Suction arm cleaning principle

Hectron automatic self-cleaning filters principle (AG Series) :

Filtration. Filtration is achieved through a cylindrical screen. As soon as the filter screen 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.

Drain. During the cleaning cycle, a solenoid valve is opened and the suspended solids are drained out of the filter.
