Filter Box

In copier/printers the requirements for ozone removal, cooling and air filtration are normally met with separate non-contiguous air paths. A design is presented where the requirements are met with a single molded unit affording savings in cost and space.

Filter box 10 is a single molded unit consisting of several air chambers and spaces for three removable filters 11, 12, 13. The air chambers are individually sized to attain the proper air flow in the air paths.

Ozone laden air entering at inlet 14 is drawn through chamber 15, ozone filter 12, chambers 16 and 17, air filter 13 and exits at port 18. Cooling air drawn from the body of the copier/printer enters inlet 19, is drawn through chamber 17, air filter 13 and exits at port 18. Thus, cooling air and air from the ozone filter share a common chamber and air filter.

Air used for detack enters inlet 20, passes through air filter 11, chambers 21 and 22, and exits at port 23. This path is completely independent of the other air paths but is physically part of the same molded filter box 10.

Blowers attached at ports 18 and 23 provide the necessary air movement.
