FAQ – AW Pax Shock Absorbers

What is water hammer?

Water hammer is a sudden pressure surge in the pipework, often caused by the rapid closure of a valve or tap. It produces a sharp banging noise and can damage the plumbing if no anti-shock device is installed.

How does an AW Pax shock absorber work?

An AW Pax shock absorber absorbs hydraulic shocks at source via a patented internal system. It limits pressure fluctuations, reduces pipe vibrations and decreases noise levels by up to -5 dB(A), thereby improving comfort in sanitary installations.

Are AW Pax shock absorbers compliant with the SIA 181 standard?

Yes. AW Pax shock absorbers are designed in accordance with the requirements of the Swiss SIA 181 acoustic protection standard. They help limit pipe noise and ensure a higher quality of use in residential and professional buildings.
