This exclusive media insures a very low charge across filter media over long periods of time to mitigate discharge sparking.
Electrostatic discharge (ESD) is a common problem with ash-free, zinc-free fluids. These modern oils have low electrical conductivity because they do not contain the heavy metals of previous generation fluids. Oil passing through hydraulic or lubricating systems filters can generate electrostatic charges which, when not dissipated, can lead to a high voltage spark from filter media to support tube. These sparks can lead to:
oil degradation and varnish
damage to components such as valves
potential damage to electronic components
potential explosions and damage to filter media
The consequences of varnish deposits are well-known, and include:
seized valve spools
shorter fluid life
SwiftDischarge™ media is available with all Swift Filter microfiberglass filter elements (Swiftglass products).
Anti-static SwiftDischarge Elements are suitable for power generation applications (gas turbines and power plants), plastic injection molding machines, mobile hydraulics, the pulp and paper industry and any other application that uses low-conductivity oils.
