Key Features and Benefits of the Canarm ALX135-DD075S 13.5 in. Spun Aluminum Direct Drive Downblast Exhauster

  • 3/4 HP Exhaust Motor: The Canarm ALX135-DD075S has a 3/4 horsepower motor that is capable of outputting exhaust airflows of up to 2,134 CFM (at 0.0 inches w.g.) and has a max fan speed of 1,650 RPM.

  • Dual-Voltage Wiring: Connect to 120-volt or 240-volt power supplies at 50 or 60 Hz, offering flexibilty in building installations.

  • Tool-Free Access: Quick-release latches open the top for direct motor and wheel access, reducing downtime during inspection or cleaning. Includes a protective screen that keeps birds and debris out.

  • Dependable Output: The non-overloading, backward inclined wheel design prevents motor overloading even as pressure changes.

  • Durable Design: The corrosion-resistant spun-aluminum housing will not rust, chip, or peel in harsh rooftop conditions, reducing long-term maintenance.

  • Downblast Configuration: Exhausts air directly onto the roof surface, preventing rain ingestion while dispersing stale air away from wall openings.

  • Roof or Wall Mounting: Use standard curbs, brackets, or sleeves to adapt the fan to rooftop decks, sidewalls, or curb caps. Includes a bird screen to keep debris and wildlife out of the fan cavity. It is designed to fit 17-inch roof openings.

Pressure-Rated Output

The ALX135-DD075S continues to supply 2,025 CFM at 0.25-inches w.g. static pressure and 1,593 CFM at 1.0-inches w.g. static pressure, helping you maintain target air changes even as resistance climbs. These AMCA Certified values simplify load calculations.
