Fire & Ventilation Technology
Trailer: short version
light-weight
and powerful

► powerful
The Mobile Ventilation Unit has a nominal air output of 210.000 m³/h. Depending on the operating and constructional
conditions it is possible to carry the multiple amount of air; during the ventilation of road traffic tunnels
an air output up to 1.000.000 m³/h was achieved.
► light-weight
The Ventilator (without the lift-rotation-tilt-device) with an impeller-Ø of 1.250 mm weighs only 320 kg (gasoline
engine).
► optimal fan adjustment
With the lift-rotation-tilt-device it is possible to adjust the Mobile Ventilation Unit perfectly to the constructional
conditions at scene of the operation.
► Water mist system
With the integrated water mist system it is possible to cool
down objects and hold down toxic gases. In still air a range
from 40 m to 50 m could be achieved.
► Non-collapsible duct system
The non-collapsible duct system can be used for suction and
pressure mode.
