PALLsorb Filter Elements

Pall’s PALLsorb filter elements can be used to effectively remove as well as retain free and emulsified water contamination in hydraulic systems.

Water is one of the most common contaminants in industrial hydraulics – it reduces lubricating film thickness and causes corrosion, which can lead to serious problems.

 

When water contamination is neglected, it can cause fluid breakdown, including additive precipitation and oil oxidation, and accelerate metal surface fatigue. The presence of water also leads to the formation of ice crystals at low operating temperatures, causing components to jam.

 

Why Choose PALLsorb Filter Elements?

 

PALLsorb filter elements are your answer to water contamination woes in hydraulic systems. 

 

With an element collapse pressure rating of 100 psid (7 bar), PALLsorb hydraulic oil water filter are designed for high water retention without compromising on structural integrity. These advanced products are best-suited for removing water contamination from hydraulic and lube systems, cutting fluids, synthetic oils, and any other fluid system subjected to corrosion and wear from water.

 

A Pall Ultipor IIITM filter used upstream of the PALLsorb filter element enhances its service life and also protects the system from particulate contamination. We recommend that PALLsorb elements be placed in locations such as system return lines, ‘kidney’ loops on the reservoir, and on flushing units.
