A. O. Smith Century HF3H7078N Compressor Motor

A. O. Smith Century HF3H7078N Compressor Motor is a compact, 1/3 horsepower unit designed for 115V operation in air compressors. The model is listed with a speed rating of 1100/3 RPM, indicating a low‑speed drive suitable for light‑duty compression tasks where steady torque is important. As part of Century’s family of compressor motors, HF3H7078N represents AO Smith’s lineage of reliable, OEM‑style components used in small to mid‑sized machines. The 115V electrical requirement aligns with common residential and workshop electrical supplies, enabling straightforward wiring for compatible equipment. Installation details such as mounting pattern, shaft size, and enclosure type are equipment‑specific and vary between applications, so users should consult the original equipment installation instructions or the motor’s technical datasheet to confirm fit and compatibility. With its 1/3 HP rating and clearly defined model number, HF3H7078N serves as a targeted replacement option when a Century/A.O. Smith compressor motor is needed for lower‑power, steady‑duty operation.
