摘要： Provided is a safety cabinet that prevents oversights in airtightness tests and HEPA filter penetration ratio tests even if a pathogen or the like leaks from a workspace wall surface in the interior of the safety cabinet. The safety cabinet includes: a work surface at the bottom of a workspace; a front panel at the front of the workspace; a work opening section below the front panel; and a first air purification means that filters exhaust air that is air discharged from within the workspace. The safety cabinet is characterized in that the non-workspace sides of a side wall surface and a back wall surface of the workspace are formed by an outer wall of a device with prescribed airtightness performance.

摘要： The purpose of the present invention is to provide a clean air device that can reduce the risk of contamination due to static electricity. Provided is a biosafety cabinet or a clean air device that connects a biosafety cabinet and a clean booth, wherein a static eliminator (ionizer) that generates a corona discharge by way of concentrating an electric field on a needle-shaped discharge electrode and eliminates static with ionized air is disposed directly above an air flow branching point where air supplied to a work space branches to the front face and to rear face inside the biosafety cabinet.

摘要： The purpose of the present invention is to reduce the risk of contamination in a clean air device in which a safety cabinet and clean booths are coupled. To achieve this, a clean air device in which a cabinet and clean booths are coupled, is configured such that the cabinet is equipped with: a work space which is formed on the inner side of a front shutter; and a circulation path which is formed from the lower surface, side surfaces, rear surface of the work space, and an outside portion of the cabinet so as to exhaust the air flowing into the work space. Pass boxes connected to the clean booths are provided to a portion of the side surfaces of the work space. Each of the pass boxes is formed by a pass box coupling inner surface, the outside of which has a space formed by a pass box coupling outer surface. The space communicates with the circulation path. The bottom of the pass box coupling outer surface is provided with a pass box coupling outer surface slit.

摘要： Provided are a fan filter unit and a sterilization apparatus capable of shortening a sterilization operation time to be performed at a changeover. The sterilization apparatus has: a working space; a fan filter unit for supplying clean air to the working space; and a sterilizing gas charging unit on the air suction side of the fan filter unit. The fan filter unit comprises: a fan unit section constituted by an air blower and a pressurization chamber; a dust removal filter provided on the downstream side of the fan unit section; a passage bypassing the dust removal filter; and an opening and closing mechanism of the passage. By opening the opening and closing mechanism, the air flow not passing through the dust removal filter can be supplied to the secondary side of the fan filter unit.

摘要： In a state where an operator performs operation using a safety cabinet while confirming standard operating procedures and sample data, a display device such as a monitor screen provided in the safety cabinet is arranged at a position that is not subject to effects of deterioration due to diffused reflection of light from a fluorescent lamp or sterilization lamp irradiation, and that does not generate resistance in an airflow path, while also protecting the display device from decontamination operation and preventing dirt from being adhered to a portion related to display. Transparent windows are provided on both a portion of a back wall or a side wall of a work space in the safety cabinet and a portion of a rear wall or a side wall of the body of the safety cabinet separated from the back wall or the side wall of the work space by a circulation flow path, which allow the operator to see through both walls, and the display device is placed on an outer side portion of the transparent window provided at the portion of the rear wall or the side wall of the body of the safety cabinet.
