Air Compressor Maintenance Checklist
Regular air compressor maintenance ensures your machine runs efficiently and with optimal output. Yet many businesses are unsure of the best ways to stay up to date with maintenance checks.
Our professionals have created this blog to help you tick off everything that’s part of an effective industrial 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?
Maintain efficiency
Scheduling trained engineers to complete regular compressor maintenance ensures that your compressor operates at maximum efficiency. Air compressor preventative maintenance allows you to catch issues early enough to avoid them becoming significant problems. This increases the lifespan of your compressor and reduces the risk of lowering your compressor’s capacity.
Safety
A lack of maintenance can lead to internal corrosion or blocked valves, which can cause significant and dangerous issues. Maintenance checks provide an opportunity to find these issues before they pose a risk to the team using and working around the machine.
Compliance and warranty
Regular maintenance and routine servicing help ensure that your air compressor complies with health and safety regulations and protects your compressor’s warranty coverage. This is because many regulatory standards outline that equipment must be regularly inspected and serviced to ensure it is safe for use and runs efficiently.
Reduce downtime
Regular maintenance lowers the risk of unexpected repairs and machine downtime, keeping your operations running smoothly and without preventable disruptions. Your production levels can remain steady this way.
Save money
Sticking to a preventive maintenance schedule saves both time and money over the long term. It minimises the possibility of breakdowns which could impact your business. It also ensures efficiency and cost-effectiveness, reducing high energy costs from unexpected repairs that harm your business.
Air compressor maintenance tips
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, notice any issues, and replace faulty parts. You should always follow the recommended maintenance and servicing schedule in the handbook.
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.
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 airflow 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/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. A service will be due after 2000 hours.
- Change the oil filter (after 2000 hours).
Yearly air compressor maintenance checklist
- Service your compressor.
- Change your air/oil separator (after 3000-4000 running hours).
