How to Maintain a Fume Extractor for Your Laser Engraver
When you’re running a laser engraver—whether it’s for a hobby setup, a growing home business, or a classroom environment—clean air management is essential. A fume extractor helps remove smoke, particulates, and chemical vapours produced during engraving or cutting. Keeping it well-maintained not only protects your health but also ensures consistent engraving performance. To help you keep your workspace safe and compliant, here’s a practical guide of how to maintain the fume extractor for your laser engraver.
How to Tell When Your Fume Extractor Needs Attention
Even a high-quality extractor will show signs of wear over time. If you notice any of the following, it’s a good indication that your system needs maintenance:
-
Airflow feels weaker or inconsistent.
-
Smoke lingers inside the laser bed instead of being cleared quickly.
-
Strong smells—especially from acrylic, leather, or treated wood—persist.
-
The unit sounds louder than normal or vibrates unusually.
-
Filters appear heavily coated with dust or discoloured.
Addressing these issues early helps prevent bigger problems down the track.
General Maintenance
Different fume extractor models have different service intervals, so it’s worth following the schedule provided in your user manual. For example, maintenance for the OMTech 60W Fume Extractor often includes tasks such as:
- Replace the filter elements every 7–15 days.
- Always turn off and unplug the machine before cleaning or maintenance. For best results, turn off and unplug the machine between uses.
- Clean the machine’s exterior, tube or pipe as needed, using a soft cloth. Never allow water to make contact with electronic components. Never use caustic solvents or harsh abrasives.
- Check the filter elements if you notice the machine’s suction is becoming weak. Do not attempt to continue use with clogged filters.
- Mark the specific replacement date on new filters during replacement
How to Replace the Filters Correctly
Note: ALWAYS use appropriate PPE, including an N100 respirator, goggles, and
nitrile or latex gloves before replacing the filter. Disconnect the machine from power before replacement for safety.
1. Remove the two M4 screws on the top cover by hand turning.
2. Take off the top cover.
3. Lift the inner body by its tape strings on each side to expose the cotton filter.
4. Carefully replace the cotton filter with the provided new filter.
5. Reinstall the inner body and top cover.
