Water distributor: make the unfiltered water flow evenly through the packing layer even under high flow rate and maintain a flat water surface on the packing layer.

Water collector: unique mushroom-shaped differential pressure compensation collector, so that the system in the state of filtration of all parts of the water pressure balance, high filtration flow rate, high efficiency; in the state of backwash, the formation of inner

In the backwash state, it forms internal circulation, with high backwash efficiency and no sand running.

Hand hole: The filter has two hand holes, one above and one below, which is convenient for installing and replacing the water distributor and collector, and the upper hand hole can be used for observing and refilling, while the lower hand hole can be used for emptying and maintenance.
