Changing the compressor filter is an important part of regular maintenance and must be carried out correctly. First, make sure that the compressor is safely shut down and cooled down before performing the filter change. Then, consult the user manual to find the filter replacement procedure. Usually, the filters are located in an accessible position outside the compressor. The old filter must be carefully removed and replaced with a new filter. The frequency of filter replacement varies depending on the operating time of the compressor, the conditions of use and the manufacturer's recommendations. On average, a replacement frequency of between 3000 and 4000 hours is recommended, but more frequent changes may be required if there is intensive use or heavy duty conditions. Periodic filter replacement improves the efficiency and performance of the compressor and ensures a long service life.
