OVERVIEW

Are You Struggling With Heat and Stagnant Air? This 42" Direct-Drive Drum Fan Moves High-Volume Air to Cool Large Work Areas Fast

Heat rarely spreads evenly in warehouses and industrial spaces. It builds up around dock doors, production lines, and equipment, while hot air settles overhead. Smaller floor fans can help locally, but they often can’t move air far enough to matter in large, open areas. That’s where a full-size drum fan comes in.

The cooler HD fan from Triangle Engineering is a 42 inch portable, direct drive unit built to move a high volume of air across wide spaces. With airflow capacity in the tens of thousands of CFM (13,000+), it pushes air down long aisles and across open bays, helping reduce hot spots and improve overall air circulation in high-ceiling facilities.

In non-conditioned or partially conditioned spaces, increased air movement improves comfort by enhancing evaporative cooling on the body. Workers feel cooler, and equipment benefits from reduced heat buildup around chargers, compressors, and staging zones. Increased air movement is also recognized by OSHA as a practical way to help manage indoor heat stress.

This fan also supports general ventilation. When aimed toward open dock doors or exhaust points, it helps sweep out stagnant air, fumes, and odors commonly found in shipping, loading, and production areas. In workshops and repair bays, that same airflow helps dilute welding fumes, solvent vapors, and airborne dust.

The direct drive motor eliminates belts and pulleys, reducing maintenance and improving reliability during long operating hours. Fewer moving parts mean consistent performance and less downtime in demanding industrial environments.

Built on heavy-duty wheels, the fan can be moved quickly between work areas as needs change throughout the day. One unit can often replace multiple smaller fans, simplifying power requirements and floor layout. It fits naturally alongside other industrial warehouse fans and complements larger portable ventilation solutions. Often called a barrel fan, this design is chosen when strong, directional airflow and durability are the priority.

SPECIFICATIONS

FEATURES

• 42" High-Velocity Airflow for Large Spaces (13,600 CFM)
  The 42-inch blade diameter delivers powerful, wide-area airflow designed for warehouses, factories, and workshops where smaller fans can’t reach far enough. Ideal for long aisles, open bays, and high-ceiling environments.

• Direct-Drive Motor Eliminates Belt Maintenance
  A ½ HP direct-drive motor removes belts and pulleys from the equation, reducing maintenance, downtime, and performance loss over time—especially important for continuous industrial use.

• Moves Heat, Fumes, and Stagnant Air Fast
  High CFM output helps break up hot spots, sweep stagnant air toward open doors or exhaust points, and dilute fumes or odors in loading docks, production areas, and repair bays.

• Improves Worker Comfort and Heat Stress Conditions
  Increased air velocity enhances evaporative cooling on the body, helping workers feel cooler in non-conditioned or partially conditioned spaces where HVAC alone isn’t enough.

• Rugged Steel Drum Built for Industrial Environments
  The painted steel housing is designed to withstand daily use around forklifts, pallet jacks, and busy shop floors without compromising performance or safety.

• TEFC Motor Rated for Continuous Duty
  The Totally Enclosed Fan Cooled (TEFC) motor is suited for dusty, industrial conditions and long run times, providing dependable operation across multiple shifts.

• Portable Design with Heavy-Duty Mobility
  Built-in wheels and a balanced frame allow quick repositioning between work zones, dock doors, and staging areas—one fan can serve multiple locations throughout the day.

• Simple 115V Plug-and-Play Operation
  Runs on standard 115V single-phase power with a 10-foot cord, making it easy to deploy without special wiring or electrical upgrades.
