Five-bladed rotor produces a cool breeze even at low speed: Cordless fan UniversalFan 18V-1000 from Bosch for DIYers

With five rotor blades, the UniversalFan 18V-1000 moves a greater volume of air at the same speed than the more common three-blade fans. Bosch's own ‘JetBreeze Airflow Technology’ ensures quiet operation with the same maximum output of 1,000 cubic meters of air per hour. With its concentrated air flow, the battery-operated fan provides a pleasant cooling effect even at low speeds at distances of more than five meters.
