Farm building fan HELICOPTER

for air circulationceiling

The “Helicopter” units are equipped with 5 anodized aluminium blades with 22 cm wing carrier surface. The three-phase motors have 0.75 Kw (1 Hp) power for 11′ (3.30 m), 12′ (3.60 m), 14 ‘(4.30 m) and 15’ (4.70 m.)models. And 1.1 Kw (1.5 Hp) for the 21′ (6.30 m.) model and 1.5 Kw (2 Hp) for the 23′ (6.90 m.) model. The motors are designed and built for use at variable speeds. Gearboxes are of Italian design and manufacture, maintenance free, with angular contact bearings and coupling joint to the motor to optimize the transmission of power. The hub that connects the gearbox to the rotor is provided with a security system that prevents accidental separation of the rotor. The blades are equipped with winglets, which increase the efficiency of the fan. The airflow generated by “Helicopter”, at maximum speed, varies from 160,000 m³/ h for 11′ to 400,000 m³/h for 23′. The speed control can be implemented by automatic systems with temperature sensing. In this case, the software allows the operator to change the default values to suit the needs. An additional module allows to integrate ventilation with a large drop cooling system located on the rack.
