When to Change a ProVent filter

ProVent 200 Catch Cans do a remarkable job of filtering oily crank case fumes from entering the inlet area. One of the common mistakes people make is not replacing the filter, or not knowing when to change a ProVent filter.

Depending on the age and condition of the engine the ProVent Filter will be good from anywhere from 20,000km to 40,000km. Yes, this is a big window of difference, however once you replace the first filter, the ongoing filters will usually last a lot longer.

Maintaining a ProVent 200 Catch Can

  • Check it has been installed correctly with no kinks or poor fitting clamps
  • Remember to regularly drain the excess hose. We recommend doing this every 5,000km. If the excess hose is not drained, it can collect enough oil to fill the can with waste oil and this will stop it from filtering correctly
  • In the cooler months you may find some water condensation in the filter. This is nothing to be alarmed about
  • The filter can be dripping with oil. This is perfectly normal. This does not mean it needs replacing

When does the ProVent Filter need changing?

There is no specific time frame listed for when to change a ProVent filter. Usually once the filter has reached around 20,000km, it’s time to make a closer inspection.

Firstly, inspect the outside of the can for any oily residue. This is the tell-tale sign that the filter needs replacing. When the filter is unable to work correctly, oily residue releases from the pressure valve in the can lid and begins coating the outside of the can. This oily residue on the outside of the can is easily noticed. It is now time to replace the filter.
