Water filter for drinking water treatment in recreational vehicles.

Hengst offers a high quality two-stage filter system that makes clean drinking water available anywhere in the world. In cooperation with Grünbeck – a specialist for drinking water treatment – Hengst has developed a water filter that effectively filters out heavy metals, odors, turbidity and bacteria, in order to provide drinking water of the highest quality. The result of this development is a mobile filtration solution for recreational vehicles that can be adapted to virtually any drinking water tank in order to provide hygienic and pure water. The filter element comprises two innovative filter stages with activated carbon to filter out chlorine, for example, and an additional material to filter out pathogens and colloids.

Hengst chose the patented Energetic filter concept, an in-house development, for the system. The filter consists only of filter materials and plastic components, namely an end cap and an internal tube. This concept, combined with ultrasonic welding, eliminates the need for adhesives during production. The filter thus reliably meets almost all drinking water standards and is food compliant.

Another advantage of the system is that the filtration principle does not use a membrane as a separation system. The use of a special medium without a membrane enables high filtration quality with a very low differential pressure. This achieves an excellent water flow rate or volume flow even in the case of a low-capacity pump.
