Abstract
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.
Claims6
A biosafety cabinet comprising:
- a work space formed on an inner surface side of a front shutter;
- a circulation passage formed from a lower surface side, a lateral surface side and a rear surface side of the work space, and an outer part of the biosafety cabinet for discharging air having flown into the work space, and
- an air supplier disposed on an upper surface of the work space for supplying air to the work space, characterized in that
- an ionizer is provided right above an airflow branch point where the air supplied to the work space branches toward a front surface and a rear surface of the biosafety cabinet.
