It prevents siphon empty suction noises and sewer odours by using a rubber diaphragm that automatically opens under negative pressure and seals airtight otherwise. With a ventilation capacity of up to 87 l/min, it enables flexible pipe gradients and unlimited bends, simplifies installation, and enhances fire and smoke safety. Made from durable polypropylene and rubber, it resists mechanical, chemical, and thermal influences, ensuring long-lasting, maintenance-free operation. ## Description AlcaPlast APH sewage pipe aerator. Ventilation valve for HT pipes with corresponding pipe diameter. Pipe aerators prevent the empty suction of siphons (audible glucking) and at the same time the penetration of odour from the sewer pipe. A rubber membrane allows automatic opening of the pipe aerator in case of negative pressure (thus ventilation of the pipe) and automatic closing (due to the resulting pressure equalization in the pipe). This process is done automatically, e.g. when the toilet flush is operated or when using a sink. After the automatic closing of the pipe aerator, the pipe is sealed odour-tight and is only automatically opened again at negative pressure (water drain). The pipe ventilation gives you more flexibility when installing your water pipe: a ventilated pipe requires only 0.5% instead of 1% gradient. With connection lines, only 3 deflections are usually allowed, while with a ventilated pipeline, the number of bends is not limited. An elaborate ventilation line can also be dispensed with. When choosing the installation location, please note that the aerator is mounted at least 10 cm for connection lines and at least 60 cm above the highest branch or pipeline for downpipes. Easy to install, no unpleasant odour from the sewage pipes and sanitary facilities. Ventilation of the pipe system and the water drain works possible fire and smoke spread (chimney effect) in sewage pipes resistant to normal mechanical, chemical and thermal influences ## Features - AlcaPlast APH waste water pipe aerator ventilation valve for HT pipes with corresponding pipe diameter - Pipe aerators prevent the empty suction of siphons (audible glucking) and at the same time the penetration of odour from the sewer pipe.
