The WM300 TOP filtration unit can be used for water recirculation in swimming pools, ponds, spas, and whirlpools. Sand filters work on the natural principle of water filtration. Water passes through a layer of sand that traps fine impurities. Over time, the sand becomes clogged and needs to be backwashed, which is done using the six-way valve. By turning the valve to the sand backwash position, the direction of water flow changes and the trapped dirt is flushed out to waste. This process can be repeated throughout the entire service life of the sand, which is very long compared to other filtration methods. The WM300 TOP sand filtration unit, 4 m3 / h, consists of a sand filter tank, a pump with a hair prefilter, a 6-way valve, and a base (pallet). The WM300 TOP filtration unit is delivered disassembled. It must be assembled before connecting it to the pool. Installation and commissioning are simple. The filtration unit can be connected to the pool circuit by gluing it to PVC pipes or flexible hoses with a diameter of 50 mm.
