Just got a '72 loadstar 1700 and was wondering if anyone might know the cfm output of the air brake compressor. I've got some sandblasting to do and the electric compressor I have is pretty small.
Ok looks like this rig uses a bendix 550 pump which puts out almost 10 cfm at 120 psi running at 2000 rpm. This is big enough to run the sandblaster continuously. and no more while sandblasting.
and no more 
while sandblasting.
