Fasco D143 Motor
The Fasco D143 Motor is an industry-standard shaded pole ventilator motor designed for high-performance air-over applications, including unit heaters, rooftop ventilators, and exhaust systems. Built with a 5-inch diameter 42 frame, this versatile unit delivers a dual-rated output of 1/30-1/40 HP, allowing technicians to match specific torque requirements for Siegler, Williams, or Sears wall furnaces. Operating on 115V single-phase power, the motor offers 2-speed flexibility (1050 RPM) to optimize airflow while maintaining energy efficiency in open air over (OAO) environments.
Engineering features include sleeve bearings for quiet operation and a 1/2" diameter x 1-5/8" length shaft with a flat for secure blower wheel attachment. For simplified field installation, the Fasco D143 utilizes extended studs on the lead end and 10-inch leads with quick-connect terminals. The assembly is thermally protected with an automatic reset to prevent coil burnout under heavy static pressure. This direct drive blower motor is a reliable 1050 RPM replacement that ensures consistent counterclockwise shaft end (CCWSE) rotation in critical heating and ventilation equipment.
Key Benefits- Universal Compatibility: Direct replacement for several Williams/Sears furnace and Penn ventilator models, reducing downtime on the job site.
- Dual Speed Versatility: High/Low speed settings (1.5/1.0 Amps) allow for precise air volume control in varied seasonal conditions.
- Rugged Construction: Features a resilient 42-frame design with Class A insulation, rated for 40°C ambient temperatures.
- Safety Integrated: Automatic thermal overload protection guards the 115V windings against overheating and electrical stress.
- Serviceable Design: Includes extended mounting studs and 1/2-inch flat shaft for fast, drop-in replacement in existing brackets.
What is the correct rotation for the D143 motor?
This motor is designed with counterclockwise rotation when viewed from the shaft end (CCWSE). Always verify the blower wheel pitch before installation to ensure proper directional airflow.
Can this motor be used in totally enclosed applications?
No, the Fasco D143 has an Open Air Over (OAO) enclosure. It requires the airflow from the fan blade or blower wheel it is driving to maintain proper internal operating temperatures.
Which wall furnaces are compatible with this unit?
The D143 is a standard cross-reference for Williams, Sears, and Siegler wall heaters. It effectively replaces various OEM parts from McMillan (A0510B2105) and Century (DA3D180).
