The Vortex's 1.0 HP motor blasts air up to 125 ft - even through ducting. The rugged 12-inch axial fan blade and powerful static pressure make it ideal for high-pressure ventilation to or from inaccessible areas such as confined spaces. Stackable for storage, the Vortex is built in the USA of rugged rotomolded polyethylene and its housing has a limited lifetime warranty. UL/C-UL listed for safety.
