Anaesthetic Gas Scavenging System (AGSS)

Flow-through exhaust device: The waste anesthetic gas from the operating room is exhausted to the  outside through this device. Its basic principle is to use the positive pressure in the operating room and  the positive pressure of compressed air to create a relative negative pressure area that carries away the  waste gas 

Positive pressure power source: The positive pressure power source is provided by the compressed air  in the operating room

Generally, operating rooms are equipped with compressed air for common use. Technical requirements:  The pressure should be controlled not lower than 0.5Mpa, with a pipe diameter of 4mm 

Filter: An air filter should be installed in the pipeline, with a filtration efficiency of 99.99%, and generally  replaced every six months

The design of the exhaust port at the end of the pipeline should be in line with the wind direction to  prevent backflow of air; the exhaust port should be equipped with a wire mesh to prevent dust and  insects from entering and causing blockages
