"BIG VENTO" fans are designed to meet major challenges, which are: move and circulate a vast amount of air without noise or turbulence throughout the property, accomplish the work using the lowest possible power to work with the evaporation system of the human body to optimize the cooling effect.

The fans’ diameter is between 3 and 7 meters, spinning at very low speeds from 47 to 100 RPM instead of 800 RPM like in common 90 cm diameter fans, and consume 0.396 kW up to 1.5 kW of electricity, reducing thereby operation costs by up to 39 cents per hour.
