Air Assist Kit installation for Longer Ray5 10W & 5W

Air Assist is an essential upgrade for the LONGER Ray5 10W and Ray5 5W laser engravers, designed to improve engraving quality, reduce burn marks, and enhance cutting performance.

During laser engraving, high-energy beams can generate heat that affects surrounding material, often resulting in charring or uneven edges. An Air Assist system helps solve this by directing a constant stream of compressed air to the engraving area, removing heat, smoke, and debris in real time.

This guide explains how to install the Air Assist kit on both the Ray5 10W and 5W models, including hardware setup and key installation differences.

Why Air Assist Matters

Air Assist improves laser engraving quality by:

• Reducing burn marks and edge charring
• Removing smoke and debris from the cutting area
• Preventing residue buildup on the laser lens
• Improving cutting efficiency and consistency

By cooling the working area with a steady airflow, Air Assist helps maintain cleaner and more precise engraving results without affecting laser power.

Longer Ray5 10W Air Assist installation

The longer Ray5 10W has an official Air Assist kit that consists of two parts, the nozzle kit and the air compressor, available at the following link: https://www.longer.net/products/air-assist-set .

Installing the Longer Air Assist on the 10W laser module is really easy; just follow the steps below:

• First, proceed to disassemble the laser module from the rest of the machine

• Install the metal nozzle on the laser module

• Connect a rubber hose between the metal nozzle and the pressure regulator, and connect another part of the rubber hose to the regulator inlet

• Connect the inlet pipe of the regulator to the outlet of the air compressor

• Finally, install the laser module on the Ray5, activate the compressor switch and start an engraving from the Longer Ray5 display

Longer Ray5 5W Air Assist installation

To proceed with the installation of the Air Assist kit on the Longer Ray5 5W, it is necessary to purchase, as for the 10W version, the kit consisting of the nozzle kit and the air compressor, available at the following link: https://www.longer3d.com/products/air-assist-set . However, the metal nozzle included inside the kit is compatible with 10W module only; therefore, it is necessary to have a 3D printer to print with PLA or PETG the following nozzle: https://www.thingiverse.com/thing:5585296 .

Installing the Longer Air Assist on the 5W laser module is really easy; just follow the same steps as the installing method for the 10W laser module, but install the 3D-printed nozzle on the laser module instead of the metal nozzle. After that, as mentioned, just follow the same steps as shown for installation on the 10W module.

Conclusions

Installing an Air Assist system on the LONGER Ray5 10W and 5W significantly improves engraving quality by reducing burn marks, improving cutting performance, and keeping the laser lens cleaner during operation.

For best results, ensure all air connections are secure, the airflow is stable, and the nozzle is properly aligned with the laser focus point.

Whether for hobby or professional use, Air Assist is a highly recommended upgrade for achieving cleaner, more precise, and more consistent laser engraving results.
