Filter has two open. The top one is used for observing and adding. The bottom one is used for clear and maintenance.
Each port adopts completely leakage design. System use the water pressure closed principles which is totally reliable.

Water distributor makes the unfiltered water flow evenly through filter layer even in high flow condition. And stay a flat
surface on filter layer.

Ball shell can fully help water distribution distribute water evenly. Cooperate 55 pcs mushroom mouth. Form internal loop
during backflushing. Sand is not leaving. The appearance of filter is composed of composites which has high pressure and g
ravity ratio and corrosion resistance. The ball shell integrally formed can bear 0.5Mpa pressure.

The special mushroom pressure difference compensate for the collector of filter which can keep each part water pressure
balance under filter condition for system. Filter flow is high and high efficient. It form internal loop during backflushing. High
efficiency and no sand leaving.

Inside of filter is made of black PE which can against environment pressure to prevent brittle fracture and no attacking by c
hemical.
