Mestek j31r04093-002 Fan Motor 1/4 Hp 1050 Rpm Odp

Product Description

The MESTEK j31r04093-002 is a 1/4 HP open drip-proof (ODP) fan motor designed for use in unit heater and cabinet heater applications. Rated at 1050 RPM and 115 volts, this motor delivers consistent airflow performance in forced-air heating systems. It is an OEM-style replacement component installed by licensed HVAC technicians during scheduled maintenance or motor failure service calls. The ODP enclosure makes it suitable for semi-protected indoor installations where moisture exposure is limited.

This fan motor is designed for use with Sterling XF125, XF150, and XF300 series unit heaters. These are typically found in commercial and light industrial environments such as warehouses, garages, and manufacturing facilities where forced-air unit heaters provide space heating. The motor drives the fan assembly that moves conditioned air across the heat exchanger and into the space.
