How Do I Maintain My Piston Air Compressor?

There are crucial reasons why you should service and maintain your compressor regularly, with the most common issues being piston failure caused by wear of components, increased friction, corrosion, reduced cooling, overheating bearings and components, clogging of air filters.

You may find that your piston compressor has low performance and higher energy result by lack of maintenance, as well as a limited operation range; all due to the piston compressor oil oxidising over time! We have carefully selected the best compressor oil air air filter for the job.


We recommend that you service your compressor every six months!

It's easy and you can do it yourself.
