I don't buy long air blow guns. I just remove the tip and put in a fitting w/a piece of copper tubing on it. I have one w/a piece of 1/4" tubing about 8-9 inches long that I can leave straight or bend into whatever shape is needed to get into or around corners, need to replace that tube every few years due to it being bent too many times. Also have a fitting w/a 3/8" tube about 3' long for the hard to reach places or just wanna stay away from the dust that's going to be kicked up.
I also have the drain on the tank relocated w/a ball valve for quick easy draining, drain it lots except in the winter when the water in the bottom of the tank is frozen. Did that once and boogered up the valve.
