AirCraft Motor For SG COMP04 Airbrush Compressor (SG COMP04-08)
At a Glance: Replacement motor assembly for SG COMP04—restores power, smooth operation and reliable pressure build.
When an airbrush compressor stops starting, loses power, overheats, or becomes noisy and inconsistent, the motor is often the core component to inspect. The AirCraft SG COMP04-08 Motor is a replacement motor assembly designed for the SG COMP04 airbrush compressor. It’s the drive unit that powers the compression cycle, turning electrical energy into the mechanical motion that builds air pressure. Replacing a worn or failed motor can bring your compressor back to life—restoring dependable airflow for clean, consistent airbrushing without stalling, surging or frustrating downtime.
Bring The Compressor Back To Life: a replacement motor that restores dependable air supply
Motors can fail due to wear, overheating, electrical faults or contamination. A correct replacement motor helps restore the compressor’s output and stability, keeping your airbrush setup reliable for detailing and fine spraying.
Extra Information
Before replacing the motor, check simpler causes such as the power switch, plug/cord, and airflow restrictions that can overload the unit.
Ensure ventilation openings are clear—restricted cooling can shorten motor life.
Pro Tip
If the compressor has been running hot, inspect the head/valve plate and linkage for binding. A motor can fail early if the mechanism is tight or misaligned.
