Try aerators to better regulate your shower and tap flow!

Aerators (flow regulator) are simple vacuum valves with an air intake that can be easily installed between the tap and hose, or between the hose and shower head.

Retrofitted to taps, the aerator – with or without flow regulators – can reduce the flow rate whilst generating less splashing to achieve better perceived ‘wet effect’ and efficiency.

The device introduces air into a pressurised water flow that expands when exiting the valve to create the feeling of higher flow rate. They may be combined with regulator valves that adjust flow space in response to pressure, ensuring a consistent set flow rate.

Result

Retrofitting an aerator will save you up to 6 litres of water per minute, which corresponds to a 50 % reduction compared to traditional installations.

Aerators are universal and can be installed anywhere providing the pressure of the water system is at least one bar.
