4040 Vontron Membrane

The Vontron 4040 RO membrane is a high-performance reverse osmosis element designed for light industrial and commercial water purification applications. It features a 4-inch diameter and 40-inch length, suitable for standard 4040 pressure vessels. This thin-film composite (TFC) membrane offers excellent salt rejection (typically >98%) and consistent output, making it ideal for treating tap water, brackish water, or low-salinity feedwater. It provides a nominal flow rate of 2,500 GPD (gallons per day) under standard test conditions.
