Vacuum Filters

Vacuum filters primarily work on Vacuum principle. Vacuum is created in a chamber by pump suction or ventury. The chamber forms the bottom portion of tank which receives the dirty fluid from machine. Filter media ( paper / mesh ) is laid on top of this chamber. Fluid passes through media to chamber. Dirt is collected on the media. When media chokes, vacuum increases which is sensed by switch. Dirt media is pulled out by geared motor.
