Filtration Group Filter Elements
Filtration Group E-Protect
The Filtration Group E-Protect is a high-performance filter elements for low conductive hydraulic and lubricating oils.
The FGC e-protect filter element made by Filtration Group, has been designed for use with low conductive hydraulic and lubricating oils (e.g. turbine lubricating oil in power plant technology). The filter element is distinguished by reliable conductivity, which has been registered for patent approval, as well as an element design that is optimized to suit electrostatic properties. The special element design prevents damage in the filter layers caused by electrostatic discharge.
Benefits of the Filtration Group E-Protect
- No disruptive discharge or damage in the filter material caused by electrostatic discharge.
- Reliable filtration during the entire service life of the element.
- Guaranteed equipment availability.
- Prevention of follow-up costs.
- Increase of oil service life.
- Prevention of follow-up cots.
- Prevention of varnish build-up on the element caused by electrostatic effects.
- No additional maintenance requirements needed because of direct compatibility with conventional filter elements.
- Reliable filtration in electrostatically critical applications.
- High dirt-holding capacity, defined filtration rate and efficient differential pressure properties.
Charge separation in fluid systems is a well-known phenomenon in high performance filters (filter fineness <10µm). Charge separation occurs during perfusion of the filter’s fine pores due to the viscous friction between the oil molecules and the surface of the fibre. Electron transfer takes place as a result of the close contact between the friction partners. The intensity and direction of the electron transfer depends on the material properties of the friction partners (triboelectric series). Depending on the electric properties of the filter material and of the oil, there is a subsequent charge equalisation or charge accumulation (after charge separation). With the fluids that have dominated the market so far, the charge separation is equalised again depending on the so-called relaxation time so that there are no noticeable effects in the fluid components including the filter elements or in the fluids (TRBS 2153). A significant increase of electrostatic charge within the fluid systems can have many causes
- Low retention time due to increasingly compact systems with low oil volumes
- Increasing filtration requirements, even in lubrication applications
- Increased application of environmentally-friendly zinc and ash free oils
