High quality manual backwash filters

permaster black

The permaster black backwash filter effectively prevents the ingress of dirt and – thanks to its optimized design – is now even more comfortable. The new black-tinted filter cup not only impresses with its particularly elegant appearance, but also offers additional protection against light and algae formation. The transparent cup also allows you to see at any time when the filter needs to be backwashed. According to DIN EN 806-5, the filter must be backwashed every six months at the latest. This can be done easily and practically in the blink of an eye. By turning the drain funnel, the patented belt brushes clean the stainless steel filter and the filter cup without interrupting the water supply. There is no need to replace the filter element.
