Chopper fan

In the 90s the fan underwent the first transformations to be faster, in line with the needs of customers who operated higher performing machinery and therefore needed to adapt the entire production to the same new speed.
The dimensions have also been updated, with 9 different variants: from the smallest with a diameter of 35 cm up to 85 cm in diameter of the impeller, able to handle an air flow ranging from 300m3/h up to 30,000m3/h.

As of 2018, the fan has undergone a complete upgrade, improving performance and durability. These changes were greatly appreciated by customers, who could continue to use the same product already installed but with better performance.
