This is a water purifier. It is designed to produce water that can be put into batteries. Hooks up to faucet. The filter may or may not need replacing. Filters are rated for 600 gal, but it depends on the amount of impurities in source water. This is good for battery operated forklifts, golf carts, etc. I'm sure it has many other uses where you need purified water. This unit cost over $500 new. Replacement filters are about $100. This can easily be mounted on wall and it has all the necessary hangers and fittings.
