Abstract
A gas curtain device for a load port includes a casing, a holding unit, a gas-permeable plate, and a fastener unit. The casing defines an inner space and including a flange that defines a gas outlet in spatial communication with the inner space. The holding unit is disposed in the casing, and defines a ventilation opening. The plate is positioned between the holding unit and the inner flange, and has holes. A curtain-forming gas is introduced into the inner space, and sequentially flows through the ventilation opening and the holes to be discharged from the gas outlet to form a gas curtain. The fastener unit connects removably the holding unit and the plate to the flange.
