PP-HT AS Plus tee 110x110/87 IR (Internal Radial - gentle introduction), sanitary, for low-noise internal drainage, grey color 3079980

Low-noise tee for internal drainage

This PP-HT AS Plus 110x110/87 IR tee is a key element of an internal drainage system, designed for facilities where noise reduction is a priority. It is ideal for residential buildings, office buildings, hospitals, laboratories, and libraries – anywhere where acoustic comfort is important. The 87-degree angle provides an optimal connection for pipes at an angle, and the special Interial Radial (IR) design gently introduces flow, minimizing turbulence and noise.

Features and application

The tee made of polypropylene (PP) is characterized by high resistance to corrosion and mechanical damage. The AS+ system is distinguished by an exceptionally low noise level – the material sound index Lsc, A is only 10 dB for a flow rate of 4 l/s (according to EN-14366). This makes the installation quiet and comfortable for users. The tee is sanitary, which means it is suitable for draining sanitary sewage. Its gray color makes it easy to identify in the installation.

Advantages for installers and users

• Easy installation: Self-lubricating blue gasket eliminates the need for additional lubricants.
• Quick connection: Sculpted socket end reduces the force required for insertion by 50% compared to the standard AS system.
• Precise adjustment: Angle markings allow for precise adjustment of the tee position during angled installation.
• High-quality material: Polypropylene PP-HT ensures durability and resistance to sewage and temperatures up to 90°C (continuous flow) and 95°C (brief flow).
• Low noise level: Thanks to its unique design and material, the AS+ system effectively dampens the sounds of flowing wastewater.
• Compliance with standards: The product has a DVGW quality mark for water, confirming its safety and reliability.
• Tightness: The use of ethylene-propylene-diene monomer (EDPM) rubber gaskets guarantees a tight connection.

This tee is characterized by a nominal connection diameter of 1 and 3 of DN 100, an external pipe diameter of 1 and 3 equal to 110 mm, and an angle of 87 degrees. The maximum working pressure at 20°C is 0.5 bar, and the ring stiffness class is SN4.

The PP-HT AS Plus tee is an investment in comfort and peace of mind – both for installers who appreciate ease of installation and for users expecting a quiet and reliable drainage system.
