I wonder if it would be worth it to use a venturri at the nozzle to
increase air volume.

Yes, and if you can tap the compressor tank BEFORE the regulator, it
certainly
will be more efficient. The high airspeed from full pressure air is not
required, but throttling the pressure is a waste of energy/compressor
power. It'll be a trifle noisy, though; consider earplugs.

Lots of airguns use venturis (venturae?) anyhow, you might just find
a suitable
nozzle off-the-shelf.


Actually I have a venturi vacuum pump I was thinking about repurposing.

However routing a new line all the way around the shop and thru the
machine room is not a quick short term answer as discussed in other posts.
