AW Pax +pat+ Connection ½ x ½ : Surface-Mounted Shower Fittings

Reference: A69340-001-008 | Finish: Chromeline | SSIGE Certified & SIA 181 Compliant

The AW Pax module is a high-precision patented mini-cartridge developed by AW AG engineers to effectively remedy hydraulic malfunctions such as excessive pressure and noise. This compact solution offers a modern, aesthetic alternative to the cumbersome and impractical traditional anti-hammer devices.

Acoustic Expertise & SIA 181 Standard

Sound control is a core feature of the AW Pax design, making it essential for meeting the "increased requirements according to SIA 181" (Sound insulation in building construction) in Switzerland.

• Certified Performance: The module reduces flow noise by up to 5 dB(A).
• SSIGE Measurement (ISO 3822): Laboratory tests specifically for this model show that a shower mixer's noise level at 0.5 MPa drops from 24.2 dB(A) to just 17 dB(A) when equipped with the Pax damper.
• Noise Group I Achievement: By reaching a level of 17 dB(A), the installation satisfies the criteria for Noise Group I (≤ 20 dB), even if the original fitting belonged to a less efficient category.

System Safety & Mechanical Protection

The AW Pax acts as an active shield, absorbing kinetic energy to protect the entire sanitary network from damage.

• Pressure Surge Control: It absorbs and reduces pressure surges by up to 25 bar. Without this protection, quick-closing valves can generate spikes exceeding 30 bar, leading to massive noise or even water damage.
• Equipment Longevity: The damper prevents fatigue failure in pipes and protects delicate internal components, such as ceramic cartridges, from abrupt pressure shocks.
• Structural Stability: Eliminates vibrations that could compromise the integrity of the plumbing system over time.

Technical Specifications & Installation

For total effectiveness, the following installation parameters must be strictly followed:

• Dimensions: Connection G ½" x ½" with a union nut (écrou mobile) for easier mounting.
• Required Projection: The product requires a specific projection of L = 53 mm, which must be strictly observed during installation.
• Expert Recommendation: For shower mixers with two inlets (hot and cold water), the dampers must be applied in pairs to ensure total protection for both lines.
• Operating Conditions: Nominal pressure PN 10 bar, maximum dynamic operating pressure 5 bar, and temperature resistance up to 80°C.

Technical Note: This high-precision device is the result of Swiss engineering, offering discreet and powerful protection for your sanitary installations.
