Abstract
An air filter system, with a replaceable cartridge, suitable for use in controlled environment systems such as computer information storage and retrieval devices. The system provides ease of maintenance, while providing a highly sanitized air stream to an optical device, over prolonged periods of operation, for temperature control of temperature sensitive areas. The system is comprised of a housing plenum located in the controlled environment system, the housing having a sliding filter tray, a plurality of air flow ports and a spring biased valve gate. When the filter tray is fully inserted in the housing, the valve gate is forced open so that the air flow is into the controlled environment, but when fully retracted the valve gate closes, causing the air to exit the system through an exhaust port.
