For use in indoor drainage systems for the discharge of domestic wastewater under gravity flow (where the leak test is performed at max. 0.5 bar), specifically where sound attenuation of water discharge is desired.
Reference standard: EN 1451.
They are black, mass-colored, single-layer, and made from PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
Socket and gasket jointing system; no special tools, adhesives, or solvents are required.
Acoustic performance is 16 dB for a flow rate of 2 l/s. The sound-absorbing properties are certified following 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. When passing through ceilings, we recommend using fire collars as a protective measure against flame propagation.
To reduce the noise level of indoor drainage systems, we recommend:
• Selecting a system of pipes and fittings with good sound-absorbing properties;
• Ensuring correct system design;
• Installing the system correctly using appropriate products.
