This image highlights the main features of the compressor: the air pressure adjustment regulator knob with its gauge, the built-in airbrush holder, the built-in handle for portability, and the 6-foot braided air hose with the mini in-line moisture filter.

This image provides a closer look at the included accessories and controls: the in-line moisture filter trap, the 6-foot air compressor braided hose, and the simple interface with an adjustment knob and pressure gauge on the compressor unit.
5. Setup Instructions
- Placement: Place the compressor on a stable, level surface in a well-ventilated area. Ensure there is adequate space around the unit for air circulation.
- Connect Moisture Filter and Hose: Attach the mini in-line moisture filter to the compressor's air outlet. Then, connect the 6-foot braided air hose to the moisture filter. Ensure all connections are secure to prevent air leaks.
- Connect Airbrush: Attach your airbrush to the free end of the braided air hose.
- Power Connection: Plug the compressor's standard 3-prong power cord into a grounded 120-volt electrical outlet.

This image shows the coiled 6-foot braided air hose, which is used to connect the airbrush to the compressor. It features metal connectors at both ends.

This image provides a close-up view of the mini in-line moisture filter, a cylindrical silver component with a clear section to observe collected moisture. This filter is crucial for delivering dry air to the airbrush.
6. Operating Instructions
- Power On: Flip the power switch to the "ON" position. The compressor will begin to run and build pressure in its internal tank.
- Adjust Air Pressure: Use the air pressure adjustment regulator knob to set the desired working pressure. Observe the gauge to monitor the pressure. The compressor delivers air with constant pressure and minimal pulsation due to its small air tank.
- Begin Airbrushing: Once the desired pressure is set, you can begin using your airbrush.
- Automatic Shutoff: The compressor features an automatic shutoff function. It will stop running once the maximum pressure is reached and restart when the pressure drops below a certain threshold, conserving energy and reducing wear.
- Power Off: When finished, turn off the compressor by flipping the power switch to the "OFF" position and unplugging it from the electrical outlet.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your compressor:
- Moisture Filter: Regularly check the mini in-line moisture filter. If water accumulates, drain it according to the filter's instructions. A clogged filter can restrict airflow and affect performance.
- Cleaning: Keep the exterior of the compressor clean and free of dust and debris. Use a soft, damp cloth for cleaning. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the compressor in a clean, dry environment when not in use.
8. Troubleshooting
If you encounter issues with your compressor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power supply; power switch off. | Check power cord connection; ensure outlet has power; turn power switch to ON. |
| No air pressure or low pressure. | Air leaks; clogged filter; regulator set too low. | Check all hose connections; clean or drain moisture filter; adjust pressure regulator knob. |
| Compressor runs continuously. | Air leak; automatic shutoff malfunction. | Check for air leaks in connections; if problem persists, contact support. |
| Excessive noise or vibration. | Unstable surface; internal issue. | Place on a stable, vibration-dampening surface; if noise is unusual, contact support. |
