Vacuum pumps have air and oil filters which will also require maintenance work.
Oil filter must be replaced every time the oil is changed and outlet filters every 9 to 18
working months. It will only have to be replaced if blocked with solids or with burnt oil.
The following symptoms will indicate that filters are blocked:
-Oil vapour existence at outlet
-Increase in the electrical consumption of the engine
-Oil leakage though air valves (if there is any)
In some cases, a big blockage in the filter can cause a filtering element to
brake.
You can also include a manometer in the pump (optional) which indicates outlet
filter load losses and so its level of pollution.
