Compressor Maintenance (VIDEO)

Keep your air compressor running smoothly with preventative maintenance.

Keep Fins and Radiator Clean

Depending on how often you use the machine, once every few weeks or once a month, you should flush out the radiator fins.

You can pressure wash them from the outside in — it's not going to hurt anything, especially on the Rotair compressors.

Some of our older machines come with APT compressors, on which the alternator is right behind the radiator. If you plan to pressure wash the radiator fins on an APT compressor, simply put a piece of cardboard in front of the alternator to protect it.

You can always use compressed air instead, and not worry about protecting the alternator.

Prolong the life of your air filter

All compressors have air intake filters, which are to be changed at regular service intervals. If you are not yet due for a change but notice your machine running poorly (i.e. losing pressure), you should check the air filter.

Simply remove the filter cartridge and shake excess dust or debris off. Using compressed air is too harsh on these filters as they are just made of paper.

This will help the compressor maintain a good running pressure until it's time to change the filter.
