Thanks for all the input guys. After reading all the comments I think the
sensible option is to see how I get on with just the one compressor.

Thanks again

Its really down to the type of blasting you want to do. If you have a
small blast cabinet, and dont want to use it continously then a 3hp
compressor will work fine. On the other hand if you need to do anything
much more than that, you really do need more air.
