Air cleaner element having incorporated sorption element

摘要

A gaseous cleaner element comprising a housing having a gas inlet and a gas outlet with a gas stream formed therebetween. An immobilized mass of sorption material formed in a desired shape is mounted in the housing, the gas stream passing therethrough. A particulate filter layer is mounted in the housing adjacent to the mass, the gas stream passing therethrough. The particulate filter layer is mounted upstream of the sorption material mass. The air cleaner element can be used as a replacement to existing filter elements to provide sorption and particulate filtering to air circulation systems such as cabin air filter systems.
