Fan Rotor Balancing
I have been using the VIBXPERT® II Balancer for a year. I have balanced fans ranging in size from 10, 000 to 1 HP, mostly within 3 shots. My last customer had a contractor quoting a fan rotor replacement. Using the VIBXPERT II, the fan was balanced to 2 mils from 25 mils in 3 shots. The customer cancelled the fan replacement. The ability to acquire and view spectrum, review cost down data, and perform resonance testing are features not found in other balancers.  —Victor Galanto, Fan Services Associates
