If you are thinking about maintaining your air compressor, do not think to perform a standard form of maintenance.

To assure the steady run of operations of your air compressor, you need to operate a preventative form of maintenance.

Either you own one or multiple air compressors, you must observe and check your compressors frequently. Otherwise, immature failing and expensive repairs can take place.

Following a preventative air compressor maintenance guide prevents interruptions and accidental downtime.

Below we have given a complete preventative routine guide for five different types of air compressors. Just find out which routine direction is suitable for your air compressor.

6 Crucial Parts of Your Air Compressor to Inspect

Air Filter

The primary function of your air compressor is to provide you clean, pure, and compressed air. And to get that clean air, the air that goes into your compressor needs to be always filtered.

This job can only be done with a clean, flawless air filter.

However, if the air filter becomes dirty then pollutants, impurities can affect your air compressor badly.

To avoid this situation, you must check the air filter daily for cleaning. Replace it if necessary.

Air Intake Ventilation

You need to take care of the ventilation air inlet ducting of your air compressor. This component’s temperature can’t be dropped below the freezing point; otherwise, your whole system can freeze-up.

Moreover, the freezing can damage the cooler and disallow the start or shut down your air compressor completely.

Observe the intake vents every week and clear them if needed. It will also prevent dirt or impurities from entering your air compressor system.

Oil Filter

Oil can reduce the performance quality of your air compressor if it passes to the end of an operation, for example, pneumatic spray painters, air cleaner, or in any application where the oil can affect the surface.

So, it is essential to remove the oil from your air compressor before the air comes out of the machine.

Whether you have a lubricated or no-lubricated air compressor, inspect the oil filter once in a week. If your air compressor’s oil filter gets concealed with oil residue, then replace it quickly.


Check for the belts if they have proper tension. The belt’s rubber needs to be flexible and firm.

However, after much time of use, the belts get to wear down and crack in some specific places. So, before they lose their tension or break at the time of operation, you need to change them.

Weekly examine the belts to know if they start to wear. Correct the tension if needed, and replace them if you notice some cracks on them.


Lubricants are used to smooth and remove the corrosion movement of all the internal metal parts and connectors.

Without lubricant, your air compressor’s internal parts and joints get corrosion and damage some specific mechanical parts in no time.

Old and low viscosity lubricants can also make your air compressor corrosive and damaged.

You need to inspect the lubricant level daily to protect your air compressor. And every six months, replace the old lubricants with a fresh coat.

And one thing to keep in mind, change the separator element also while replacing the lubricants.

Motor Bearing

If you saw a motor bearing, you might notice that some tiny little balls are rolling around each other, and also around the round encasement of the interior walls.

For a smoother run of the motor and to prevent it from rust, you must lubricant it accordingly.

In every 4000 hours, grease them. It will indeed secure the performance and health of your air compressor motor.

While greasing, make sure if they get an adequate amount of lubricating. You may need to check at quarterly intervals in between every grease.
