General Purpose HVAC

ABB's Baldor-Reliance® General Purpose HVAC motors are specifically engineered with industry-driven designs to keep air handling systems running smoothly, quietly and efficiently, which means better system reliability and performance with less maintenance. Rotors are dynamically balanced to reduce noise and increase bearing life, and each motor includes a bar code spec number for easy identification. Mounting holes on drive endplate enables field conversion to add a shaft grounding ring if desired.

ABB's Baldor-Reliance General Purpose HVAC motors perform in the harshest applications while lowering total cost of ownership.
