This product is utilized in indoor drainage systems for the discharge of domestic wastewater under gravity flow conditions (where the leak test is performed at a maximum of 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
These fittings are black, mass-colored, single-layer, and manufactured from PP with added minerals.
The size range includes diameters from 32 mm to 160 mm.
The connection system uses a socket and gasket, eliminating the need for special tools, adhesives, or solvents.
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 laboratories in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
The fire behavior classification, in accordance with DIN 4102-1, falls under class B1. For passages through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of indoor drainage systems, the following are recommended:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct design of the installations;
• Correctly installing the system using appropriate products.
