GAMAK smoke extraction motors drive smoke exhaust and pressurisation fans to clear smoke quickly during a fire. They help keep escape routes visible and give fire crews access to the building.
The series is offered in classes F300 and F400: the motors are certified to run for at least 2 hours at 300 °C and 400 °C respectively. Class H insulation, IP55 protection and a cast iron housing ensure stable operation under heavy thermal load, and S1 continuous and S2 short-time ratings allow use for both everyday ventilation and emergencies.
Two mounting types are available: foot-mounted standard motors and footless pad-mounted motors fixed to the fan casing in B30 arrangement. Frames 80–250, 0.75–55 kW and IE3 efficiency.
