A 42-inch drum fan is a heavy-duty floor fan built to move a huge amount of air through larger spaces. It’s a great option for keeping guests more comfortable at outdoor events, large tents, garages, shops, barns, and warehouses.

Most 42” drum fans have a large metal housing, oversized blades, wheels for moving it around, and one or more speed settings. Depending on the model, airflow can be well over 15,000 CFM.
