Flow regulators are real water savers. With flow regulators for retrofitting in existing products, you can reduce the water consumption of your shower by up to 40 %, for example – and saving on hot water also means saving on energy heating it.

Retrofit solution for shower handles – with dual mode

The ECOBOOSTER Shower is a dual mode flow regulator that is screwed between the shower handle and hose. It is set to water saving mode in its default position, with a flow rate of approx. 5 liters per minute, and can be very simply switched at the press of a button to the full flow rate (max. 20 liters per minute) if needed, such as for washing hair. This means that you can always choose between an economical or a greater amount of water. When the faucet is closed, the ECOBOOSTER Shower automatically switches back to water-saving mode.
