PrintAir-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.
RF-20, RF-24 Features
- For 20 inch (50.8 cm) to 24 inch (60.96 cm) tank man ways
- 11,000 to 16,900 cfm (18,689 to 28,713 m3/hr) at 80 psig
- Use for fresh air supply or fume exhaust
- Can be carried or rolled to job site
- Spark resistant cast aluminum housing and fan blade
- Permanently lubricated bearings
- Flanges mate with 20-inch (508mm) and 24-inch (610mm) API tank opening
