AW Pax +pat+ Connection: Surface-Mounted Fittings (Shower & Bath)

Reference: A69339-001-008 | Finish: Chromeline | SSIGE Certified & SIA 181 Compliant

The AW Pax connection is a patented high-precision mini-cartridge developed to remedy hydraulic malfunctions in surface-mounted shower and bathtub fittings. This compact solution offers a modern and efficient alternative to bulky traditional damping devices, ensuring a seamless integration with your fixtures.

Acoustic Expertise & SIA 181 Standard

Superior sound control is a hallmark of the AW Pax design, ensuring that plumbing noise does not disrupt the peace and quiet of the home.

• Regulatory Compliance: Designed to support compliance with the strictest building acoustics standards (SIA 181) in Switzerland, which are essential in modern residential construction.
• Acoustic Performance: The module effectively reduces flow noise by up to 5 dB(A), significantly lowering the sound transmitted to adjacent living spaces.
• Residential Quality: Helps maintain a quiet environment by dampening the vibrations caused by high-velocity water flow through the valves.

Mechanical Protection & System Safety

The AW Pax acts as an active shield, absorbing kinetic energy to protect the entire sanitary network from the destructive force of water hammer.

• Pressure Surge Control: It provides active control by reducing pressure surges by up to 25 bar. Without this protection, quick-closing valves can generate peaks exceeding 30 bar.
• Damage Prevention: Prevents the harmful effects of water hammer, such as loud pipe banging, structural vibrations, and potential pipe bursts.
• Component Longevity: Protects delicate internal parts of the mixers and shower valves from abrupt pressure shocks, extending the service life of the equipment.

Technical Specifications

To ensure total effectiveness and a secure fit, the following technical parameters must be strictly followed during installation:

• Connection: Standard ¾" x ½" with a union nut (écrou mobile) for easy and secure attachment to surface-mounted fittings.
• Required Projection: A specific projection (length) of L = 53 mm is required and must be strictly observed during installation to ensure proper function.
• Expert Recommendation: Must be applied in pairs (one for hot water and one for cold water) to ensure full protection for both lines of the mixer.
• Operating Conditions: Nominal pressure PN 10 bar, maximum dynamic pressure 5 bar, and temperature resistance up to 80°C.

Technical Note: This high-precision device is a product of Swiss engineering, providing discreet and powerful protection for high-quality shower and bath installations.
