Aerator Ostendorf DN 110 domestic sewerage

The Ostendorf DN 110 vacuum valve (aerator) is designed to regulate air pressure in domestic sewerage systems and prevent unpleasant odors and harmful gases from entering indoor spaces through sewer pipes. The 110 mm aerator is designed for installation at the top of vertical sewer risers. It can be installed in attics, toilets, and bathrooms, allowing air to enter the sewerage system freely.
