Home Fire protection Training Documentation Product Installation Service & maintenance References plug Q-fog Smoke hatches Fire alarms and evacuation alarms Smoke cap Smoke hatches are used to evacuate smoke from stairwells, shops, warehouses and the like in the event of a fire. The purpose is to lower the temperature, reduce smoke damage and prevent the spread of fire. Flue and fire gases prevent evacuation, damage buildings and goods, make firefighting more difficult and are dangerous both for people in the building and for rescue personnel. AB Upplands Brandservice, Aros Brand and Nerikes Brandservice deliver new doors, renovate older doors and replace old and damaged doors with new and modern fire gas fans. Fire fans are available in different designs for mounting in ceilings or for placement in facades. They can be fitted with transparent lids to let in daylight. The doors are opened manually or automatically in the event of a fire. Opening is normally via gas spring. In the standard version, the door is held back by a fuse plate that trips at 72o C and the gas spring pushes up the door. Alternatively, the door can be held back by the holding magnet and opened via a fire alarm or a push button. Smoke doors can also be fitted with an electric motor and can be opened and closed electrically and then included as part of the building's comfort ventilation. The doors are delivered as a complete unit ready for mounting on the ceiling. Each delivery is customized so that the design, size, color and choice of material fits the existing roof and the need for ventilation. We also perform regular service and maintenance on smoke hatches. Do you want to know more?
