The rotor matrix is made for laminar airflow using alternating layers of flat and corrugated foil to provide a structure comprising small, triangular channels.
The illustrations left shows the number of segments for sectorized rotors of different dimensions
The rotor are either in one piece or sectorized. One piece rotor are made in diameters ranging between Ø300-2450 mm, while sectorized rotor have diameters ranging of Ø801-5000 mm. Sectorized rotor are divided into segments that are assembled when the rotor is installed.
The rotor are as standard manufactured for vertical installation, horizontal installation is an option and must be notified at ordering. One piece rotor up to Ø2100 mm may be installed horizontally, and sectorized up to Ø3200 mm.
