Water filters are suitable for the family, hotel and restaurant use. You can choose proper filter cartridge according to local water quality. Proper filter cartridge can remove odor, smell, color and even organic chemicals from tap water. These water filters can use almost all 10" standard filter cartridges available on current market. The water filter comes with a quick-easy diverter valve to install the filter without extra fittings.

UF Systems

UF Water Purifiers, Ultra Filter Water Systems.

Water ultrafiltration (UF) is a filtration process that uses standard home water pressure to push water through its semi-permeable membrane. Ultrafiltration (UF) removes viruses, bacteria, as well as suspended particles from your drinking water. Particles and materials of high molecular weight are unable to pass through the 0.01 micron UF membrane so that only fresh water and dissolved minerals get through.

Softeners

Softeners

Economy Manual/Automatic Softeners, Fully Automatic Comfort Softeners, Wall-mounted Bath Water Softeners, Central Water Purifiers, Cabinet Water Softeners.

Compact systems to remove hardness and prevent formation of scale deposits. Feedwater enters the unit and passes through the ion exchange resin, which causes the replacement of calcium and magnesium ions with sodium ions to give softened water. Periodically, the exchanged calcium and magnesium is removed from the resin by regeneration using salt solution supplied from the brine tank. The regeneration process is fully automatic.

RO Tanks

RO Tanks

Pressure Tanks for Reverse Osmosis Systems.

Pressurized tanks are used as a water reservoir for RO systems. Water is filtered through a reverse osmosis membrane very slowly and people don't have the patience to wait a long time to get a glass of water. For this reason the residential RO units need a water storage tank to store the purified water. The RO tanks can deliver stable and constant water flow when the faucet is opened.

RO Systems

Domestic Reverse Osmosis Systems, Commercial Reverse Osmosis Systems.

RO water systems, also known as Reverse osmosis water systems, provide refreshing and clean water to homes, offices, and many other locations. RO water systems are known for reducing contaminants, such as lead, arsenic, copper, nitrates, and more.

RO Faucets & Valves

The RO unit uses its own faucet, which is usually installed on the kitchen sink. Adapter Valves are installed by disconnecting the faucet line from the supply line and connecting each to either end of the adapter valve. Includes a ball valve to shut off the RO feed water at the source. Diverter valves attach to a standard threaded faucet. The handle on the valve allows you to switch the water flow back and forth from the sink to the filter without disconnecting the valve.

Push-in Connectors

Push-in Connectors

Push-in Fittings and Valves, Tubes and Accessories for Push-in Connectors.

One of the benefits of push-in fittings is that installations can be quickly disconnected for service. The tube can be removed by simply pushing the collet in squarely against the fitting. With the collet held in this position, tubing is pulled straight out. Generally, both fitting and tubing can be re-used. Push-in fittings have found their place in the water industry. Their most common use is for general tubing connections in RO and water filtration systems.
