Utilized in internal drainage systems for the discharge of domestic wastewater under gravity flow conditions (leak test performed at max. 0.5 bar), where sound attenuation from water discharge is desired.
Reference standard: EN 1451.
These 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. Sound-absorbing properties are certified by measurements conducted at the Fraunhofer Institute in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
Fire behavior classification, in accordance with DIN 4102-1, is B1. When passing through ceilings, we recommend using fire-resistant clamps as a protective measure against flame propagation.
To reduce noise levels in internal drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Correctly installing the system using appropriate products.
