Rectorseal m20729 Condenser Fan Motor 1/3 Hp 208-230V

Product Description

The RECTORSEAL m20729 is a totally enclosed, single-phase outdoor condenser fan motor rated at 1/3 HP and 208-230 volts with a fixed speed of 1075 RPM. It uses a ball bearing design engineered for high-temperature outdoor environments, carrying a 70 degrees C rating under the SunSlinger designation. The motor runs on a 7.5 MFD capacitor at 370 volts and draws 2.4 full-load amps. It is built for continuous duty with Class B insulation and includes an integrated thermal overload protector. Licensed HVAC technicians install this motor as a direct OEM-style replacement in residential and light commercial condensing units.

This motor is designed for outdoor condenser fan applications where heat resistance and reliable bearing life are critical. The NEMA 48 frame accommodates multiple mounting configurations including thru-bolt, band mounting, Rheem bolt pattern with pre-installed screws, and Trane 4.33-inch bolt circle holes with self-tapping screws. A water slinger on the shaft helps protect against moisture ingestion during outdoor operation. The capacitor requirement is noted directly on the motor label, simplifying replacement verification in the field.

Key Features

• Totally enclosed construction rated for outdoor condenser fan duty
• High-temperature 70 degrees C SunSlinger rating for demanding ambient conditions
• Ball bearing design for extended service life under continuous duty cycles
• Pre-installed Rheem mounting screws and Trane 4.33-inch bolt circle self-tapping screws included
• Water slinger on shaft for moisture protection
• Thermal overload protection with Class B insulation
• Capacitor requirement labeled directly on motor for easy field verification

Compatibility

Designed as an OEM-style replacement condenser fan motor with mounting provisions for Rheem and Trane bolt patterns; verify shaft diameter, rotation direction, capacitor rating, and voltage before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit before removing the existing motor. Confirm rotation direction is REV (counterclockwise when viewed from the shaft end) and match the 7.5 MFD capacitor rating before energizing. Verify that the selected mounting configuration aligns with the unit manufacturer bracket before securing hardware.
