Drainage reduction for Silent-PP systems – quiet and efficient installation

This asymmetrical Silent-PP reduction by Geberit is a key element in internal drainage installations where noise reduction is a priority. Use in the Silent-PP system allows for the creation of a quiet and comfortable drainage installation, especially in residential and public buildings. The reduction design allows connecting pipes with diameters of 110 mm and 90 mm, ensuring smooth wastewater flow.

Design and application

The reduction made of polypropylene (PP-MD) is characterized by high durability and corrosion resistance. The asymmetrical shape and long construction affect the damping of sounds of flowing media. Designed for connecting elements with different diameters in internal drainage systems, the reduction finds application in:

• Residential buildings – apartments, single-family homes
• Public buildings – hotels, offices, schools
• Sanitary installations requiring noise reduction
• Modernization of existing drainage installations
