• Variable speed operation Brings the benefits of ECM to high voltage applications without the need of a step-down transformer partnered with a standard voltage ECM Ball bearings

The ECM Blow Motor maintains its high efficiency across a range of operating speeds, which results in a significant reduction in energy use when the motor is run at reduced speeds. This makes these ProTech® blower motors ideal for use in creating two-stage outdoor compressors and heat pump-type units. In addition to reducing electrical use, two-stage compressors feature enhanced humidity removal, less temperature swing between cycles, more even temperatures throughout the home, and quieter equipment operation.
