Patented TANDEM® Blade takes advantage from the combination of two separate profiles held together with the scope to delay the separation of the airflow around the airfoil to reach extremely high efficiency levels.

TANDEM® Blade represents the best solution for Energy Saving projects (reducing the absorbed power, but maintaining the same cooling capacity) and for those projects where cooling performances must be increased maintaining the same power consumption and motor size.
Available from 8ft (2.4m) to 22ft (6.7m) with manual and auto-variable pitch configuration, TANDEM® Blade utilizes the FLEXI Blade technology with all the related technical advantages and cost savings.
