I’ve used the usual free-standing table top fume extractors, but they’re noisy and always seem to be in the way.

So, when I was reconfiguring my bench, I built the extractor into it.

It consists of a cheap $10, bathroom vent fan with a couple of PVC connections from the intake that run through the front of the bench.  From the exhaust side, a long pvc pipe runs along the back of the bench, and blows it against the floor 6 feet away.  Sorry, no pictures of the steup on the back of the bench… although it is on wheels, the fully loaded bench weighs a few hundred pounds, so I don’t move it often.

The intake is Loc-Line anti-static vacuum tubing, from loc-line.com  This is a series of 2.5 inch diameter, hard plastic segments that interlock to make a flexible tube, and capped with a rectangular nozzle.  Part numbers:  81302AS, 81304AS.

Nothing fancy, there’s no trim ring around the intake.  The switch on the left of the intake controls the fan.

The flex-tubing is connected to a PVC elbow, that elbow is just press-fit into the intake.  This has worked well, it is easy to remove and to adjust.
