Filter is makes up by shell, multiple filter core, anti-flush institution and differential pressure control device

　　Generally speaking, profession grease filter factory had produced filter products into four main parts, such as the shell, multiple filter core, anti-flush institution and differential pressure control device. Professiongrease filter factory had use the diaphragm plate to divide the inner capacity of shell body into upper and down capacity, and there are several filter core had been installed on the upper capacity to ensure the biggest filtering space but the smallest filter volume, and grease filter factory had install the anti-flush sucking disc on the down capacity.

　　So when the filter is working, dirty water would through the wholesale grease filter inlet to flowing into the filter down capacity and through the diaphragm plate to enter into the inner capacity of filter core. As long as the size of impurity is bigger than filter core gap, it would been hold back, so the clean liquid can cross the filter gap and get to the upper capacity, then discharge out through the exit at the end.
