Stat-Free® Filter elements against electrostatic discharges in hydraulic and lubrication systems

The trend of using ash-free hydraulic fluids, providing more compact systems and applying finer filtration, has led to an increase of electrostatic charging problems in hydraulic and lubrication systems during the last years.

In its new Stat-Free^® filter elements HYDAC combines excellent electrostatic features and filter performance for the first time. Through an innovative filter mesh and element design a very low charging of the filter element and the fluid during system operation is achieved, which has never been accomplished before.
