Independently developed by Vontron - the RO element ULP-1812-150 is a 12" x 1.8" Domestic Reverse Osmosis Membrane and is designed for low-salinity water resources such as tap water, well water, etc.

Working under extra low pressure, it can be used in water purifying devices and applications such as residences, hospitals or laboratories.

It will provide up to 150 US Gallons per day (GPD) / 23.7 Litres per hour (0.57 cubic meters) per day at optimum output.

Vontron ULP1812-150GPD TFC Membrane For Reverse Osmosis Systems

Reverse Osmosis membrane elements contain a preserving solution and should be flushed for 1 hour and the resultant permeate solution discarded before normal operation can be resumed. The elements must be kept moist at all times after initial wetting.

Elements should be immersed in a protective solution during storage, shipping or system shutdowns to prevent biological growth and frost damage.
