WebContamination by air- and water-borne particles can severely impact your equipment’s cycle time and performance, resulting in loss of power and reduced heat dissipation. Milky-looking hydraulic fluid is typically indicative of water contamination; foamy fluid is most likely contaminated by air. The causes of foaming are many. The most common include: 1. Water contamination 2. Solids contamination 3. Depleted defoamant (possibly due to the use of excessively fine filtration and electrostatic separation technologies) 4. Mechanical issues (causing excessive aeration of the fluid) 5. Overfilling of … See more Foam is a collection of small bubbles of air that accumulate on or near the surface of the fluid.
