In a positive pressure cleanroom, filtered air is consistently pumped into the room through theHEPA filtrationandcleanroom HVAC system. If a door or window were opened in the cleanroom, air would rush out into the outside environment. This positive pressure ensures that the products and processe...
In most cases, glove boxes are kept at a positive pressure difference, also known as overpressure. You only need the internal chamber environment to be a few mbar overpressure to create a positive pressure glove box. At overpressure, the gloves will stand erect from the box. If there are an...
