Abstract (en)
[origin: DE10251149A1] The fire smoke disperser has a by-pass flow generated around a building by an axial ventilator (2) using flaps (3.1) which are self closing and which open under a predetermined overpressure in the escape path. Compression springs keep the flaps closed until a set overpressure to provide an independent self regulating action. An Independent claim is also included for a method of keeping building escape routes smoke free using the ventilator system.
