Hydraulic Filtration Knowledge
Zerospark: the antistatic filter
zerospark is the innovative product created to solve the problem of electrical charge in hydraulic filters due to the passage of oil through the filters This issue can result in damage to filter elements, oils and circuit components. It can even cause fire hazards in environments where flammable materials are present.

FROM CHARGE BUILD-UP TO DISSIPATION
THE TRIBOELECTRIC EFFECT
The body with the most electronegativity strips electrons from the other, generating a build-up of net negative charge on itself. The other body is charged by the same amount but with the opposite sign, giving rise to very high potential differences. These, if not dissipated, can give rise to electrostatic discharges.
CHARGE RELAXATION
Here are several methods to dissipate charge. One is charge relaxation, in which the pipes and specific other parts of equipment are made conductive. The charge build up then flows away along defined path ways in the equipment.
Dissipative filter elements
To solve the problem of charge build-up in filters, MP Filtri has developed an innovative solution. By replacing certain insulating components with conductive zerospark versions, the charges on the media are free to move towards the head and are thus dissipated to the ground.
Benefits
- Elimination of triboelectric effect
- Dissipation of accumulated charges
- Improved performance over time
- Increased safety
- Resistance to cyclic flow
- Weight and cost optimisation
