Hypoxic cleanroom system is provided for industrial applications. The equipment of the system provides clean low-oxygen or oxygen free environments with climate control and at normal atmospheric or increased pressure. The system employs an oxygen-extraction device, which supplies oxygen-depleted air inside an enclosure communicating with the device. The system may employ a gas-recycling feature by drawing oxygen-depleted gas mixture from the enclosure back into an intake of the oxygen-extraction device wherein it is mixed with an ambient air intaken by the device or by using additional oxygen-extraction device for gas recycling. For cleanroom applications the system employs a gas-recirculating device, which draws internal gas mixture from a cleanroom interior for cleaning and regulating its temperature and humidity, and sends it back through a perforated ceiling, producing laminar flow inside cleanroom. The system may be applied to interior space inside any structure. |
