Hydac Patented Stat-X Filter Elements

Static Discharge Damage - In hydraulic systems, fluids with low conductivity result in friction between the fluids and the system components. This friction generates electrostatic discharges, which cause oil degradation, aging, varnish, and filter element burns. Oil degradation can lead to components (gears, bearings, valves, etc.) failing prematurely due to contamination and inadequate lubrication.





Hydac’s Patented Stat-X Filter Elements - Prevents both electrostatic buildup and discharge, under virtually all operating conditions, including:

Low-temperature cold start

Extremely low oil conductivities

(Group II & III Base Stocks, ex: used in Power Generation circuits)

High flow flushing operations

Hydraulic loads well above 0.02 L/min/cm2



By mitigating electrostatic discharge, oil degradation, filter element damage, and component failure are decreased. This results in significant cost saving due to increased time between service intervals (fewer maintenance dollars) and longer component and oil life. Also, safety for both employees and machines is also significantly enhanced.
