The divided medium-pressure axial fans of the AXCBF-EX / AXC-EX series are available with rotor diameters from 250
to 1600 mm.
They can be used for temperature classes T1, T2, T3 and T4. They convey explosion-capable gases in Zone 1 and Zone
2 as well as groups IIA, IIB and IIC.
Ex d: The motor has motor protection through an integrated posistor (PTC) and is speed-variable through a frequency
converter.
For temperatures above +40 °C, the maximum motor load according to the following table is to be considered:
