Today we installed a new blower on one of our Rodgers/Carlson hybrid organs. The original blower died in February, and today we installed the new one. In addition, we also relocated the blower into the adjoining mechanical room onto the wall, rather than the uninsulated tower room behind the organ pipes. The tuning varied during the winter and summer months because the extreme temperatures in the tower were affecting the pipes during playing. Controlled by a Variable Frequency Drive (VFD), the blower is now running on its proper 240v 3-phase circuit, instead of a “phantom third-leg” capacitor. The VFD also allows us to slowly ramp up the motor speed slowly instead of shocking the motor with full-power when first turned on, and also allows us to monitor the hours the motor runs and to indicate when it needs oiling. Plus, this unit is incredibly quiet, you don’t even know it turned on.
