effectively reducing winding heat and improving torque during the start-up cycle

While a 440V capacitor can replace a 370V capacitor (as voltage is a "not-to-exceed" rating)

This robust condenser fan blade is the direct successor to several obsolete part numbers

maintaining a footprint compatible with most HVAC mechanical linkages
