Here's a redneck solution: Looks like it would work though.

Those "Air in a can" dusters use compressed freon I think. Not certain, but they have a long lived air supply. Simply pushing air back into an empty spray can will only give you a minute or so of useable air pressure. Still - if you have a bunch of those duster cans around you can refill them and keep them around for when you need a puff of air.

Used propane tanks are free.

A regular 20lbs like this?

Like that but much much older. The one I have the guard ring around the valve is really close to the valve. And I know how to use a pipe wrench and what direction it goes. Have them from a small 8" to a big 48" aluminum Ridgid one. And many 14" ones that get the most use.

Wouldn't that be eligible for a Darwin Award wen you connect it to a tank full of propane to blow out dust of your drill?
How? It was empty when I started, and I filled and emptied it with air until the mercaptan smell was gone

Even used propane tanks aren't cheap. Found a 5-gal 125-psi air tank @ Tractor Supply for \$33 but it would still need some correct hose and fittings.
Mine was a leftover from back in my Jeep hill climbing days in the 70's. It was on my camper trailer. Harbor Freight sells one too, comes with the hose and fittings.

Most I think have 15lb in a 20lb tank.
Yep they need to leave room for the liquid to out gas to go into the grill or what ever.

Here they are stamped and dated, pressure tested also
The new ones are, but they don't get recertified like a welding gas tank has to. The propane tanks have a 250PSI working pressure

It has a 4' hose and air chuck but will need to put in a quick disconnect for the blowoff and my gauge chuck.
