Abstract
A novel apparatus for the collection and removal of ozone generated during the operation of machines, such as an electrostatographic copying machine, is disclosed which includes the substantially complete collection of ozone generated by the use of an apertured plenum at the point of ozone generation, and the substantially complete removal of the ozone collected by the use of a fixed bed filtering device which has a large bed area to volume ratio. The disclosed apparatus permits the substantially complete collection of all ozone generated in a relatively small volume of air accomplished with a low pressure drop, so that the ozone collection and removal system would not interfere with the normal operation of the electrostatographic copying machine.
