High Efficiency Blower Fan Motors and WCCs

Reduce repair costs and with early retirement of your old standard efficiency PSC blower fan motors before they fail with new high efficiency BPM motors.

Standard efficiency PSC motors really on capacitors, one of the most common parts in an HVAC system to fail. High efficiency BPM motors are more reliable because they do not use capacitors. Note: the compressor and condenser fan motors will continue to rely on capacitors.
