Rectorseal M10690 Direct Drive Blower Motor 3/4 Hp

Product Description

The RECTORSEAL M10690 is a direct drive blower motor rated at 3/4 horsepower and 230 volts, designed for continuous-duty air handling applications in residential and light commercial HVAC systems. This single-phase PSC (permanent split capacitor) motor runs at 1075 RPM with a 6-pole configuration and offers three speed selections, giving installers flexibility when matching airflow to system requirements. The open air over (OAO) enclosure allows airflow across the motor for cooling, and the automatic thermal protection guards against overheating during sustained operation. Sleeve bearings and a 1.0 service factor round out the core mechanical profile.

The M10690 is suited for direct drive blower applications inside air handlers, furnaces, and fan coil units where a 230-volt single-phase PSC motor is specified. The reverse (REV) rotation and variable speed range of 925 to 1200 RPM make it adaptable to a range of blower wheel configurations. Licensed HVAC technicians typically install this motor as a replacement in existing equipment or as a specified component in new installations where continuous-duty, multi-speed operation is required.

• Sleeve bearings support quiet, low-maintenance operation in horizontal or vertical mount positions

Compatibility

Designed as an OEM-style replacement direct drive blower motor for residential and light commercial air handlers, furnaces, and fan coil units requiring a 230-volt single-phase PSC motor at 3/4 HP.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local codes and manufacturer guidelines. Disconnect and lock out all electrical power to the unit before removing the existing motor or making any wiring connections. Confirm shaft diameter, mounting configuration, and rotation direction match the blower assembly before securing the motor. Do not energize the motor until all wiring, mounting hardware, and blower wheel set screws are fully secured.
