Ducted AC Blower Motor

The Imperative: Generating Sufficient Airflow and Pressure to Distribute Conditioned Air Through Residential and Commercial Ductwork

The Ducted AC Blower Motor is the primary air-moving component in central air conditioning systems, furnaces, and air handlers. Its function is to drive the large centrifugal blower wheel, generating the volume and static pressure necessary to push conditioned air through the entire network of supply and return ductwork. We provide highly reliable motors in all key technologies: Standard PSC AC, High-Efficiency ECM (Electronically Commutated Motor), and Multi-Speed AC Induction, catering to both single-stage and variable-speed, high-SEER ducted systems.

For modern, high-efficiency ducted systems, our ECM motors (a type of BLDC/EC) are the preferred choice. They offer superior static pressure performance and maintain programmed airflow (CFM) even as filter loading and duct resistance change. This is critical for ensuring consistent comfort and minimizing temperature variations across multiple zones. The ECM's efficiency, particularly at the low speeds required for dehumidification or constant fan operation, results in major energy savings—a mandatory feature for high-tier ducted systems aiming for top SEER ratings and compliance with government efficiency standards.

Our motors are engineered for the demanding environment inside the air handler unit (AHU), often exposed to temperature extremes and internal condensation. They feature robust, low-noise bearings and specialized mountings (e.g., resilient cradle bases) designed to minimize the transmission of motor vibration into the air handler cabinet and the connected ductwork, a common source of system noise. Customization is offered in shaft diameter, length, and motor housing diameter to ensure perfect fitment into the blower assembly, whether belt-driven or direct-drive configurations are used.

We commit to providing motors that optimize the entire system's performance. Our ECM control modules can be pre-programmed with specific fan tables (CFM vs. pressure) to match the AHU manufacturer's specified airflow requirements perfectly. By selecting our Ducted AC Blower Motors, manufacturers ensure reliable, efficient, and quiet air distribution, the core function of any central HVAC system.
