The Fasco D1100 is a direct replacement condenser fan motor engineered for Loren Cook ventilation equipment. Running on standard 115V/60 Hz power, this shaded-pole motor delivers two selectable speeds -- 1550 RPM high and 900 RPM low -- making it a reliable drop-in for systems that require variable airflow. Thermally protected and built to a 3.3" frame diameter, it installs on extended shaft-end studs and ships ready to connect via quick-connect terminal housing.
When your Loren Cook condenser fan motor fails, getting the wrong replacement means re-wiring, re-mounting, or returning parts. The D1100 matches the original electrical and mechanical configuration so you spend time installing, not adapting. The 12" lead wires reach typical junction points without splicing, and the quick-connect terminal housing speeds up reconnection.
Also cataloged as NBK Parts number 20225, this motor is stocked by HVAC/R distributors and specialty suppliers and is a well-documented cross-reference for Loren Cook OEM part numbers.
Selectable 1550 RPM (high) and 900 RPM (low) via separate leads. Match the speed to your system's airflow requirement without adding a speed controller.
Internal thermal overload protector shuts the motor down if it overheats, protecting the winding and reducing fire risk in enclosed equipment cabinets.
Carries both CSA listing and UL recognition, meeting the safety certification requirements expected by commercial and residential HVAC/R equipment inspectors.
Pre-installed quick-connect housing on 12" leads -- no stripping or crimping required on the motor end. Speeds up both initial installation and future serviceability.
The D1100 uses a shaded-pole design, the correct topology for low-horsepower condenser fan duties where simplicity and long service life matter more than efficiency. The 4/6-pole configuration corresponds to the two speeds (1550 RPM at 4-pole, 900 RPM at 6-pole on 60 Hz power). Class B insulation (rated to 130 deg C winding temperature) provides a solid margin above the 40 deg C (104 deg F) ambient temperature rating.
Sleeve bearings are used rather than ball bearings -- appropriate for the low-load, low-vibration duty of a condenser fan, and quieter in operation. The open air-over enclosure relies on the airstream passing over the motor for cooling, which is standard for fan-duty motors mounted in the airflow path.
The shaft extends 2.45" from the face of the motor, giving adequate engagement depth for typical fan blade hubs. Rotation is clockwise when viewed from the shaft end -- confirm this matches your existing fan blade pitch before installing. Reversing a clockwise motor with a blade designed for counterclockwise rotation will move air in the wrong direction and reduce cooling performance significantly.
Current draw is 1.20 amps on high speed and 0.70 amps on low speed at 115V. Total connected load is well within standard 15A branch circuit capacity. The quick-connect housing accepts standard female spade terminals. Lead length of 12" is sufficient for most Loren Cook cabinet wiring without extension, but verify your routing before cutting leads shorter.
