Connecting up to a larger receiver wont increase the CFM of the
compressor, so I wouldnt bother with this until you have tried your
blast equipment, and have determined whether or not you have enough
CFM. You would have a good idea whether or not the set up you have is
likely to work, by the size of the nozzle on your blaster..........if
its anything much above about 6mm diameter, then its only going to work
in short bursts with a 3hp compressor, and you are going to need more
CFM to overcome this problem.
