QBD Series – Economy Line Direct Drive Barrel Fan
Triangle Engineering’s QBD Series is our economy line of direct drive portable barrel fans, delivering reliable airflow at an affordable price. Built with a rugged steel barrel, OSHA-compliant spiral-wound guards, and deep-pitch blades, the QBD provides steady, economical cooling in shops, warehouses, and agricultural facilities without the short life cycle of disposable imports.
Available in 36″ and 42″ diameters, each unit uses a ½ HP, two-speed motor to move up to 13,200 CFM for dependable people and equipment cooling. Designed for mobility, the QBD rolls easily into position with no-flat wheels and a rear handle. Unlike throwaway fans, every QBD model is fully supported with readily available replacement parts—motors, guards, blades, wheels and switches—for quick shipment and years of continued use.
