Belzonaの事実
The Belzona rebuild is more cost effective than replacing the AR wear plates. Also, power drawn by the fan motor is dramatically reduced. For these reasons, this has become a regular maintenance procedure on this fan. In this case, the fan rotor had been neglected for several years as it was scheduled for replacement. Unfortunately, the new rotor was not effective so the original one was reinstalled and rebuilt once again with Belzona.
