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 gravity 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 chemical.
