Exhaust Fan/Fume Extractor; Setting Up An Exhaust Fan - BOSSLASER LS Series Operator's Manual

Exhaust Fan/Fume Extractor

The laser vaporizes material as it moves along the axis, this generates large amounts of smoke. The exhaust of your
machine and its importance cannot be overstated as it is necessary to remove harmful fumes and smoke produced by
the laser machine. Some materials such as leather or wood generate larger amounts of smoke than other materials.
If you did not purchase a fume extractor, the exhaust must be ducted to the outside and away from any area where
animals or humans congregate. When ducted correctly, a laser can be placed in an office, garage, or spare room.
If you will be cutting or engraving materials that will produce large amounts of smoke or fumes, industrial size in-line fans
can be purchased from websites like Grainger and other industrial supply warehouses. All Series LS machines will need a
6" exhaust fan with a minimum of 500 CFM's.
Additionally, be certain to have the on/off switch within reach of the laser panel for easy access at all times. The exhaust
fan must be turned on and used each time the laser is running and in use.

Setting Up an Exhaust Fan

Figure 2a. Exhaust system configuration with an exhaust blower.
First, ensure your machine is placed in an appropriate area that has an option for venting, this can include a door, window,
duct, etc. You will need to exhaust your machine outside if you are using an exhaust fan.
Remove the exhaust blower box and exhaust tubing from the crate, as well as your exhaust hose clamps from the toolbox.
You will take one (1) exhaust tubing from the crate and place it on the exhaust port, located on the back side of the
machine on the bottom (this will be a 6" metal circle). Once the tubing is placed on the exhaust port, take one (1) exhaust
hose clamp, and place it over the tubing and the exhaust port. Now that the exhaust hose clamp is properly placed,
tighten it down so there is a snug fit with minimal room for fumes to escape.
After the first end of the exhaust hose has been placed and secured, take the second exhaust hose clamp, and place it on
the other end of the exhaust tubing. Next, place the exhaust tubing and clamp on the intake port of the exhaust fan, as
shown above, after it is correctly positioned tighten down the exhaust clamp as you did the first time.
Finally, take your second piece of exhaust tubing and third exhaust hose clamp and attach them to the exhaust out port
of the exhaust fan, tighten down the exhaust clamp as you did the previous clamps.
Now that you exhaust fan has been properly set-up. Take the other end of your exhaust tubing and place it where you
will be able to exhaust smoke and fumes. If you are going to be exhausting your machine through a duct or other
fabricated output, you may need another exhaust hose clamp to ensure that it stays secure.
