I bought it for the large volume (it is a 33 cu. ft. compressor) and I set the line pressure at 80psi when blowing out the system. Have blown it out about 5-6 times plus the neighbors with no ill effects yet. The compressor is fine, it's just the "free" air tools that are pathetic. I guess you get what you pay for
As it is an "oil-free" compressor I am more worried about losing my hearing then blowing anything up
