A vehicle’s engine has an oil lubrication system. Likewise, it makes use of atmospheric air and consumes fuel. An engine can only perform for long periods by using clean fluids. Abrasive particles, whether of internal or external origin, contained within the moving fluids would cause major wear and damage to the engine. It is therefore necessary to reduce the size and quantity of such particles to a minimum. This is the essential function of filters.

Vehicles may also be fitted with a  cabin air filter separate to any air-conditioning system.

Filtration is a separation process consisting of separating the continuous component (liquid or gas) from the dispersed component (solid or liquid). This separation takes place as a result of pressure exerted on the suspension when the latter is pressed against a porous body.

The pressure drop, the efficiency and the lifetime determine filter’s performance, thus:  

  • THE PRESSURE DROP is the instantaneous pressure difference across the fluid input and output within the filter. It should be as low as possible.
  • THE EFFICIENCY of a filter is determined by the fineness of the filtration. An effective filter prevents premature engine wear. 
  • THE LIFETIME is determined by the quantity of contamination that can be screened before the filter ceases to function. 

All our filters meet these requirements but must be changed according to the Manufacturers’ recommendations or at least once a year.
