- Do not expose the compressor to rain, moisture, or extreme temperatures.
- Ensure the power supply matches the compressor's requirements (230 Volts).
- Keep children and pets away from the operating compressor and its accessories.
- Disconnect the compressor from the power source before performing any maintenance, cleaning, or when not in use.
2.2 Electrical Safety
- Do not use the compressor with a damaged power cord or plug. If damaged, contact qualified personnel for repair or replacement.
- Avoid overloading electrical outlets. Use a dedicated circuit if possible.
- Do not operate the compressor if it shows any signs of electrical damage or malfunction.
2.3 Operational Safety
- The compressor features integrated thermal protection, which automatically shuts down the motor to prevent overheating. Allow the unit to cool down if this occurs.
- An additional safety element protects the air tank from overpressure, ensuring safe operation within specified limits.
- Do not exceed the maximum operating pressure of 3 Bar.
- This compressor is oil-free, eliminating the risk of air contamination from oil particles.
3. Product Overview and Components
The WilTec AS176 is a compact, portable, and oil-free airbrush compressor designed for quiet and efficient operation. Its robust construction ensures durability and consistent performance.

3.1 Main Components
- Compressor Unit: The main body housing the motor and pump, featuring active cooling via an integrated fan.
- Pressure Gauge: Displays the current air pressure in both Bar and PSI for precise control.
- Pressure Regulator Knob: Used to adjust the output air pressure to suit different airbrushing needs.
- Air Outlet: The connection point for the air hose leading to your airbrush gun.
- Power Switch: A simple ON/OFF control for the unit, typically located on the side.
- Carry Handle: Integrated into the top for easy transport.
- Moisture Trap: An essential accessory (often included) that filters moisture from the compressed air, preventing water from reaching your airbrush and affecting your work.

4. Setup
- Unpacking: Carefully remove the compressor and all accompanying accessories from their packaging. Retain the packaging for future storage or transport.
- Placement: Place the compressor on a stable, level, and clean surface in a well-ventilated area. Ensure there is adequate space around the unit for proper air circulation and cooling.
- Connect Air Hose: Connect one end of the air hose (e.g., 5-meter hose) to the air outlet on the compressor. If using a moisture trap, connect it inline between the compressor and your airbrush gun to ensure dry air delivery.
- Connect Airbrush: Attach your airbrush gun to the other end of the air hose. Ensure all connections are secure to prevent air leaks.
- Power Connection: Before plugging in, ensure the power switch on the compressor is in the "OFF" position. Then, plug the power cord into a suitable 230V electrical outlet.

5. Operating Instructions
- Power On: Flip the power switch to the "ON" position. The compressor will immediately begin to build pressure.
- Adjust Pressure: Use the pressure regulator knob to set the desired working pressure for your airbrushing task. Turn the knob clockwise to increase pressure and counter-clockwise to decrease it. The pressure gauge will display the current output pressure.
- Automatic Start/Stop: The compressor is equipped with an automatic start/stop function. It will automatically turn off when the set pressure is reached and turn back on when the pressure drops during continuous use, ensuring consistent airflow without constant manual intervention.
- Airbrushing: Once the desired pressure is set, you can begin your airbrushing task. This compressor is suitable for airbrush guns with nozzle diameters typically ranging from 0.2 mm to 1 mm. Please note that using larger nozzles may require higher pressure and air flow for optimal performance.
- Power Off: When you have completed your airbrushing session, turn off the compressor by flipping the power switch to the "OFF" position.
- Depressurize: To release any remaining air pressure from the system, trigger your airbrush gun until the pressure gauge reads zero. This helps to relieve stress on the system components.
6. Maintenance
Regular maintenance is crucial for ensuring the longevity, reliability, and optimal performance of your WilTec AS176 compressor. As an oil-free unit, it requires minimal maintenance.
6.1 Daily Maintenance
- After each use, drain any accumulated moisture from the moisture trap. This prevents water from entering your airbrush and ensures clean air delivery.
- Wipe down the exterior of the compressor with a clean, dry, soft cloth to remove dust and paint residue.
6.2 Periodic Maintenance
- Inspect the air hose regularly for any signs of wear, cracks, kinks, or leaks. Replace the hose if any damage is observed to maintain consistent air pressure.
- Check all connections (hose to compressor, hose to airbrush, moisture trap connections) to ensure they are secure and airtight.
- Since this is an oil-free compressor, no oil changes or lubrication of internal components are required, simplifying maintenance.

7. Troubleshooting
This section provides solutions to common issues you might encounter with your WilTec AS176 compressor. For problems not listed here, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Compressor does not turn on. | No power supply; Power switch off; Thermal overload activated. | Check power cord connection and electrical outlet; Ensure power switch is in the ON position; If overheated, allow the compressor to cool down for 15-30 minutes. |
| Low or no air pressure output. | Air hose leak or kink; Pressure regulator set too low; Clogged airbrush nozzle. | Inspect air hose for damage and ensure connections are tight; Adjust the pressure regulator knob clockwise to increase pressure; Clean your airbrush nozzle thoroughly. |
| Compressor runs continuously without stopping. | Air leak in the system (hose, connections, airbrush); Regulator set to maximum pressure or faulty. | Check all air connections for leaks (listen for hissing); Adjust the regulator to a lower working pressure; If problem persists, contact support. |
| Excessive noise or vibration during operation. | Loose components; Compressor placed on an uneven or resonant surface. | Check for any loose screws or parts and tighten them; Place the compressor on a stable, level, and possibly padded surface to absorb vibrations. |
