The Electric Ventry PPV Fan Model 20EM3550 is easy on your back and ears but high-performance and high output. This E-Fan is 15 Amp, variable speed, and GFCI-safe. It combines efficient three phase technology with the all-terrain three-leg design and aircraft-style Ventry Safety Propellers exclusive to Ventry Fans. At 10,500 CFM (thrust-verified!), this fan is appropriate for aggressive positive pressure attack and ventilation, not just post-knock down mop-up. Like all Ventry Fans, the 20EM3550 E-Fan is built rugged and strong but not bulky: it weighs less than 80 pounds, can be moved easily by one person, and fits in a small space (less than 2x2x2-feet).
