I purchased a used sata nr2000 a few months back for my project but, after reading some threads about how this gun is an air hog I checked the specs on my compressor. It is a 7 hp 60 gallon tank unit that produces 11.8 cfm at 40 psi but, apparently this isn't enough. So, will this work for me or should I look for another gun? I just bought the compressor last year so I don't want to replace it. Thanks.
