Engineered for reliable rooftop ventilation, the Canarm ALX105-DD033EC downblast exhauster uses an electronically commutated direct-drive motor to remove stale or contaminated air from offices, warehouses, and light industrial facilities. The 10.5-inch spun aluminum design pairs durability with energy-conscious technology, giving you a straightforward solution for exhausting air while meeting today’s efficiency expectations. Key Features and Benefits of the Canarm ALX105 10.5-Inch Spun Aluminum EC Exhauster Energy-Saving EC Motor: Electronically commutated technology delivers up to 82 percent motor efficiency, trimming electrical usage by as much as 70 percent compared with traditional permanent split-capacitor motors. Adjustable Airflow: A built-in potentiometer and 0-10V terminals let you dial fan speed from 425 to 1,800 RPM. It can be controlled remotely up to 50’ using a remote mount potentiometer or 0-10V. Flexible Installation: This model can be installed as either a rooftop or wall-mounted exhaust fan, giving installers greater flexibility in how the fan is placed and used. Consistent Power: The non-overloading backward-inclined wheel prevents motor overloading even as pressure changes. Corrosion-Proof Housing: Spun-aluminum construction will not rust, chip, or peel, making it ideal for coastal installations and harsh weather environments. Compact Footprint: This fan model fits 15-inch roof openings. Dual-Voltage Versatility: Runs on single-phase 120 or 240-volt power at 50 or 60 hertz, simplifying integration across job sites. Versatile Installation Whether you are replacing an older fan or outfitting a new build, the ALX105-DD033EC simplifies placement. It fits a 15 inch roof opening, and stands only 18 inches high, so clearance above the roof deck is minimal. Single-phase 120/240-volt wiring eliminates the need for three-phase service.
