Fasco D1179 Motor

The Fasco D1179 is a heavy-duty shaded pole centrifugal blower motor designed for precision air movement in demanding HVAC applications. This 1/30 HP replacement motor operates at 115 Volts and maintains a consistent 3000 RPM single-speed profile. Engineered with a 3.3-inch frame diameter and sleeve bearings, it ensures high reliability and quiet operation in localized cooling and exhaust systems. As a cross-reference motor, it serves as the direct drop-in replacement for model 579 and JA1M147, matching the original mechanical footprint and electrical parameters. The thermally protected design prevents winding failure during continuous duty cycles, making it a staple for contractors maintaining older ventilation blowers and furnace draft inductors. Its clockwise lead end (CWLE) rotation and specific shaft dimensions allow for rapid field installation without the need for mounting modifications or bracket adjustments.

• OEM Compatibility: Direct mechanical match for the Fasco 579 and JA1M147, ensuring exact alignment.
• Efficient Performance: Shaded pole design provides high reliability for low-torque centrifugal fan applications.
• Durable Construction: Features all-angle sleeve bearings for versatile mounting and reduced vibration.
• Thermal Protection: Internal automatic reset thermal overload protection preserves motor integrity under high-heat conditions.
• Standardized Specs: 3.3" diameter motor housing fits standard mounting configurations for quick service calls.

Common HVAC Questions

What are the wiring requirements for the Fasco D1179?
This is a standard 115V single-speed motor. Installation involves connecting the two primary leads and ensuring a solid ground, typically mirroring the wiring used in the JA1M147 it replaces.

Can this motor be used in high-moisture environments?
While the D1179 is built for durability, it is an open ventilated motor. It is best suited for dry-air movement within blowers and inductors where it is shielded from direct moisture or heavy contaminants.

Does the D1179 include the blower housing?
No, this is the replacement motor only. It is designed to be swapped into your existing centrifugal blower assembly, reusing the original housing and wheel.
