- Power Off: Ensure your NEJE laser engraving machine is completely powered off and unplugged from the power source.
- Locate M7/M8 Port: Identify the M7 or M8 port on the motherboard of your NEJE laser engraving machine. These ports are typically labeled.
- Connect Relay Module: Connect the included relay module to the M7/M8 port. The relay module enables automatic control of the air pump.
- Connect Air Pump: Connect the air pump to the relay module.
- Attach Air Tube: Securely attach one end of the transparent air tube to the air pump's outlet and the other end to the air nozzle on your laser module. Ensure a snug fit to prevent air leakage.
- Connect Power Adapter: Plug the 12V 2A power adapter into the air pump and then into a suitable power outlet.
- Power On: Reconnect power to your NEJE laser engraving machine. The air assist set will now be ready for automatic operation, adapting to software like Lightburn, LaserGRBL, and NEJE software.
Operating Instructions
The NEJE Automatic Air Assist Set is designed to operate in conjunction with your NEJE laser engraver, providing controlled airflow during engraving and cutting processes. When properly connected to the M7/M8 port, the air assist will activate automatically with your laser operations.
Benefits of Air Assist
Strong and Stable Airflow (48L/min)

The air pump delivers a robust and consistent airflow of 48 liters per minute directly to the laser's focal point. This steady stream of air is crucial for effective material processing and maintaining optimal laser performance.
Cleaner Material Surface

By rapidly reducing the surface temperature of the material, the air assist prevents deformation and discoloration caused by high-temperature laser work. This results in smoother lines, intact patterns, and a cleaner material surface, contributing to a higher quality finished product.
Protection for Laser Module Lens

The steady airflow effectively blows away smoke, dust, and debris generated during laser engraving and cutting. This prevents these particles from rising and contaminating the laser module lens, thereby extending the service life and maintaining the clarity of your laser module.
Low Noise and Vibration Operation

The NEJE air assist pump is engineered for quiet operation with minimal vibration, ensuring a more pleasant working environment without significant noise disturbance.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your air assist set.
- Clean Air Filter: Periodically check and clean the air filter (if applicable) to prevent dust accumulation and maintain efficient airflow.
- Inspect Air Tube: Ensure the transparent air tube is free from kinks, blockages, or damage. Replace if necessary.
- Keep Vents Clear: Ensure the air pump's ventilation openings are clear of obstructions to prevent overheating.
- Store Properly: When not in use for extended periods, store the air assist set in a clean, dry environment.
Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No airflow from nozzle | Air pump not powered, tube kinked/blocked, relay module not connected correctly. | Check power adapter connection. Inspect air tube for obstructions. Verify relay module connection to M7/M8 port. |
| Weak airflow | Air filter clogged, air tube partially blocked, pump malfunction. | Clean or replace air filter. Check air tube for partial blockages. Contact support if pump appears faulty. |
| Air assist does not activate automatically | Relay module not connected to M7/M8, software settings incorrect. | Ensure relay module is correctly plugged into M7/M8. Check your laser control software (Lightburn, LaserGRBL, NEJE software) settings for air assist control. |
| Unusual noise or vibration | Pump not on a stable surface, internal component issue. | Place the pump on a flat, stable surface. Ensure no objects are touching the pump. If noise persists, contact support. |
