Coppus Air-Driven Reaction Fans

Rugged, cast aluminum housing and fan blade make these fans ideal for hazardous locations and demanding ventilation projects. The RF design utilizes action-reaction principles; compressed air is discharged through nozzles located at the tip of the fan blades providing extremely efficient, high-volume, low maintenance air movers.
