Unlike the existing conventional filters, ZD series utilizes the principle of electrostatic ion. As the contaminated oil passes through the electrode, equipped with an electrostatic dielectric, various kinds of impurities in the oil are removed and attached to the dust collector. It is circulating purification system that only supplies only clean oil into the tank.

Zedal inc. provides the latest oil purifiers which eliminate impurities up to 10 micron during its first operation and separate moisture (20,000 ppm) secondly.

Normal filters are able to purify the particle size of 5 micron to the utmost. However, ZD series collects and removes 0.05 micron impurities with tertiary electrostatic ion system. As pre-maintenance equipment, ZD series will be the ACE in your factory since they prevent oil oxidation and maintain proper oil viscosity so as to supply clean oil.
