Abstract
A filter arrangement in the intake airflow of a heating or air-conditioning system of a motor vehicle, comprising two filters (preferably activated carbon filters), arranged offset and at a distance on behind the other relative to the direction of air flow, through each of which a partial volume of the air to be filtered flows. An air-guiding device is arranged upstream of the filters which feeds air proportionately to the two filters to produce a uniform supply. A wall capable of preventing flow round the rear filter, is provided between the two filters.
Claims6
Filter arrangement inserted in the intake airflow of a heating or air-conditioning system of a motor vehicle, comprising first and second filters arranged offset and at a distance one behind the other through each of which a partial volume of the air to be filtered flows, said first filter being disposed upstream and at least partially in front of said second filter relative to the direction of air flow, a wall connected between said filters and adapted to prevent air flow around the second filter so that said second filter can transmit airflow over its entire surface, and air guiding means disposed upstream of said filters for controlling the relative volume of air flow through said filters to produce a uniform supply.
