HVAC Draft Inducer Blower Fasco 1/18 HP 115V Motor

Description

Product Overview

The Fasco A173 HVAC Draft Inducer Blower is engineered to provide consistent and efficient airflow for furnace exhaust systems. Featuring a 1/18 horsepower motor operating at 115 volts and 60 hertz, this unit delivers a steady 3450 RPM rotation speed, ensuring that combustion gases are expelled quickly and safely. The blower incorporates a sealed‑bearing 3.3 inch diameter fan wheel that operates with minimal noise and reduced wear, extending the service life of the motor while maintaining optimal performance.

Constructed from high‑quality steel and corrosion‑resistant components, the blower is built to withstand the demanding environment of residential heating systems. Its compact dimensions—14 x 12 x 9 inches—and lightweight design (approximately 5 pounds) make it easy to install in tight spaces, while the robust housing protects internal parts from dust, moisture, and temperature fluctuations. The motor’s electrical specifications—0.8 amp draw and a single‑phase AC design—provide reliable power consumption without overloading typical household circuits.

Compatibility is a key strength of this product. The A173 model aligns with a broad range of furnace manufacturers, including Fasco, Heil, ICP, Tempstar, Rotom, Dayton, Alltemp, and many others. This cross‑compatibility is achieved through a standardized mounting pattern and connector layout, allowing technicians to replace or upgrade existing draft inducer fans with confidence. The blower also meets industry standards for safety and efficiency, making it a trusted choice for both new installations and retrofit projects.

In addition to its mechanical and electrical attributes, the blower comes with a two‑year manufacturer warranty, reflecting Fasco’s commitment to quality and customer satisfaction. This warranty covers defects in materials and workmanship, providing peace of mind for homeowners and installers alike. The product is shipped with all necessary hardware, including mounting brackets, wiring harnesses, and a detailed installation guide, ensuring a smooth and hassle‑free setup process.

Usage

The A173 Draft Inducer Blower is ideally suited for residential heating applications where reliable venting of combustion gases is essential. It excels in single‑stage and multi‑stage furnace systems, delivering consistent airflow that helps maintain proper pressure differentials within the venting network.
