Definitions
- tubular bodies closed or perforated, preferably with different pH values, ie strongly acidic and strongly alkaline, are drawn into the channel one above the other and thus prevent pest infestation.
- the material itself can also have a hole-like character and, for example, be strongly alkaline or strongly acidic
- the inserted film as a one-piece pipe system or as a perforated pipe system, can have the opposite pH value or the equivalent pH value, which depends on Which area of the world the ventilation and / or air conditioning technology is used for, and then the question arises as to which bacterial and fungal cultures occur at which pH in the given area.
- the strongly acidic and / or strongly alkaline strips arranged in the duct can cause a thorough mixing of the air flow, as a result of which the entire air flowing through is acted upon by the change from alkaline to acid.

Abstract
Une gaine d'aération ou de climatisation pour un dispositif de ventilation présente une surface conçue pour avoir une action bactéricide ou fongicide. Cette configuration permet un traitement biochimique de l'air circulant dans les gaines. Pour améliorer encore l'action biochimique, il est proposé que la surface intérieure présente, dans le sens de circulation de l'air, des sections striées alternées et séparées, dont les unes sont conçues pour être fortement alcalines et les autres fortement acides.A ventilation or air conditioning duct for a ventilation device has a surface designed to have a bactericidal or fungicidal action. This configuration allows biochemical treatment of the air circulating in the ducts. To further enhance the biochemical action, it is proposed that the inner surface has, in the direction of air flow, alternating and separate ridged sections, some of which are designed to be strongly alkaline and others to be strongly acidic.
