Filter used the high strength wedge shape filter screen

　　To ensure the best filtering effect, more and more profess grease filter factory decide to use the high strength wedge shape filter screen to produce filter products, through to control the pressure difference into the suitable arrange and timed control fully automatic clean filter core, so when the exit and inlet pressure difference is bigger than setting value due to lots of impurities had been hold back on the filter core surface, or the timer device has get to the setting time, then the electric operated control box would send out the signals to driving the anti-flush institution.

　　When the anti-flush sucking disc is opposite to the filter core inlet, profession grease filter factory said the dirty water discharge valve would be open and he system would start to release pressure and discharge water out, so profession grease filter factory said there would exist a relative pressure between the sucking disc and filter core, which is smaller than filter core external negative pressure zone, which can be used to press the clean water to flowing into the filter core internal from the external, all impurities grains would been discharged out through the discharge value.
