A fume extractor for a laser engraver is a crucial device that ensures safety and maintains air quality during laser cutting or engraving processes. This article introduces how it works and why you might still experience strong smells even after installing one.
1. How does a fume extractor work?
Contaminated Air Intake: The fume extractor pulls in the smoke and particles that are generated during the process of engraving and cutting.
Filtering Process:
- The first filter captures airborne particles, including dust and fumes.
- The second filter of HEPA grade further removes fine particles.
- The third filter absorbs specific chemicals.
Clean Air Release: After filtration, the extractor releases clean air back into the room.
2. Why Might You Still Smell Odors?
For the laser engraver:
1) Check the air assist set
Please check whether you can feel the vibration of the air assist set when you are engraving or cutting a project. Also, is there anything that might block the little hole in the air assist?
Note: the small hole is located in the middle of the lightening bolt.
Please check whether you have turned on the "air assist switch" (settings>air assist switch)
2) Check the fan inside and at the back of the machine:
- Is it spinning and working properly during the process of engraving and cutting?
- To ensure the proper performance of the laser engraver, we also recommend regularly cleaning the fan every 1- 2 months.
For the Fume Extractor:
1) Installation and Setup
- Connecting the hose from the laser engraver to the fume extractor.
- It is not recommended to use an extension pipe, as the longer the pipe, the worse the smoke exhaust effect will be.
- Switch on the fume extractor, and set the parameters to 100.
2) Test the Suction of the Fume Extractor
- Power on the fume extractor, disconnect the hose, please put your hand on the center of the interface, can you feel the suction of the machine?
- Please note: there are 3 filters in total inside the fume extractor, each of which, if clogged, could potentially prevent smoke from being effectively expelled. You may start by removing each filter one by one. As you do so, pay attention to the suction. This will help you identify if there is any blockage or restriction in the flow of air for each filter.
- Instead of using a fume extractor, try to vent it out of the window. This will help us determine if the issue lies in the laser engraver or the purifier itself. Observe the smoke exhaust performance in the meantime.
Always remember that while a fume extractor significantly reduces odors and protects your health, it’s essential to address other factors like materials choices and proper maintenance to minimize smells in your workspace.
