Impeller RPM or RPM+Boost, death of the Blower?
Is impeller speed of 42,000 rpm at 8psi, the same as 42,000rpm at 4psi? Does the slipping or friction of the ball drive on the output depend more on the boost (measure of resistance) or is the impeller speed the culprit of potential damage? I realize that the impeller has a maximum efficiency point rpm wise, but I was wondering what really is the cause of damage for SN units. Is it the rpm? Or the RPM + boost? I have read a lot of threads that say don’t over spin the blower. I was just curious if anybody has an opinion on the matter. Thanks
