Anesthetic Gas Scavenging Systems The ULTRASEG® plant is an active system for suction of anaesthetic gases from operating theatres. The removal of these gases is essential as exposure to anaesthetic gases, in the long term, is a health risk to the work teams. ULTRASEG® is equipped with the latest generation of side channel vacuum pumps from the prestigious German brand and world leader, Elmo-Rietschle. The ULTRASEG® suction system is prepared and ready to be connected to an anaesthetic gases scavenging network which contains anaesthetic gases outlets, generally installed next to the point of use.
