Technicalia - Model ø110 -Passive Chimney Filter

A passive chimney filter is a device used to remove odors in facilities that are part of the sanitary sewage infrastructure. Chimney filters are most often used in sewage pumping stations, as the frequently changing sewage levels in the pumping station pits cause air to escape into the atmosphere, which can cause unpleasant odors in the surrounding area. The neutralizer is equipped with an activated carbon cartridge through which air flows and is purified. The device is a passive neutralizer, meaning it does not have an electric fan. Air flow is forced by gravity – either through the pressure difference inside and outside the pit or by sewage flowing into the facility, displacing air from the sewers, pumping stations, or pits.
