Our SHEVTEC�range of fans are designed to extract hot gases from corridors and lobbies via smoke shafts. All fan sets are tested to European Standard EN12101-3 and fitted as part of a fire engineered solution. There are advantages in using mechanical smoke shafts over code compliant natural ventilation shafts, namely,�the shaft sizes are usually smaller than ABD compliant shafts
