This fitting is used in indoor sewage systems for the discharge of domestic wastewater under gravity flow conditions (where the leak test is performed at max. 0.5 bar), particularly where sound dampening from water discharge is desired.
Reference Standard: EN 1451.
These fittings are black, mass-colored, single-layer, and made of PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Featuring a socket and gasket joint system, no special tools, adhesives, or solvents are required for installation.
The acoustic performance is 16 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified by measurements conducted at the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing pipe clamps is recommended.
The fire behavior classification, in accordance with DIN 4102-1, is B1. When passing through ceilings, we recommend using fire collars as a measure to prevent flame propagation.
To reduce the noise level of indoor sewage systems, the following are recommended:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correct installation of the system using appropriate products.
