GROSITE REVERSE OSMOSIS
Affordable R.O. Systems
The GROSITE Economy Reverse Osmosis system features a DOW Filmtec TFC membrane rated at 99 percent rejection - the highest rejection rating in the industry. This means that this system will remove an average of 99 percent of all impurities from the water source. The in-line sediment and carbon pre-filters provide effective filtration without sacrificing water quality. The Economy Reverse Osmosis systems feature brass garden hose bib connection for easy connection to a water supply. An external flow restrictor provides for easy maintenance and or customizing the rejection rate. John Guest Quick Connect fittings throughout allow for easy cartridge replacement.
The Economy Reverse Osmosis systems are not designed to be used in an on demand application. These units do not have an automatic shut-off valve as they are not designed for use with a float switch or in a permanently installed application. These are portable units designed to be installed and removed from the water source when used.
The GROSITE Standard Reverse Osmosis system features a DOW Filmtec TFC membrane rated at 99 percent rejection - the highest rejection rating in the industry. This means that this system will remove an average of 99 percent of all impurities from the water source. The standard 10 inch sediment and carbon pre-filters provide effective filtration while maintaining compatibility with any standard 2.5 inch diameter by 10 inch long filter cartridge. The Standard Reverse Osmosis systems feature a brass self-tapping feed valve and a clamp-on drain connections for easy permanent or semi-permanent installation to a copper pipe water supply. An external flow restrictor provides for easy maintenance and or customizing the rejection rate. John Guest Quick Connect fittings throughout allow for easy serviceability.
The Standard Reverse Osmosis systems are designed to be used in an on demand application. These units have an automatic shut-off valve as they are designed for use with a float switch or valve in a permanently installed application. The automatic shut-off valve will shut-off the incoming water when the output is stopped via a float valve or manual valve. This allows the unit to stop the flow of incoming water when there is no demand for output water - saving water for the end user. These are not portable units designed to be installed and removed from the water source when used.
