What actual poundage do you need, and I have never heard that an air wrench will double as a torque wrench. That is 30 lbs of pressure, not 30 lbs of torque. What if the air wrench has torque multiplation in it ?
Spend the money on a torque wrench. You will use it again.

You can probably rent a torque wrench if you need it or buy a torque multiplier or use a crows foot if it's close. Torque = force x distance so if you apply 30lb feet a few inches away you can solve for your applied torque. Say the head is 2 inches away from the fastener now 30 lbs x 1ft + 2 inches is actually 35 lb-ft when it clicks on the crows foot vs 30 say. Depending on space it may be a valid option if you have one laying around.

OP you need to do some reading regarding impact tools, compressors, the difference between ft-lbs and in-lbs.
FYI, if you set the compressor to 30 psi the impact tool would not work at all.

You should be able to pick one up at that Pl;ace that advertises everywhere ( don't know if mentioning the name is allowed) for about $10. Not the best quality but they do work. Look for a Coupon. A 3/8 version will work well for 30 lbs measurement.

I bought one at Harbor Freight as my Craftsman broke during a head swap. I compared it to a freinds Snap On and it was just as accurate. For how long who knows lol.
IT was the click type not the one with that funky beam

As we have come to notice the HF tools have a value to the occasional grassroots mech. 30 ft/lbs is nice and tight.
So rather than fret over exacting values, Pull hard on a 12" wrench and you'll be fine.

Get one of these:
Not only will it measure torque accurately using only a ratchet/flex handle, but it can be used to calibrate an extisting torque wrench.
I have three torque wrenches of overlapping capacities, but since getting this device I seldom use the torque wrenches if I only have one or two fasteners to torque ....just use this and a flex handle. No adjusting a torque wrench and then backing it off again.
