How to Install and Use a Fume Extractor for Laser Engraver

When working with a laser engraver, smoke and fumes are an unavoidable part of the process. These by-products, if not properly managed, can affect the quality of your work, damage your equipment, and most importantly, pose health risks. A fume extractor is an essential accessory that keeps your workspace clean, safe, and pleasant to work in. Whether you’re a hobbyist or running a small business, understanding how to correctly install and use a fume extractor is crucial for both safety and efficiency.

How to Install a Fume Extractor for Laser Engraver

In this guide, we will use the OMTech's Fume Extractor for Laser Engraver as an example. Please note that the installation and operation process may vary slightly for different models, so always refer to the specific user manual for your machine.

1. Attach the extraction hood to the large end of the extraction tube.

2. For LSP-0180, insert the small end of the extraction tube into the air inlet located on the top cover of the main machine.
For LSP-0250, if you want to use only one of the extraction tubes, cover the other air inlet with the wind shield.

3. (Optional) If you want to use the aluminum tube, install the tube adapter:
a. Remove the top cover by opening the cover latch.

b. Remove the screws using an M3 hex screwdriver (not included).

c. Align the holes on the adapter with those on the main machine.
d. Insert the screws into the holes.
e. Fit the nuts onto the screws, tightening them in place..
f. Replace the top cover.

4. Adjust the extraction tube and hood according to your needs.

Note: The longer and curvier the extraction tube, the weaker the suction will be at all levels. For best results, position the source of the fume 10–15 cm (4–6 in.) away from the extraction hood.

5. After ensuring your power supply is compatible and stable, connect the power cord to the main machine and then its power supply. Check that all power connections are stable.
