Equivalent of (Velcon) Coalescing Filter Cartridge

The coalescing filter element is used to filter out solid particles and colloidal substances in the working medium and effectively control the pollution degree of the system. The filtrate does not enter the filter from the inlet of the filter, and after the filter element intercepts impurities, the filtrate flows out from the outlet and enters the clear liquid storage tank. With the progress of filtration, the filter cake layer becomes thicker and the filtration resistance increases. When the set pressure difference is reached, the filter element needs to be back washed. First, close the liquid inlet and outlet, introduce compressed gas into the tank, and filter the residual hydraulic pressure in the filter tank. When backwashing the filter column, compressed gas is introduced into the filtered liquid outlet of the filter to inflate the filter cloth, so that the intercepted filter cake and impurities in the gaps of the filter cloth fall off and are discharged from the lower discharge port.
