Mechanical smoke extraction system - advice, installation & maintenance
Mechanical smoke and heat extraction systems (MRA) use a fire gas fan on the roof, in the wall or inside a duct system of the corresponding building, which draws fire gases from the area to be extracted and discharges them to the outside. CWS recommends at least fans of temperature class F600 to prevent malfunctions caused by rising smoke gas temperatures during a fire.
Smoke extraction system for interior rooms
Mechanical smoke and heat extraction systems are used in buildings where it is not possible to install a light dome or natural smoke and heat extraction systems or where areas inside the building need to be ventilated. These can be, for example, multi-storey buildings, cellars, other interior areas and structurally connected rooms, such as sales areas of large department shops.
Fans for mechanical smoke extraction systems:
- Roof fans
- Wall fans
- Duct fans
- Axial fans
- Centrifugal fans
Maintenance of mechanical smoke ventilation systems: Mechanical smoke and heat extraction systems must be inspected by an expert and additionally serviced by a competent person every year.
