Air compressor maintenance checklist

Regular compressor maintenance ensures your machine runs efficiently and with optimal output. Yet many businesses are unsure of the best way to create a practical maintenance schedule.

We’ve compiled this blog to help you create an effective compressor maintenance checklist – we’ll cover why maintenance is important, some maintenance tips, and a list of daily, weekly, monthly, quarterly, and yearly maintenance checks. 

Why is air compressor maintenance important?

1. Maintain efficiency

Scheduled compressor maintenance by trained engineers ensures that your compressor operates with maximum efficiency within the expected run time. Maintenance allows you to catch any issues early enough before they become a significant problem which might lower your compressor’s capacity. This also increases the lifespan of your compressor. 

2. Safety 

Lack of maintenance can lead to internal corrosion or blocked valves, which can cause significant and dangerous issues. Preventive maintenance checks allow you to catch issues early on and keep your team safe whilst working.

3. Compliance and warranty 

Regular compressor maintenance and servicing ensures that you comply with health and safety regulations and prevents you from voiding your compressor’s warranty. 

4. Reduce downtime 

Maintenance can reduce the likelihood of future repairs and unplanned machine downtime. This helps ensure that your business isn’t interrupted by avoidable problems. 

5. Save money 

Sticking to a preventive maintenance schedule will save time and money in the long run. There’ll be less chance of a breakdown where your compressor is out of action, impacting your business. A faulty compressor can also lead to higher energy costs that harm your business.

Air compressor maintenance tips 

1. Read the user manual

Reading the user manual is the easiest way to determine how to maintain your air compressor. This should tell you how to clean your equipment and replace any faulty parts. You should always follow the recommended maintenance and servicing schedule. 

2. Regular cleaning 

Cleaning is an integral part of compressor maintenance that helps ensure your equipment functions effectively. You should regularly dust all surfaces, remove debris, and clean residual oil. 

3. Scheduled checks and inspections 

It’s best practice to create a personalised checklist for your compressor or compressed air system comprising daily, weekly, monthly, quarterly, and yearly checks. This will ensure that all checks are carried out to ensure your machine is in optimal condition. 

We cover some of the most important checks to include in your maintenance checklist below. 

Daily air compressor maintenance checklist 

  • Check the oil levels. 
  • Check the cooling air flow is clear and if there are any obstructions to the vents or filters.
  • Empty condensate from the receiver tank, filters, and dryers (or use timed or zero-loss valves to automate this process).
  • Check the guards are in the correct position.
  • Check the belt tension (if fitted).
  • Inspect the machine for visual signs of damage and leaks.
  • Ensure the compressor will not overheat or freeze overnight where it is stored. 

When the compressor is running: 

  • Check it is running correctly.
  • Listen for any unusual sounds or noises.
  • Check the pressure switch is working and the machine is shutting off when the operating pressure is reached.

Weekly air compressor maintenance checklist 

  • Check display readings.
  • Check the air filters and clean or replace them.
  • Inspect the hoses. 
  • Check that condensation is being discharged during operation. 
  • Inspect coolers.
  • Check the temperature.
  • Check filters and dryers (if relevant). 
  • Check the pressure dew-point temperature (for compressors with integrated dryers).

Monthly air compressor maintenance checklist 

  • Check and tighten all bolts and fasteners.
  • Check connections for leaks.
  • Check the safety relief valve.

Quarterly air compressor maintenance checklist 

  • Remove and inspect air filter elements. Replace it if necessary due to damage or contamination. 
  • Clean intake valves.
  • Check run hours and if you are due a service (after 2000 hours).
  • Change the oil filter (after 2000 hours).

Yearly air compressor maintenance checklist 

  • Service your compressor (if your compressor needs servicing).
  • Change your air/oil separator (after 4000 running hours).
