Key Features:
- Digital Display: Provides real-time pressure readings and allows for unit display adjustment (BAR, PSI, MPa).
- Adjustable Output Pressure: Allows setting the desired fill pressure up to 4,500 PSI (310 BAR).
- Automatic Shut-Off: The compressor automatically stops when the set pressure is reached.
- Automatic Air Pressure Purge: Releases residual pressure after a fill cycle.
- Air Cooled System: Features dual cooling fans and an automated cool-down cycle to prevent overheating.
- Integrated Output Filter: Helps ensure clean air delivery.
5. Setup
- Placement: Position the compressor on a firm, level surface in an area with good air circulation. Ensure adequate space around the unit for cooling.
- Power Connection: Connect the provided power cord to the compressor's power input socket (refer to Figure 4.3) and then to a standard 110V electrical outlet.
- Hose Connection: Attach the output hose with the female quick disconnect fitting to the compressor's output port. Ensure it is securely fastened.
- Filter Check: Verify that the integrated output filter with bleed valve is correctly installed. This filter helps remove moisture and particulates from the air.
6. Operating Instructions
Follow these steps to operate your Air Venturi EVO-310 Compressor:
- Connect Device: Connect the female quick disconnect fitting of the output hose to the male fill probe of your Pre-Charged Pneumatic (PCP) gun or air tank. Ensure a secure connection.
- Set Desired Pressure: Use the digital display and controls to set the target fill pressure. The unit display can be adjusted between BAR, PSI, and MPa. Do not exceed the maximum safe working pressure of your PCP device.
- Power On: Flip the main power switch (refer to Figure 4.3) to the "ON" position. The compressor will begin to operate.
- Monitor Filling: The compressor will automatically fill the connected device to the preset pressure. The digital display will show the current pressure.
- Automatic Shut-Off: Once the target pressure is reached, the compressor will automatically shut off.
- Automatic Air Pressure Purge: After shut-off, the system will automatically purge residual air pressure from the hose.
- Disconnect Device: Once the pressure has been purged, safely disconnect your PCP gun or air tank from the quick disconnect fitting.
- Cool Down Cycle: The compressor features an automated cool-down cycle during fills. Allow the unit to complete any cooling cycles before storing or prolonged non-use.
Important: Always monitor the filling process and ensure the compressor is not left unattended during operation.
7. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your compressor.
- Filter Maintenance: Regularly check the integrated output filter. The bleed valve should be used to drain any accumulated moisture. Replace filter elements as recommended by the manufacturer.
- Cleaning: Keep the exterior of the compressor clean and free from dust and debris. Ensure cooling vents are unobstructed. Use a dry cloth for cleaning. Do not use solvents or abrasive cleaners.
- Storage: When not in use, store the compressor in a dry, clean environment, protected from extreme temperatures.
- Cooling System: The compressor is air-cooled with dual fans. Ensure these fans are free from obstructions and functioning correctly.
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; Faulty power cord. | Check power cord connection and outlet. Ensure power switch is ON. Try a different outlet. |
| Compressor runs but does not build pressure. | Hose leak; Device not properly connected; Bleed valve open; Internal issue. | Check all connections for leaks. Ensure quick disconnect is fully engaged. Close any open bleed valves. If problem persists, contact support. |
| Compressor overheats and shuts down. | Insufficient ventilation; Prolonged operation; Obstructed cooling fans. | Ensure adequate ventilation. Allow compressor to cool down. Check cooling fans for obstructions. Avoid continuous operation beyond recommended limits. |
| Pressure reading is inaccurate. | Gauge malfunction; Incorrect unit display. | Verify the unit display setting (PSI, BAR, MPa). If discrepancy continues, contact support. |
For issues not listed here, please contact Air Venturi customer support.
