VONTRON OSMOSIS MEMBRANE 50 GALLONS PER DAY
This membrane is a direct replacement for membranes fitted to all Vyair Reverse Osmosis Water Filters.
This membrane is a suitable replacement for most 50gallons per day reverse osmosis water filters.
VONTRON BRAND FROM VONTRON TECHNOLOGY CO LIMITED
COMPLIES FULLY WITH
ANSI/NSF Standard 58-1997
Don't be confused by the quality, these are top quality membranes and ar TFC film. We have tested them the last one I fitted input water TDS 240 output water TDS 7
Why are they so sensibly priced? We are the direct importers, dealing with the manufacturer buying huge quantities. NO MIDDLE MEN.
BRAND NEW IN PROTECTIVE PACKAGING
FITS MOST STANDARD MEMBRANE HOUSINGS
FITS MOST REVERSE OSMOSIS SYSTEMS
The 1812-sized residential membrane elements are mainly applicable to various small-sized systems, such as household reverse osmosis water purifier and other water purifying devices in hospital and laboratory.
Being suitable for the desalting treatment of those water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, etc., ULP series are mainly applicable to numerous applications of various sizes, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.

Keep elements moist at all times after initial wetting
Permeate water obtained from first hour of operation should
be discarded in order to flush the protective solution in the
elements.
Vontron elements should be immersed in a protective solution
during storage, shipping or system shutdowns to prevent
biological growth and frost damage. The standard storage
solution contains one (1) weight percent sodium bisulfite or
sodium metabisulfite (food grade). For short term storage of one week, one (1) weight percent sodium metabisulfite
solution is adequate for inhibiting biological growth.
