Mestek j31r04091 Fan Motor Propeller Odp Gg Series

Product Description

The MESTEK j31r04091 is an open drip-proof (ODP) propeller fan motor designed as a direct replacement for GG Series 60-75 unit heaters and similar forced-air heating equipment. ODP enclosures allow airflow through the motor housing, making this configuration well suited for indoor commercial and industrial environments where the motor is protected from direct water contact. Licensed HVAC and mechanical contractors typically source this motor when a failed or degraded fan motor requires like-for-like replacement to restore proper airflow across the heat exchanger.

This motor is specified for use in MESTEK GG Series 60-75 unit heaters, a line of gas-fired propeller unit heaters commonly found in warehouses, garages, workshops, and light industrial spaces. The propeller-drive design moves large volumes of air at relatively low static pressure, which is the standard configuration for suspended unit heaters in open-bay commercial applications. Installation is performed by qualified HVAC technicians familiar with unit heater service procedures.

Key Features

• Open drip-proof (ODP) enclosure rated for protected indoor environments
• Propeller fan motor configuration matched to GG Series unit heater airflow requirements
• Direct OEM-style replacement minimizes downtime on GG Series 60-75 equipment
• Designed for forced-air unit heater applications in commercial and industrial settings

Compatibility

Designed for use with MESTEK GG Series 60-75 unit heaters as a direct propeller fan motor replacement.

Installation Notes

Installation should be performed by a licensed HVAC or mechanical technician. Shut off all electrical power to the unit heater at the disconnect and verify the circuit is de-energized before removing the existing motor. Close the gas supply and allow the heat exchanger to cool completely before beginning service. Reinstall all guards and enclosure panels before returning the unit to operation, and verify proper motor rotation direction before applying full load.
