### Air Compressor Inspection Checklist

Please complete the inspection checklist for the air compressor.

#### Inspection Items

##### Lubrication & Filters

- **Oil Level:** Check that lubricant oil level is within the safe range (via sight glass or dipstick) and no obvious oil leaks. Ensures proper lubrication to prevent motor wear and costly breakdowns
  
- **Air Intake Filter:** Inspect the air filter element; ensure it’s clean and intact (not clogged or damaged).
  
- **Coolant level:** if applicable, check coolant level in radiator or tank.

|  | Pass | Fail | N/A |
| --- | --- | --- | --- |
| Oil Level |  |  |  |
| Air Intake Filter |  |  |  |
| Coolant level |  |  |  |

**Notes**  
##### Lubricant or oil change recommended?

#### Electrical & Motor

##### Electrical Connections

Visually inspect wiring, connectors, and terminals for secure connections, no exposed wires, and no signs of overheating (no discoloration or melted insulation). Secure, intact connections prevent electrical faults and hazards.

- Clear

**No data to display**

##### Motor Operation

Run the compressor briefly and listen for any unusual noises or vibrations from the motor or pump. Verify the motor runs smoothly without overheating.

- Clear

**No data to display**

##### Motor Safety Devices

Check that motor overload protectors or alarms (if equipped) haven’t tripped and are functioning.

- Clear

**No data to display**

#### Pressure & Safety Devices

##### Pressure Gauge Reading

Note the system pressure on the gauge (psi or kPa) and ensure it is within normal operating range.

##### Pressure Switch Cut-off

Confirm the compressor cuts off at the intended maximum pressure and resumes at the cut-in pressure (pressure switch operates correctly).

- Clear

**No data to display**

##### Safety Relief Valve

Verify a spring-loaded safety relief valve is installed and unobstructed. If due for periodic test, carefully test its operation (momentarily lift or open it) to ensure it releases pressure properly.

- Clear

**No data to display**

##### Secondary Safety Controls

Check other safety shutdowns or alarms (e.g. high temperature shut-off, emergency stop) if the compressor has them.

- Clear

**No data to display**

#### Condensate Drains & Air Lines

##### Tank Condensate Drain

Drain the receiver tank’s condensate (water/oil) via the drain valve at the bottom. Ensure the drain valve itself is functioning (no blockage).

- Clear

**No data to display**

##### Moisture Traps/Drains (if equipped)

Drain the receiver tank’s condensate (water/oil) via the drain valve at the bottom. Ensure the drain valve itself is functioning (no blockage).

- Clear

**No data to display**

##### Air Leaks Detected?

- Clear

**No data to display**

##### Air Lines & Hoses Condition

Inspect distribution lines and hoses for damage, cracks, or abrasion. Ensure connections are tight and support/anchors are secure.

- Clear

**No data to display**

##### General Safety & Housekeeping

|  | Pass | Fail | N/A |
| --- | --- | --- | --- |
| All safety guards & covers in place |  |  |  |
| Emergency Stop switch test |  |  |  |
| Compressor is clean |  |  |  |
| Compressor is ventilated & free from obstructions |  |  |  |

**Other (describe)**

##### Mounting & Vibration

Check that the compressor is firmly mounted or bolted in place, and any vibration isolators are intact.

- Clear

**No data to display**

### About this template

An Air Compressor Inspection Checklist is a tool for technicians or facilities personnel to track and perform routine inspections and upkeep on air compressor systems. The checklist may cover filters, lubrication, pressure checks, electrical connections, drain valves, and air lines.

This form helps avoid costly repairs, reduce system downtime, and ensure safe operation. It may also support compliance ( [OSHA](https://www.osha.gov/laws-regs/regulations/standardnumber/1910), [ANSI](https://uploads.prod01.oregon.platform-os.com/instances/2032/assets/documents/pdfs/publications/ANSI_CAGIB19_1_2011final.pdf?updated=1700163022&utm_source=workyard.com)).

Fields may include:
- Oil levels, filter condition, and belt tension
- Leak detection and system pressure
- Motor and electrical connection checks
- Technician name and maintenance notes

Regular maintenance detects motor issues or leaks early, improves compliance and compressor efficiency.

Using this checklist can extend compressor lifespan and minimize performance interruptions.
