What Is an OPAO Motor?
An Open Protected Air Over (OPAO) motor is specifically designed to be mounted directly in the airstream of a fan or blower. Rather than relying on its own internal cooling fan, the motor is cooled by the air flowing over it from the driven equipment. This design makes OPAO motors compact, lightweight, and ideal for evaporator coil fans, refrigeration unit fans, and similar HVAC applications.
Applications
- Evaporator fan motors in refrigeration and HVAC systems
- Condenser unit fan drives
