For use in internal drainage systems for domestic wastewater discharge in gravity flow mode (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, made of 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 by measurements conducted at the Fraunhofer Institute laboratories 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 the noise level of internal drainage systems, we recommend:
• Selecting a pipe and fitting system with good sound-absorbing properties;
• Ensuring correct system design;
• Installing the system correctly using appropriate products.
