Our portable ventilators are designed for 24-hour unattended operation at both off-road and on-road locations. They are for the exhaust or supply of air to drain culverts, water system piping, sewers, construction sights, buildings, elevator shafts and any other applications where large volumes of air are required. The fan features a non-overloading brake horsepower curve so the engine can’t bog down regardless of operating configuration.
