Air-Powered™ Showers vs Aerated Showers

How Air-Powered™ is Superior

Kelda are the inventors of Air-Powered™ technology, developing showers that require less water and energy per shower event than conventional mixer showers. Our high-efficiency showers significantly reduce carbon emissions.

Air-Powered™ shower technology is the result of over a decade of research and development, drawing from advanced aerospace engineering.

Air-Powered™ showers offer users a superior shower experience using less water, operating at flow rates as low as 4.5 litres per minute but with an equivalent spray force of 9 litres per minute.

Aerated Explained

Conventional ‘aerating’ showers use the Venturi principle to restrict flow and draw atmospheric air into the water through a small hole in the shower head. This is a very cheap way to reduce the mass flow of water, and aerate it to change the ‘feel’ of the shower, but has no measurable boost in force or performance, regardless of flow rate.

The Future of Sustainable Showering

In contrast, Kelda’s patented Air-Powered™ showers use the principles of fuel injection technology. Each shower features an intelligent microprocessor and powerful digital fan which controls the delivery of water and air to the showerhead. Within the showerhead, water is injected into a high-velocity air stream where it is broken up into 100s of droplets that are 2.5X the size of a standard shower

Larger droplets yield larger momenta providing the sensation of more spray force, making less water feel like so much more. With 15X more impact than a standard shower, a Kelda shower is more effective at rinsing shampoo out of even the thickest of hair.

Our Air-Powered™ showers represent the future of sustainable showering. By injecting water into air, it marks the beginning of a new era of clean technology and unrivalled experience.

The sole objective has always been to make less water feel like so much more.

Due to Air-Powered™ showers creating significantly larger water droplets than aerated showers, their spray from retain warmth longer. This means that they are more effective when paired with waste water heat recovery systems.

Data collected has shown that users claim that Kelda showers are as good as, or better than, standard showers whilst using 50% less water, with 91% of women and 73% of men claiming so.
