The Warpfive Sidewinder Stove Fan has a compact design and operates across a broad range of temperatures. This engine works well on any medium to hot fire and starts operating at 110° C (230° F). Named the Sidewinder for its dual pulley and belt operating mechanism – it has an intriguing design that is captivating to watch and highly functional. The Sidewinder propeller is 220mm (8.6 inches) in diameter. Due to its clever design the Sidewinder’s RPM is increased via the stepped up pulley ratio, resulting in an impressive 320 CFM (cubic feet per minute) of air moved.
