PP-HT short reducer AS Plus 110x75 sanitary, for low-noise internal drainage, grey color 3080079

Reduction to internal drainage – quiet and effective

This PP-HT AS Plus 110x75 reduction is an element of a drainage system designed for buildings requiring high sound insulation. It is ideal for apartments, offices, hospitals, laboratories and libraries – anywhere where acoustic comfort is a priority. Made of polypropylene, it provides a durable and reliable connection of pipes with different diameters.

Design and application

The AS Plus reduction allows connecting a 110 mm diameter pipe with a 75 mm diameter pipe. Its design, based on the three-layer structure of AS+ pipes, significantly reduces both airborne and impact noise. The pipe core filled with minerals and plastomers increases the material density, which translates into better sound damping properties. Additionally, the eccentric shape of the reduction optimizes the flow and minimizes turbulence, which could generate additional noise.

Advantages for the installer and user

• Low noise level: The AS+ system is characterized by an exceptionally low noise level (Lsc, A = 10 dB for a flow rate of 4 l/s), which ensures user comfort.
• Easy installation: Self-lubricating blue gasket eliminates the need for additional lubricants. The sculpted end reduces the insertion force by half compared to the standard AS system.
• Precision: Angular markings facilitate precise positioning of the fitting at an angle to the main axis of the installation.
• Durability: Made of high-quality polypropylene (PP) resistant to temperatures up to 90°C (continuous flow) and 95°C (brief flow).
• Safety: DVGW quality mark confirms safety of use in water installations. Seals made of EPDM rubber ensure a tight connection.
• High-quality materials: Wall thickness of connection 1 is 5.3 mm and connection 2 - 3.5 mm, which guarantees the strength and durability of the element. Circumferential stiffness class SN4 ensures resistance to external loads.
• Compliance with standards: The system meets the requirements of EN-14366 standard regarding noise protection in drainage installations.

The AS Plus reduction is an investment in comfort and peace of mind – both for the installer who will appreciate the ease of installation, and for the user who will enjoy the quiet operation of the drainage system for years to come.
