Helicopter Fan

The Helicopter Fan, Color - White is a large ceiling fan built to move a high volume of air in big industrial and commercial rooms. Its body is cast from strong aluminum plus the blade circle spans about ten feet - one unit can serve a wide floor area. A motor rated between 1 kW and 2 kW - about two horsepower - spins the blades slowly but pushes air steadily. Five blades, shaped for smooth flow, stay balanced but also quiet while they drive air. At top speed the fan delivers tens or hundreds of thousands of cubic feet of minute. The motor runs on standard three phase industrial power. One fan ventilates and cools multiple thousand square feet - warehouses, plants as well as large public halls use it - it uses little energy and needs little upkeep.
