Title (EN) ODOUR SUPPRESSING AIR FILTRATION SYSTEM
(FR) SYSTÈME DE FILTRATION D'AIR SUPPRIMANT LES ODEURS
Abstract:
(EN) The invention relates to an air filtration system comprising a fan or pump that pumps air through a sequence of filters, where the sequence of filters comprises an active carbon filter (AC, AC1- 2), and an odour suppressing filter (S). The odour suppressing filter (S) comprises a main active substance that acts on the air by suppressing odours, where the main substance is a hygroscopic substance. With such an odour suppressing filter (S) undesirable odours coming from the active carbon filter are suppressed or prevented. The odour suppressing filter (S) has as its main active substance a hygroscopic salt. The odour suppressing filter (S) may have as its main active substance one or several of sodium chloride, potassium chloride or magnesium chloride. In yet another embodiment, the filter sequence further comprises at least a Zeolite filter (Z), where the Zeolite filter (Z) is arranged after all the active carbon filters (AC, AC1-2) in the filter sequence. The Zeolite filter (Z) may also be arranged after the odour suppressing filter (S).
(FR) L'invention concerne un système de filtration d'air comprenant un ventilateur ou une pompe qui pompe de l'air à travers une série de filtres, laquelle série de filtres comprend un filtre à charbon actif (AC, AC1-2), et un filtre de suppression des odeurs (S). Le filtre de suppression des odeurs (S) comprend une substance active principale qui agit sur l'air en supprimant les odeurs, la substance principale étant une substance hygroscopique. Avec ce filtre de suppression des odeurs (S), les odeurs indésirables provenant du filtre à charbon actif sont supprimées ou évitées. Le filtre de suppression des odeurs (S) comprend comme principal substance active un sel hygroscopique. Le filtre de suppression des odeurs (S) peut avoir comme principale substance active une ou plusieurs substances parmi le chlorure de sodium, le chlorure de potassium ou le chlorure de magnésium. Dans encore un autre mode de réalisation, la série de filtres comprend en outre au moins un filtre à zéolites (Z), ce filtre à zéolites (Z) étant placé après tous les filtres à charbon actif (AC, AC1-2) dans la série de filtres. Ce filtre à zéolites (Z) peut également être disposé après le filtre de suppression des odeurs (S).
