These roof fans are suitable for extracting large air volumes. Therefore they are particularly designed for air exchange of large volume premises and plants.

Main features of TACC series are high strength, easy of installation and maintenance, high effi ciency (thanks to axial impeller with airfoil blades). This range has the possibility to be easily ducted and, if required, the possibility of making a version for air intake (with reverse flow). The use of the TACC series is foreseen for clean air with max. temperature of 50°C.
