Homemade fume extractor

[advmaker]

Just testing out a cheap way to suck fumes. Seems to work with a $15 fan.

Flammable fumes? Fans aren't electrically protected so explosion risk if you're sucking flammable fumes.

Shaded pole motors, like small fans, are inherently explosion-proof, since there is no spark like there is with a centrifugal switch on a larger induction motor.
