The XL300 fume extractor comes with a built-in airflow alarm to alert users when insufficient air is being drawn from the machine - If something unnoticed goes wrong with the system, this is a safety feature to prevent subtle or undetected fumes from escaping the laser in high concentrations.
The most common causes of the low-airflow alarm are:
1. Clogged filters or prefilter.
If you open the front of the filter box using the chrome latches on the right side, you can visually check the filters for blockage.
If a filter is clogged, you can try knocking the debris out into a garbage can while outdoors or in a well-ventilated area to extend the lifetime of the filter.
Remove the hose from the extractor's "in" port and ensure no debris has collected in the hose or prefilter before reattaching.
Always wear appropriate PPE when removing or shaking out filters, as fine particles can be hazardous.
2. Laser's exhaust fan.
The laser has a built-in booster fan to help the filter system remove smoke more quickly - it is toggled using the small chrome button beneath the laser's power switch and e-stop.
If the filters are clean but the alarm persists, check to ensure the laser's exhaust fan has not been disabled.
