The KIT MIDI 400 filtration unit can be used for water circulation in swimming pools, ponds, spas, and whirlpools. Sand filters work on the natural principle of water filtration. Water passes through a layer of sand, which traps fine impurities. Over time, the sand becomes clogged and needs to be backwashed, which is what the six-way valve is used for. By turning the valve to the sand washing position, we change the direction of water flow and flush the trapped dirt into the waste outlet. This process can be repeated throughout the entire service life of the sand, which is very long compared to other filtration methods. The KIT MIDI 400 sand filtration system, 6 m3 / h, consists of a sand filter tank, a pump with a hair strainer prefilter, a 6-way valve, and a base (pallet). The KIT MIDI 400 filtration unit is delivered disassembled. Before connecting it to the pool, it must be assembled. 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.

Operating PrincipleSuction is drawn from the main drain (1) at the bottom of the pool and from the skimmer(s) (2) at the water surface, and is carried through separate piping with the corresponding valves (3) by the pump (4) to the sand filter (5). After filtration, the water is returned to the pool through the return inlets (6), which are installed on the opposite side of the pool from the skimmer(s) and main drain. |
