Fume Extractor for Laser
I was hesitant to post this, but it seems to work relatively well. I like the creativity of both Tom C and DrSys’s approach to fume removal. Call mine the Jerry-rigged version involving sewer pipe, a heat gun, rubber mallet, and 1” spacer board.

64W J Tech Laser with air supply from a compressor w/Filter regulator, water separator
Lucky to have a double-hung window close behind the CNC
The 64W is a 3.25” boxy laser and the challenge was to find or make something big enough to surround it. A spider farmer 4” is used to draw fumes (see Tom’s recommendation). With my air compressor in the adjoining attached garage, the air blowing through the laser is from outside the heated workshop; compressed air (being well above freezing) is being sucked out with the fumes. Thus, in theory, I’m keeping my heated shop air….or so I like to think?
The suction pipe is held in place using a bolt and the spindle collet. The spindle/router may have to be adjusted up or down within the clamp for the just-right setting. Hope photos will clarify everything.
Caution! Is easy to raise Z and ram the pipe into the Z slider frame.
HIGHLY RECOMMED Using a “no Z” post processor”
If someone can design something for the 64W Laser, I’ll be the first in line!
Thanks Bill
