3 Proper use
The axial fans of the series AXC/AXR/AXCBF in the versions B, D, G, P, (K), (B) are intended for
installation in ventilation systems!
The axial fans of the series AXC/AXR/AXCBF in the versions B, D, G and P are ready-to-use products and are
used as components for ventilation appliances, machines and systems. With these fans, air can be sucked out,
inserted or also conveyed. As a standard, the fans are supplied with a thermal motor protection (PTC).
The fans can be installed both in channel systems and also with free suction via an admission nozzle and a
suction-side contact protection grid. Free blow-out via a contact protection grid is also possible following prior
consideration during design.
The axial fans may not be used in areas in which an explosion-capable atmosphere can be found. The fans are
not suited for suction of dusty or aggressive media or media with such a content of dust that operation of the
fan could be impaired by accumulation on the blades and on the fan housing.
• The maximum admissible operating data on the name plate apply to an air density ρ =1.2 kg/m³
(See level)and a maximum air humidity of 80 %. The fans are suited for an ambient temperature of
no more than 55 °C (pay attention to information on name plate). The temperature of the material
conveyed may not exceed 55 °C or fall below –20 °C.
• The maximum admissible temperatures stated above can be increased to an ambient temperature of
60 °C, 80 °C or even up to 100 °C (pay attention to precise information on name plate) by use of ISO H
motors. The temperature of the material conveyed may then not exceed 100 °C or fall below –20 °C.
• With the use of specic motors (pay attention to precise information on name plate), the fans can also be
used up to a maximum air humidity of 95 %.
• The motors cannot be voltage-controlled. Speed regulation is only possible via a customary frequency
inverter, e.g. Systemair FRQ or FXDM.
