Abstract
A copying machine such as a diazotype copier which uses developing reagents which produce fumes is provided with an economical attachment for scavenging any fugitive gas traces and passing them through a treatment cartridge. A manifold mounted in the machine housing has an insert strip with air access openings which can be sized to suit the requirements of a particular copying machine. An air conduit hose has a snap connection with the manifold and with one end of a blower housing the other end of which is attachable to and readily detachable from a unitary disposable supply package which is floor supported and supports the blower housing. The supply package includes a supply of gas generating development material in one portion, and in the other, a gas treatment cartridge of inexpensive disposable character which is so constructed as to pass incoming air down through a central tube and then upwardly through a tube-surrounding space containing gas treatment material and then into the surrounding atmosphere.
