VACUUM semi-automatic self cleaning screen filters are designed for filtration of liquids with solid particles and colloidal materials. Special suction pads ensure the complete cleaning of the screen with minimum water consumption and without stopping the filtration process. They can be supplied in three different building configurations (Y, L, and O) depending on the position of In/Out connections. The filtering cartridge can be supplied either as a polyester mesh inserted between two AISI 316 net tubes or as a three layer AISI 316 stainless steel cartridge (REPS); with this solution the filtration degree ranges from 25 µm to 810 µm. All filters are supplied ready to work, with drain valve and pressure gauges included.
