Info & Guides

The Canarm ALX210-DD100EC 21-inch Spun Aluminum Direct Drive 1 HP EC Motor Downblast Exhauster is a reliable solution for exhausting stale, warm, or contaminated air from commercial and industrial spaces. Built for roof tops or wall mounting, it pairs rugged construction with an electronically commutated motor to keep air moving efficiently across warehouses, factories, and office buildings.

Engineered around a direct drive design, this downblast ventilator delivers consistent performance without belts to adjust or replace. You gain variable speed control, impressive airflow, and durable aluminum components that stand up to demanding environments.

Key Features and Benefits of the Canarm ALX210-DD100EC 21-Inch EC Motor Downblast Exhauster

  • Energy-Saving EC Motor: Reduce operating costs with a one-horsepower electronically commutated motor that reaches up to 82 percent efficiency and cuts energy use by as much as 70 percent compared with traditional PSC motors.

  • Variable Speed Control: Adjust airflow from 425 to 900 RPM for precise ventilation that matches changing indoor conditions. Can be controlled remotely up to 50’ using a remote mount potentiometer or 0-10V.

  • High Airflow: Move up to 4,400 cubic feet per minute at 0.0 inches w.g. static pressure, ensuring rapid air exchange for large, open areas.

  • Direct Drive System: Eliminates belts, pulleys, and routine tension adjustments, lowering maintenance requirements over the life of the product.

  • Durable Housing: The spun aluminum housing is a lightweight, corrosion-resistant construction that resists rust, chipping, or peeling, even in harsh outdoor settings.

  • Non-Overloading Design: The backward-inclined aluminum wheel maintains stable energy draw across the speed range, protecting the motor during variable static pressure conditions.

  • On-Board Speed Adjustment: Use the built-in potentiometer and LED display for quick setup, or connect a 0–10 volt controller or remote potentiometer up to 50 feet away for convenient, ground-level control.

  • Dual-Voltage: Operates on single-phase 120 or 240 volts at 50 or 60 hertz, simplifying electrical planning across different job sites.

  • Quick-Release Latches: Easily access the motor and other internal parts without tools for inspection or cleaning, minimizing downtime.

  • Bird Screen: This included a protective screen that prevents debris, nesting, and animal activity.

Installation Flexibility

Whether you are replacing an aging rooftop fan or adding exhaust to a new structure, the ALX210-DD100EC adapts easily. It fits in a 29 inch opening, and it ships ready for either 50 or 60-hertz power connection, simplifying projects. Optional gravity or motorized dampers prevent backdraft when the fan is idle, while optional field-installed disconnect switches support local code compliance. 

Sylvane’s Expert Take

If energy efficiency and low maintenance top your priority list, this Canarm exhauster delivers. The EC motor’s variable speed capability lets you fine-tune airflow and trim power consumption, while the all-aluminum build resists weather and corrosion for years of dependable service.

For professionals seeking a cost-effective, high-performance ventilation solution, the ALX210-DD100EC is a smart pick.
