FILTRATION
Filtration is achieved through a cylindrical screen. As soon as the filter is clogged, a pressure switch detects the pressure difference between inlet and outlet and starts the cleaning cycle.

CLEANING
The cleaning cycle is performed by the means of a suction arm which rotates and backwashes the filter screen surface. The cleaning effect is focused on the suction arm holes. A complete rotation of the suction arm is achieved, so that the whole surface is cleaned in one cleaning cycle.
