Ruck Air Movement 20 inch 6851 CFM Axialine Tubeaxial Fan

Deliver a robust, high-volume airflow with the Ruck Air Movement 20-Inch Axialine Tubeaxial Fan AL 500 D4 01.

Built for engineers, contractors, and facility managers who need powerful yet energy-smart ventilation, this industrial tubeaxial fan moves up to 6,851 CFM in 20-inch duct systems. Whether you’re upgrading a warehouse exhaust line, balancing HVAC supply air, or improving air changes in a manufacturing space, it offers a reliable blend of performance, efficiency, and durability.

Key Features and Benefits of the Ruck Air Movement 20-Inch Axialine Tubeaxial Fan

• High-Capacity Airflow: Quickly removes heat, fumes, and parking garages or duct runs, improving indoor air quality and occupant comfort.
• CFD-Optimized Impeller: The computer-modeled blade angles reduce turbulence and noise while maximizing static pressure up to 360 Pa, making it ideal for long duct stretches or filter banks.
• IE3-Efficient Motor: Pair with a VFD (20 to 60 Hz) to match airflow to real-time demand, lowering energy costs during off-peak periods.
• Wide Temperature Range: The powder-coated steel construction allows continuous operation from ‑4 to 140 degrees F, keeping processes running in cold storage, hot workshops, and everything in between.
• Reliable IP Protection: An IPX4 rating shields the entire unit from light splashes of water, while an IP55 terminal box safeguards electrical connections against dust and moisture.
• Quick-Fit DN500 Flange: Standard 20-inch connection integrates seamlessly with existing ductwork, reducing installation time.
• Low Operating Current: Draws minimal amperage for a fan of its size, freeing up electrical capacity for other critical equipment.

Engineered Airflow for Demanding Environments

Every component of the Axialine fan is tuned for real-world industrial performance. Optimized blade angles and multiple frequency options let you calibrate volume flow to the exact requirements of your space, ramping up during peak production, then dialing back to save energy overnight or between shifts. 

The coated steel impeller resists abrasion from airborne particles, making it a smart choice for woodworking shops, welding bays, and light-duty process exhaust. Meanwhile, the unit’s balanced design keeps vibration in check, protecting bearings and minimizing transmitted noise through duct walls.
