Smoke Extraction Motors
Our new certified smoke extraction motors
have been specially developed for buildings
or construction sites with smoke control systems.
This includes buildings frequented by the public
in large numbers, such as discotheques,
shopping centers, movie theaters, airports,
enclosed car parks as well as industrial buildings,
staircases, tunnels and so on.
Our smoke extraction motors can even cope with
high ambient temperatures safely.
In the event of an accident, they reduce the heat
loading on the building and keep access and
escape routes smoke-free.
The double-function motors operate as follows:
- As fan motor for operation under normal conditions
- Operation under fault conditions as fan motor at high ambient temperatures (200°C, 300°C, 400°C) and minimum operating time stipulated according to norm
Temperature-time Classification in Accordance with EN 12101 - 3 June 2002

| Inverter |
Insulation of the smoke extraction motors
is designed to permit operation with a
inverter at voltages - 500V without restrictions.
This also applies for operation with a PWM
inverter with Voltage peak times ts >
0.1 µs at the motor terminals.
