Bacteria filter Description / Place of application Bacteria filter In order to avoid contamination, the bacteria filter has to be installed between the injector or vacuum regulating unit and the secretion-collecting jar. Thanks to the special treatment of the case surface and the silicone sealings, the bacteria filter has a good chemical resistance Filter membrane The filter material is made of PTFE (Teflon ) with a pore size of 0.2 µm. Its permanent hydrophobe effect prevents humidity from getting into the evacuation equipment. Place the white filter membrane into the case and make sure that it is not folded or wrinkled. Disinfection and cleaning Before each application, the bacteria filter has to be autoclaved at 134°C. For evacuation purposes, the filter membrane has to be replaced or cleaned when the suction resistance rises notably, but after 3 days at the latest. When using the filter for inhalation purposes (filtration of dry gases), the filter membrane should be replaced or cleaned once a week. Each filter insert can be autoclaved up to 10 times. The adjusting ring can be used to mark the number of autoclavings per filter insert. For this purpose, place the adjusting ring into the position “1” after the first autoclaving. After each autoclaving process, the ring is placed into the next higher position until you have reached number “10“, which means that the filter insert has to be replaced.
