Mechanical smoke extraction system

Mechanical smoke extraction systems safely discharge smoke gas from interior building rooms to the outside via ventilation ducts by means of fire gas ventilators.

Mechanical smoke extraction system - advice, installation & maintenance

Mechanical smoke extraction systems are installed in interior rooms or in rooms in which no sufficient opening to the outside can be installed. Mechanical smoke extraction systems can be found, for example, in basement rooms, underground garages, sales premises or places of assembly.

 

How mechanical smoke extraction systems work

The mechanical smoke extraction system is connected to a ventilation system as well as fire gas ventilators. Heat and smoke are conducted to the outside through ventilation pipes. At the same time, the mechanical smoke exhaust system ensures that fresh air is introduced into the building through other openings or supply air fans (air exchange). CWS recommends at least fire fans of temperature class F600 (up to 600 °C/120 minutes) for mechanical smoke extraction systems. This can minimise malfunctions caused by an increased smoke gas temperature during a fire. The fire gas fan can be installed on the roof, on the wall or in a ventilation duct.

 

Maintenance of mechanical smoke extraction systems

Mechanical smoke extraction systems must be serviced annually by a competent person. In addition, the operator is obliged to carry out a visual inspection once a year.

Advantages

  • Low-smoke rooms possible in a short time
  • Fire gas ventilators ensure the safe discharge of the toxic smoke gas
  • Air exchange for interior building areas
  • Alternative for buildings where skylight domes or natural smoke extraction systems are not possible

Sustainability

Mechanical smoke ventilation systems stabilise the building structure as they reduce the heat load in the building.
