Vacuum Pump Filter

The present technology for vacuum pump filter uses electrostatic precipitation principle to filter out all the dust, mist, oily and gaseous particles in filter fluid stream which is going towards the vacuum pump.

The additional fixtures like flame proof panels and flame proof fixtures makes the filter effective for use in flame proof environment like:

- Solvent recovery systems;
- Semi conductor(s) process systems in Bulk drugs and pharma;
- Semi conductor(s) where fumes of explosive nature is produced.

Dry air from the object moves inside the vacuum pump filter. The current flow generates the electric field which in turn charges the particles present in the dry air. The electric field so produced leads corona generation (free electron generation). The free electrons so produced then combines with the gas molecules to from negative gas ions which subsequently gets collected at the charged collection plate. These ions in turn get transferred to the discharge electrode and the gas flows out through the plate precipitator.
