The Century Motors 429 is a multi-horsepower shaded pole HVAC motor engineered for direct drive blower applications and fan coil units. Operating at 1050 RPM with three distinct speed taps, this motor provides 1/5-1/6-1/8 HP versatile output, making it an essential stock item for service technicians. It features a 42Y Nema frame size with an open air-over (OAO) enclosure to ensure optimal heat dissipation during continuous operation. The unit is designed for 208-230V single-phase power systems, drawing 3.4-2.7-2.2 Amps depending on the selected speed. This direct replacement for S1-3118C312P utilizes a 1/2" x 3 3/4" shaft and reliable sleeve bearings for quiet, vertical or horizontal mounting. With a CCW lead end rotation, this motor is built to restore factory airflow specifications in residential and light commercial air handlers while maintaining peak electrical efficiency on the job site.
