Cee dee vacuum equipment provides hydraulic oil cleaning pump. These hydraulic oil cleaning pump is capable of removing contaminants of size as small as 0.01 u and cleaning the oil up-to nas level 4-5, ie, better than new oil [new oil nas level is nas 9-12], giving trouble-free j operation and maintenance-free units. This pump make use of electrostatic precipitation to remove sub- micron particles of insoluble material, without effecting soluble oil additives. Tiny particles are electrostatically driven to, and then captured on, the positively or negatively charged walls of electrodes. Large particles
