Abstract
The invention relates to an air filter element, particularly for a passenger compartment for the driver's cab of agricultural and work machines, in particular with spraying and atomizing devices for pesticides and fertilizers, having an adsorption filter layer with activated carbon, a fine filter layer in particular for separating aerosols and a circumferential sealing for separating the raw side from the clean side during installation into a filter housing.
Claims23
An air filter element for filtering an air flow, comprising:
- an adsorption filter layer including:
- a plurality of individual adsorption layers, each having:
- a carrier stratum layer of a flat layer of filter medium or synthetic grid;
- and
- a bulk layer of activated carbon particles arranged on one side of the carrier stratum layer, the bulk layer of activated carbon particles layered onto the carrier stratum layer and fixed to the carrier stratum layer by an adhesive;
- wherein the plurality of individual adsorption layers are layered directly upon immediately adjacent individual absorption layers, onto either the carrier stratum layer or the bulk layer of active carbon of the immediately adjacent individual absorption layers, to form the adsorption filter layer;
- a circumferential sealing element operable for sealably separating a raw side from a clean side of a filter housing when the air filter element is installed into the filter housing.
