Filter, Becker, U Series, Part# 74000101000

This is a replacement filter cartridge for Becker U Series oil-lubricated rotary vane vacuum pumps. It sits at the pump’s air intake and cleans the air before it enters the pump . Think of it as a guard at the front door. It stops dirt, dust, and other particles from getting inside where they can cause damage. This specific filter, part #74000101000, fits two Becker pump models. It works on the U4.20. It also works on the U4.40 . If you have either of these pumps, this is the right filter for you. It is also used as part of major overhaul kits for these pumps . This filter works really well. It catches 99 out of every 100 particles that are 2 microns or larger . To give you an idea, a human hair is about 70 microns thick. So 2 microns is very, very small. This filter grabs dust that you cannot even see with your eyes
