Design & Construction
Built to NEMA 56 frame standards, the Marathon S115 ensures straightforward drop-in replacement compatibility with existing equipment. The Open Drip Proof (ODP) enclosure protects internal windings from dripping liquids and falling debris in non-hazardous indoor environments, while still allowing adequate airflow for efficient motor cooling. Precision ball bearings provide smooth, low-friction operation and extended service life, reducing maintenance intervals and downtime.
Resilient Base Mounting
The resilient base mounting system isolates vibration from the driven load and the motor frame, minimizing noise transmission and protecting connected equipment. This makes the S115 an ideal choice for applications where vibration control and quiet operation are priorities, such as air handlers, fan coil units, and HVAC blower assemblies.
Dual-Voltage Flexibility
The 115/230V AC dual-voltage design allows technicians to wire this motor for either standard residential or light commercial power supplies without requiring a separate motor for each application. Simply configure the motor leads to match the available supply voltage for a fast, code-compliant installation.
Applications
- HVAC air handlers and blower assemblies
- Fans and ventilation equipment
- Pumps and hydronic systems
- Light industrial machinery
- Commercial refrigeration fans
