Product Overview
The Master Airbrush Cordless System consists of two primary units: the air compressor and the dual-action airbrush, complemented by various accessories.
Air Compressor
- Power Button: Activates and deactivates the compressor.
- LED Display: Shows current airflow level (P1-P4) and battery charge status.
- Airflow Adjustment Button: Cycles through four airflow speed settings (P1: Low, P2: Medium, P3: High, P4: Extra-High).
- USB-C Charge Connector: For recharging the internal Lithium-Ion battery.
- Airbrush Holder: Conveniently stores the airbrush when not in use.
Dual-Action Airbrush
- Trigger: Controls both air and fluid flow. Pushing down releases air; pulling back releases fluid.
- Nozzle Cap: Protects the needle and nozzle.
- Fluid Cups: Interchangeable cups for holding paint.
- Preset Control Knob: Located at the rear of the airbrush, this knob limits the backward travel of the trigger, allowing for consistent line thickness.
- Quick Flush Cutaway Handle: Enables quick access to the needle chucking nut for flushing and cleaning air passages.



Setup
- Charge the Compressor: Before first use, fully charge the compressor using the provided USB-C cable and a 2A or 3A fast charger. The LED display will indicate charging status. A full charge takes approximately 35 minutes.
- Attach Air Hose: Connect one end of the 4-foot air hose to the air outlet on the compressor and the other end to the airbrush. Ensure connections are secure to prevent air leaks.
- Select and Attach Fluid Cup: Choose the appropriate size fluid cup for your project and screw it onto the top of the airbrush.
- Mount Airbrush Holder (Optional): The airbrush holder can be attached to the side of the compressor for convenient storage.
Operating Instructions
- Prepare Your Paint: The 0.4mm tip is suitable for light to medium viscosity acrylic paint, makeup, water-based paint, food coloring, or other liquid media. Thicker paints may require dilution. Test paint consistency on a scrap surface before applying to your project.
- Fill the Fluid Cup: Use the eyedropper to carefully fill the selected fluid cup with your prepared paint. Do not overfill.
- Power On the Compressor: Press the power button on the compressor. The LED display will show the current airflow level (P1 by default).
- Adjust Airflow: Press the airflow adjustment button to cycle through the four pressure settings (P1 to P4) to achieve the desired air pressure for your application (20 to 36 PSI).
- Begin Spraying:
- Hold the airbrush approximately 2-6 inches from your surface.
- Push down on the trigger to start airflow.
- While maintaining airflow, gently pull the trigger back to release paint. The further back you pull, the more paint will be released.
- Adjust the preset control knob at the rear of the airbrush to limit trigger travel for consistent lines.
- Move the airbrush smoothly and consistently across your surface.
- Stop Spraying: Release the trigger forward to stop paint flow, then release the trigger upwards to stop airflow.
- Power Off: Press the power button on the compressor to turn it off when finished.

Maintenance
Proper cleaning and maintenance are crucial for the longevity and performance of your airbrush system.
After Each Use:
- Empty Fluid Cup: Remove any remaining paint from the fluid cup.
- Rinse: Fill the cup with an appropriate cleaning solution (water for water-based paints, specific cleaner for acrylics/makeup). Spray the cleaner through the airbrush until it runs clear.
- Back-Flush: Place your finger over the nozzle cap and pull back the trigger. This will force air back into the fluid cup, bubbling and cleaning the inside of the cup and paint passage. Repeat with fresh cleaning solution.
- Clean Needle and Nozzle: Use the provided cleaning brushes to gently clean the inside of the fluid cup and around the needle. For thorough cleaning, you may need to remove the needle and nozzle (refer to the detailed diagram in the manual for component identification).
- Wipe Down: Wipe the exterior of the airbrush and compressor with a clean, damp cloth.
Regular Maintenance:
- Periodically lubricate the needle packing with airbrush-specific lubricant.
- Inspect O-rings for wear and replace if necessary (spare O-rings are included).
- Store the airbrush and compressor in a clean, dry place.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No air flow | Compressor not powered on; low battery; air hose disconnected. | Ensure compressor is on and charged; check air hose connections. |
| No paint flow | Clogged nozzle; paint too thick; needle bent or stuck; empty fluid cup. | Clean nozzle and needle; dilute paint; check needle for damage; refill cup. |
| Splattering or inconsistent spray | Paint too thick or thin; air pressure too high or low; partially clogged nozzle; damaged needle. | Adjust paint consistency; modify air pressure; clean nozzle; inspect/replace needle. |
| Air leaks | Loose connections; damaged O-rings. | Tighten all connections; inspect and replace O-rings if damaged. |
| Compressor battery drains quickly | Continuous high-pressure use; battery degradation over time. | Use intermittently for longer operation; ensure full charge before use. |
