It includes a capacitor (7.5μF/370V) and is compatible with numerous D1101, D1127, and related models, including Century and GE replacements. Its reverse-compatibility and dual-voltage support make it a flexible option for refrigeration and bathroom exhaust fans in mixed-duty environments.
Packard 1/20 HP 1550 RPM 3.3″ Motor 40132
The Packard 40132 is a shaded pole, open-enclosure motor designed for single-phase ventilation needs. It operates at 115V, 1550 RPM, and 3.3″ frame diameter. Rotation is determined by viewing the shaft end, and the design anticipates straightforward replacement in compatible blowers and fans within HVAC assemblies, keeping systems running smoothly.
Fasco D132 3.3″ Frame Open Ventilated Motor
The Fasco D132 motor is an open ventilated shaded pole general purpose unit with sleeve bearings and thermally protected operation. It provides CW shaft-end rotation and 115V, 60Hz power. Designed for durability in continuous-use environments, this model offers reliable performance with straightforward mounting for common D132 applications.
1/20 HP 1045 RPM Direct Interchange
This model offers 1/20 HP at 1045 RPM with 115V operation. It is designed as a direct interchange to FASCO D1037 (Penn Vent 7151-2139), making it a convenient swap for legacy blower installations. It features a compact 5″ diameter and a bolt-pattern suitable for typical mounting arrangements in older HVAC units and fans requiring a compact, compatible replacement.
Fasco D133 3.3-Inch General Purpose Motor
The Fasco D133 motor is a 1/20 HP, 115V unit rated at 1500 RPM with sleeve bearings and a single-speed design. It is intended for OAO enclosures and is suitable for a range of general-purpose blower and fan applications where a compact, reliable motor is needed. CCW rotation specifics should be confirmed for each installation.
Buying Guide: Key Purchase Considerations
- Frame compatibility: Ensure the motor frame matches your blower or fan housing (commonly 3.3″ for D132/D133 style units).
- Rotation direction: Check if CW or CCW rotation is required by your equipment; most D132-style motors offer specific shaft-end rotation.
- Voltage and frequency: Most 1/20 HP HVAC motors run on 115V, 60Hz. Some models support 230V variants—verify your power supply.
- Bearings and lubrication: Sleeve bearings are typical for budget motors, while ball bearings offer longer life under high starting loads or vibration.
- Thermal protection: Thermally protected windings reduce overheating risk in continuous operation.
- Overload protection and enclosure: Open vs. OAO (open ventilated) enclosures suit different installation environments and safety requirements.
- Material quality: Copper windings often provide better heat dissipation and durability than aluminum windings.
- Replacement compatibility: If replacing an older model, verify cross-reference numbers to ensure a direct or easy interchange.
- Noise and efficiency: Low-noise designs and efficient operation are beneficial for residential settings and quiet workspaces.
When selecting, consider the operating environment (residential vs. commercial), required rotation, and whether a capacitor is included or needed for refrigeration or blower applications. Always confirm the exact shaft diameter, mounting pattern, and overall dimensions to ensure a proper fit with your existing equipment.
