This product is used in indoor drainage systems for the discharge of domestic wastewater under gravity flow conditions (where the leak test is performed at max. 0.5 bar), specifically where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, and made of PP with mineral additives.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
The size range includes diameters from 40 mm to 110 mm.
Acoustic performance is 16 dB for a flow rate of 2 L\/s. The sound-absorbing properties are certified following measurements conducted in the laboratories of the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
To reduce the noise level of indoor drainage systems, we recommend:
\u2022 Selecting a system of pipes and fittings with good sound-absorbing properties;
\u2022 Ensuring correct system design;
\u2022 Correct installation of the system using appropriate products. <\/p>\n","protected":false},"excerpt":{"rendered":"
