverse Osmosis membrane elements for commercial drinking water systems are the industry’s most reliable method of water filtration. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. Our Reverse Osmosis membranes are shipped dry for convenient handling and long shelf-life. Our membranes are rated at 60 psi and will purify about 20% more water than competitive elements rated at 60 psi. BW-4040 standard flow is 2400 GPD @ 100 PSI ,Now if you the reduce pressure to 60 PSI,pressure reduced 40% ,therefore permeate flow will be approximately 1440 GPDWe suggest changing your membrane every 2 years XLP-4040 2300 GPD Commercial RO Membrane same XLE model. Both are the sameReverse Osmosis membrane elements for commercial drinking water systems are the industry’s most reliable method of water filtration.

Continuous exposure, however, may damage the membrane and should be avoided. If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void. 4040 Reverse Osmosis Membranes for many Applications such as:Car Washes Whole House Reverse Osmosis Commercial Reverse Osmosis Agricultural Industrial
