I'm a little concerned by their choice of the 53 blower. In my opinion, a 47 would be better. I don't know if cranking up the inches mercury to compensate is the answer. There are many similar machines using the same motor and a 47 blower. The old
prochem Apex, the new
570 apex,
titan 575, the new Cleanco slide, etc. These machines all run 400-500 CFM at 13-15 inches hg. The Raptor is aprox 324 CFM at 18-20 hg. I've never tried one so I can't really speak to it's performance. Looks like a well built machine.
