Vontron LP21-4040 | Low Pressure RO Membrane (2400 GPD / 4x40-inch)

The Vontron LP21-4040 is a commercial-grade, low-pressure Reverse Osmosis (RO) membrane designed for brackish water treatment. Featuring a 4x40-inch standard configuration, it delivers a permeate flow of 2,400 Gallons Per Day (GPD) with a high stabilized salt rejection rate of 99.5%. It is specifically engineered to operate at a lower testing pressure (225 psi), reducing overall pump energy costs.

Optimize your commercial water purification plant with the Vontron LP21-4040 Low Pressure RO Membrane. In Pakistan, dealing with highly brackish ground water (especially in cities like Karachi and Faisalabad) requires robust filtration. However, running high-pressure pumps constantly drives up electricity bills. The LP (Low Pressure) series by Vontron solves this by delivering exceptionally high flow rates at significantly lower operating pressures.

This 4x40-inch Polyamide Thin-Film Composite membrane is the industry standard for commercial drinking water plants, hospital dialysis setups, and mid-sized industrial boilers. It easily handles feed water with a TDS of up to 10,000 ppm, stripping away 99.5% of dissolved salts, heavy metals, and silica. By requiring only 225 psi to achieve its 2,400 GPD output, it extends the lifespan of your high-pressure pumps and reduces energy consumption drastically.

• 2,400 GPD Output: Generates up to 9.1 cubic meters of highly purified water per day per element.
• 99.5% Salt Rejection: Provides excellent desalination, easily converting heavy brackish well water into WHO-standard drinking water.
• Universal 4040 Fit: The 4x40-inch dimension drops perfectly into standard stainless steel or FRP membrane housings.

Frequently Asked Questions (FAQs):

Q: What is the price of the Vontron LP21-4040 in Pakistan?

A: Visit Kamadi.pk for current pricing. We supply authentic, vacuum-sealed Vontron membranes directly to commercial water plants nationwide.

Q: Can this replace a FilmTec BW30-4040?

A: Yes. The LP21-4040 is a direct dimensional and functional equivalent to standard 4040 brackish water membranes, making it a highly cost-effective drop-in replacement.

Q: Does it work for seawater?

A: No. This is a Brackish Water (BW) membrane designed for tap or well water. For ocean water, you need a Seawater (SW) membrane like the SW8040 series.
