Air filter operable for filtering cabin air in vehicles, agricultural machinery, construction equipment and other work machines

摘要

The invention relates to an air filter element of a passenger compartment for the driver's cab of agricultural and work machines, in particular with spraying and atomizing devices for pesticides and fertilizers, comprising 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.

主权项

1. A passenger compartment air filter element for filtering an air flow in a driver's cab of agricultural and work machines, comprising:
an adsorption filter layer comprising
a plurality of individual adsorption layers, each having:
a carrier stratum layer of a flat layer of filter medium or synthetic grid; anda bulk layer of activated carbon particles arranged on one side of the carrier stratum layer, the bulk layer of activated carbon particles fixed onto the carrier stratum layer by a plurality of adhesive dots applied on the carrier stratum or by means of a net of adhesive threads;wherein the plurality of adsorption layers are layered directly upon immediately adjacent absorption layers, onto either the carrier stratum layer or the bulk layer of active carbon of the immediately adjacent layers, to form the adsorption filter layer; a fine filter layer, in particular for separating aerosols; a circumferential sealing element operable for sealably separating a raw side from a clean side of a filter housing when installed into the filter housing.
