Struggling With Hot, Stagnant Air in Your Facility? This 42" Direct-Drive Drum Fan Delivers Powerful Airflow That Keeps People Comfortable and Work Moving

Hot, stagnant air makes work harder than it needs to be. This 42" QBD Direct-Drive Drum Fan from Triangle Engineering is built for large commercial and industrial spaces that need strong, targeted airflow without modifying existing HVAC systems.

This drum fan delivers high-volume air movement that creates real air velocity across workstations, dock doors, production lines, and open bays. While it may not lower the actual air temperature, the increased airflow helps people feel cooler by speeding up evaporation—often the simplest and most effective form of heat relief in warehouses and factories.

In warehouse environments, airflow problems tend to show up near dock doors, under mezzanines, and in long aisles where air settles. This fan helps break up those stagnant pockets, improving circulation and supporting air dilution around forklifts, battery-charging areas, and packaging lines. The result is a space that feels more comfortable and less heavy during long shifts.

Factories benefit in much the same way. Localized heat near ovens, presses, welding stations, or assembly lines can overwhelm central systems. A high-velocity fan like this pushes air across those zones, helping move heat toward exhaust points and supporting heat-stress mitigation without permanent installation.

In workshops and service bays, the impact is immediate. One wide airstream can cover multiple bays, helping dry floors, equipment, and parts faster after cleaning. Fewer smaller fans are needed, which keeps spaces clearer and airflow more consistent.

The direct-drive design eliminates belts, reducing maintenance and keeping airflow steady over long run times. With fewer wear parts, it’s well-suited for facilities that need dependable equipment with minimal upkeep. The 42-inch size offers an ideal balance—wide coverage and long throw, yet still portable enough to roll through standard doors and around equipment.

Straightforward airflow. Proven reliability. Built to cooling where it counts.

FEATURES

• High-Volume Airflow for Real Heat Relief
  Moves up to 13,200 CFM with a 42" blade, creating strong, directional airflow that helps people feel cooler through increased air movement—even when room temperatures don’t change.
  
  
• Reliable Air Movement for People, Equipment, and Drying
  Ideal for cooling workstations, ventilating hot zones, assisting with fume and dust dilution, and speeding up drying of floors, equipment, and washed parts.
  
  
• Direct-Drive Design with Fewer Failure Points
  The direct-drive motor eliminates belts, reducing routine maintenance, efficiency loss, and downtime—especially valuable in busy warehouses, factories, and workshops.
  
  
• HP Two-Speed Motor for Flexible Control
  A ½ horsepower, two-speed motor (745/570 RPM) lets you balance airflow and noise depending on the task, whether it’s spot cooling workers or drying floors after cleaning.
  
  
• Built for Continuous Industrial Duty
  Rated for continuous operation, this fan is designed to run for long shifts without overheating, making it suitable for seasonal heat relief or daily use near hot processes.
  
  
• Rugged Steel Barrel with OSHA-Compliant Guards
  Features a durable steel housing and spiral-wound OSHA-compliant guards, providing protection and long service life in demanding industrial environments.
  
  
• Portable and Easy to Position
  Integrated no-flat wheels and a rear handle make it easy to roll into place, aim airflow where it’s needed, and reposition as layouts or work zones change.
