during the process of water flowing into coarse mesh filter from inlet tube, and then flowing out through fine-mesh filter, impurities in water will gradually accumulate at the surface of filter, which makes pressure difference come into being between outlet and inlet. because coarse mesh filter can remove fairly large particles，thus fine-mesh filter shall avoid being damaged by them.

filter is equipped with pressure difference switch and integrated controller. when pressure difference reaches default value, or preset backflush interval time has reached, controller shall enter into backflush program. but additional functions can be added in according with requirements of consumer, such as, open bypass, shut water pump, raise the alarm and so on when water filter breakdown.

auto-cleaning
drainage valve shall open automatically when preset pressure difference reaches its default value, or backflush interval time has reached. that is, backflush program starts up.

backflush suction which driven by motor shall make screw rotation on the surface of fine-mesh filter, so foreign particle accumulated on the surface of filer mesh can be absorbed into suction by backflush, then flow out by drainage valve. backflush duration is between 40 seconds and 1 minute.
