Abstract (en)
[origin: WO2004103475A1] Disclosed is a ventilation system (10) providing NBC protection in at least one closed security space and/or protective space (12) having permanent pressure slightly above atmospheric. Said ventilation system (10) essentially comprises an air inlet (16) and an air outlet (18), an anti-explosion valve (28), a prefilter (26), a filter (38) for suspended matter, an activated carbon filter (40), and an air-conveying device for sucking in the air that is to be purified and distributing the purified air. At least one of the following three built-in elements is arranged in the inventive ventilation system (10): an anti-explosion valve (28) that is combined with and cooperates with the prefilter (26); a combined activated carbon filter (40) made of activated carbon which is specifically effective against harmful biological and/or chemical substances and radionuclides; an air pump that is embodied as a double pair of bellows (52).
