[AC Motor Maintenance Guide (For Air Compressor Operators)]

If your air compressor runs on an AC motor, this is a guide to show you how to keep the motor nice and efficient.

1. Daily / Regular Checks
*Keep it clean
Wipe off dust, oil, and dirt. Make sure the cooling vents are not blocked.
*Listen while running
Watch for unusual noise, vibration, or smell. Stop the machine if anything seems abnormal.

2. Weekly / Monthly Checks
*Check electrical connections
Make sure cables and terminals are tight and not damaged or burnt.
*Check motor temperature
The motor should feel warm, not extremely hot.
Overheating means something is wrong.
*Check mounting and alignment
Ensure the motor pulley is firmly mounted and properly aligned with the compressor pump's pulley.
3. Periodic Maintenance
Lubricate if required. Replace bearings if you hear grinding or whining noises.
Confirm voltage and frequency match the motor nameplate.
4. Safety Reminder
Always turn off and lock out power before inspecting or servicing the motor.
Regular checks help prevent breakdowns, improve efficiency, and extend motor life.

For Those Performing Grinding and Cutting Work 

Special training and certification are legally required in countries such as Japan when performing grinding or cutting work for professional purposes using pneumatic or electric grinders, rotary tools, or sanders.

For DIY or personal use, this training is not mandatory; however, it is strongly recommended to ensure operator safety and proper, efficient tool use.

Safety First!

UNOAIR Weekly Update 11/26/2025 Winter Lubricant for the Winter
2025-11-26
It is essential to change the pump lubricant in your air compressor to maintain optimal performance and extend its lifespan, especially considering the working environment and seasonal conditions.
Is your compressor ready for the cold winter?
 UNOAIR Weekly Update 11/19/2025 Air Tank and Your Safety
2025-11-19
Can an air compressor explode?
Yes—though it’s rare.
It usually happens due to:
• Over-pressure (failed pressure switch or blocked safety valve)
• Rust inside the tank from not draining moisture
• Overheating in poor ventilation
• Electrical faults or bad repairs
• Flammable vapors nearby
How to prevent it:
Drain the tank, keep good ventilation, avoid flammables, and check the safety valve.
Stay safe and maintain your compressor!
UNOAIR Weekly Update 11/05/2025 Are horsepower and tank capacity always accurate?
2025-11-05

A few months ago, a Japanese agricultural equipment trading company asked us to produce OEM air compressors.
We tested one of their current models, and the results were eye-opening:

  • The “2HP” pump actually produced around 1HP.

  • The “39L” air tank measured only about 32L.

In fact, many manufacturers and sellers display inflated specifications to cut costs.
It’s not uncommon to see 1HP labeled as 2HP, or 7.5HP as 10HP.

That’s why some customers ask,

“Why does Unoair’s 3HP compressor outperform others’ 5HP models?”

If you rely on accurate performance, it may be worth measuring your compressor’s actual tank capacity and air output.

UNOAIR Weekly Update 10/08/2025 Know You Compressor Pressure Switch and Safety Valve
2025-10-08
Low output? Frequent startups? Abnormal operation?
Check your pressure switch and safety valve first.
 
1. Purpose
The pressure switch and safety valve are vital for safe and efficient compressor operation.
Regular inspection prevents pressure-related failures and ensures stable performance.
 
2. Recommended Inspection Frequency
Normal use: Every 3 months
Heavy use: Every 1–2 months
After long downtime: Inspect before restarting
 
3. Pressure Switch Inspection
Power off: Always disconnect power and release air before inspection.
Check settings: Confirm ON/OFF pressures match specifications.
(Example: 0.8 MPa compressor → ON = 0.7 MPa / OFF = 0.9 MPa)
Test operation: Observe the pressure gauge to ensure proper stop/start timing.
Inspect terminals: Look for loose wires, corrosion, or dust.
Check internal wear: Replace or adjust worn copper contacts if needed.
 
4. Safety Valve Inspection
Check pressure: Ensure operating pressure doesn’t exceed the set limit (≈ 1.0 MPa).
Test manually: Lift the valve slightly to confirm air release.
Replace if stiff or unresponsive.
Check for leaks: Make sure no air leaks when the valve is closed.
Confirm setting: Set pressure should match the compressor’s max working pressure (typically 1.0 MPa).
 
5. Precautions
Always turn off power before inspection or adjustment.
Stop using the compressor if any abnormality is found and contact a qualified technician.
Keep inspection records for maintenance tracking and warranty support.
