Fasco D150 Blower Motor

The Fasco D150 Blower Motor is a high-performance 1/4 HP replacement motor designed for demanding HVAC delivery systems. Operating at 115V with a 3-speed configuration, this PSC motor features a 5-inch diameter NEMA 42 frame and a resilient/thru-bolt mounting system for broad compatibility. Engineered with sleeve bearings and Class B insulation, it maintains a consistent 1050 RPM and handles ambient temperatures up to 40°C. The open air over (OAO) enclosure ensures maximum heat dissipation, while the reversible rotation provides versatility for various fan configurations. With a 4.7 full-load amp rating and thermal overload protection, this motor provides reliable service in air handlers and furnace units. For optimal performance, pair this unit with the G21-930 capacitor. The 1/2" diameter shaft extends 6 inches, allowing for precise wheel alignment in restricted cabinets.

Common Questions

What capacitor is required for the Fasco D150?
This motor requires a 5 MFD 370V capacitor (model G21-930) to ensure the permanent split capacitor (PSC) circuit functions efficiently.

Can the rotation of this motor be changed in the field?
Yes, the Fasco D150 features reversible rotation, allowing you to match the clockwise or counter-clockwise requirements of the specific blower housing.

Is this a suitable replacement for a 1/4 HP furnace blower?
This is a standard furnace blower motor replacement for 115V systems requiring a 5-inch diameter motor with at least a 6-inch shaft length.
