Paint Repair Equipment - Air Compressor
1. Air Compressor

The air compressor is one of the most important pieces of equipment used in paint repair.
An air compressor is a machine that squeezes air and raises its pressure, enabling you to use spray guns and other air powered tools.
Select the compressor type to meet your shop's requirements. Air compressors are classified as follows:

Number of Compression Stages
Stages
Single Stage Pressure
Dual Stage Pressure
Application
Use when compressed air consumption is comparatively small.
When air pressures exceeding 980 kPa (10 kgf/cm2, 142 psi) are constantly required. Also best when constantly using multiple high consumption air tools, or when air supply pipes are very long.

Control Method
Method
Start/Stop
Load/Unload
Operation
Intermittent Operation
Continuous Operation
Feature
The motor shuts off when the air pressure exceeds its specified value, and it resumes its operation automatically when the pressure drops below the cut-in pressure.
This is suitable for applications where a single operator operates an air toll repeatedly with the air pressure ranging from 785?980 kPa (7?10 kgf/cm2, 114?142 psi).
Unloader valves allow no-load compressor operation when the air pressure exceeds a prescribed level. The compressor begins developing air pressure when the air pressure drops below the cut-in pressure.
This is suitable for continuous and simultaneous use of several air tools with the air pressures ranging from 490?686 kPa (5?7 kgf/cm2, 71?100 psi).
Compressor Installation Location:
Should be located on a level floor and protected from rain or other water sources. The location should also have adequate ventilation and avoid excessive humidity and dust.
The location’s temperature should remain under 104 °F (40 °C), even during the hottest weather. Direct sunlight should be avoided.
There should be enough space for maintenance and inspection. Maintain a distance of 30 cm (12 in), or more, from the wall.
If the compressor is located inside the workshop, it must be an explosion-proof type to prevent fire and explosion hazards.
Inspection of Compressor: Daily Check
Oil Level Check
Open drain valve to remove water from tank
Especially when using dual-component polyurethane resin coatings, you may need to open up the drain valve and drain the water and oil inside the tank more often because the hardener will react with water inside reducing the paint film’s performance.

Monthly Check:
Clean intake air filers
Check safety valve operation
Check the drive belt tension

Monthly Check:
Change compressor oil
