The trick is to use a nozzle sized for the CFM available and in this case a 1/8" should be about right, you could use a 5/32" but it would require some waiting because of exceeding the compressor output but still not too bad to use.
And yes that Bellaire is a brute also! Darn good compressors for the money.
That is a sweet Compressor.. My friend speedydeedy has one he bought about 18 years ago and never gave him any problems yet..
And it will fill that tank very fast... If your running a DA sander, It will stop pumping air while your still useing it..And it will wait for you to catch up... I like that...
