Abstract
A system cleans or dusts devices, such as optical or photographic equipment or the like, with pressurized air from a chamber. The chamber is filled with air through an air inlet valve which may be connected to an air pressure source, such as a conventional tire pump, or may have a built-in pump connected thereto. As a result, when air is depleted from the chamber, the chamber may be re-filled for repeated use of the system.
