Air Compressor Maintenance Checklist
Ensure PSSR compliance and reliable pneumatic control with air compressor checks covering oil, filters, receiver drainage, and pressure relief testing.
What is an air compressor maintenance checklist?
A air compressor maintenance checklist is a structured list of the 12 preventive maintenance tasks — covering visual, functional, cleaning, safety and record-keeping checks — that keep an air compressor running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core air compressor checks
- Check compressor oil level and condition (oil-lubricated types)
- Drain moisture from the receiver tank
- Clean external surfaces and check for oil leaks
- Verify the pressure relief valve operates correctly
- Record running hours, oil condition, and pressure settings
What is an air compressor?
An air compressor provides compressed air for building services including pneumatic controls, BMS actuators, and workshop equipment. In commercial buildings, compressors are typically small to medium reciprocating or rotary screw units feeding a receiver tank and distribution pipework. Proper maintenance is essential for reliable pneumatic control valve operation and regulatory compliance under the Pressure Systems Safety Regulations.
This checklist is one of 34 in our HVAC maintenance checklists, covering air handling units, fan coils, chillers, VRF, ductwork and extract systems — filters, coils, refrigerant and damper checks.
Typical Air compressor maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.
Visual Checks
- Check compressor oil level and condition (oil-lubricated types)
- Inspect intake air filter for blockage or contamination
- Inspect drive belts (belt-driven models) for wear and tension
- Inspect pipework and joints for leaks
Functional Checks
- Drain moisture from the receiver tank
- Check the pressure switch cut-in and cut-out settings
- Listen for unusual noise or excessive vibration during operation
- Check compressed air dryer operation (if fitted)
Cleaning & Housekeeping
- Clean external surfaces and check for oil leaks
Safety Checks
- Verify the pressure relief valve operates correctly
- Verify the receiver has a current written scheme of examination
Record Keeping
- Record running hours, oil condition, and pressure settings
