A diazo copy machine of the type utilizing ammonia vapors to develop exposed copy material and which utilizes a suction chamber for collecting and drawing off the ammonia vapors escaping from the development chamber and given off by developed copy material. The disclosed machine features an integrated ammonia vapor absorber canister which is mounted within the copier housing or secured by means of brackets to the rear of the machine housing and through which is directed the collected ammonia vapors by means of a plugin tube insertable in one end of the canister. This directs the ammonia vapor containing discharge from the suction chamber through the canister. In one version, the canister contains a composite of granular and fibrous absorbent materials to insure complete absorption of the ammonia vapors and to avoid channelization of the materials. In this latter version, the canister is inclined upwardly from the point whereat the ammonia vapor containing exhaust is directed into the canister to provide further protection against channelizing of the absorbent material within the canister.
