This product is used in internal drainage systems for the discharge of domestic wastewater under gravity flow (leak test up to 0.5 bar), specifically where sound attenuation of water discharge is desired.
Reference standard: EN 1451.
These are black, mass-colored, single-layer products made of PP with mineral additives.
The size range includes diameters from 32 mm to 160 mm.
The socket and gasket jointing system requires no special tools, adhesives, or solvents.
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 in Germany, in accordance with EN 14366. The use of sound-absorbing clamps is recommended.
Fire behavior classification, in accordance with DIN 4102-1, falls under class B1. For passages through ceilings, we recommend using fire-resistant clamps as a protective measure against flame propagation.
To reduce the noise level of internal 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.
