Fasco D921 Motor
The Fasco D921 motor is a high-performance direct replacement condenser fan motor engineered for demanding commercial rooftop and residential outdoor units. Operating at 460V (or 230V) and 825 RPM, this 1/3 HP motor features a Permanent Split Capacitor (PSC) design that ensures peak electrical efficiency during continuous duty cycles. Built with a NEMA 48 frame and a 5.6-inch diameter, it utilizes all-angle ball bearings, allowing for versatile shaft-up, shaft-down, or horizontal mounting configurations. The motor is electrically reversible, featuring a 1/2" x 6-3/8" shaft with double flats for secure fan blade attachment. With an open air over (OAO) enclosure and Class B insulation rated for 60°C ambient temperatures, the Fasco D921 is designed to withstand the harsh thermal conditions of HVACR environments while protecting against internal overheating via automatic reset thermal overload protection.
- Universal Voltage Flexibility: Supports both 230V and 460V single-phase power supplies for broader field compatibility.
- Superior Bearing Life: Equipped with heavy-duty ball bearings to handle high thrust loads and provide long-term reliability in any orientation.
- Reversible Rotation: Simple lead switching allows for either CW or CCW rotation, reducing the need for multiple van stock items.
- Extended Shaft Design: The 6.42-inch shaft length with double flats provides maximum adjustment for various fan blade depths.
Common Questions
What size capacitor does the Fasco D921 require?
This motor requires a 5 MFD 370V run capacitor for proper startup and operation.
Can this motor be used in heat pump applications?
Yes, its all-angle mounting and thermal protection make it suitable for both straight-cool condensers and heat pump systems.
Is this a direct replacement for 1075 RPM motors?
No, this is an 8-pole motor designed specifically for 825 RPM applications. Always match the RPM and HP of the original motor to maintain system airflow and static pressure.
