Peculiar filtration requirements for waters designated to irrigation or micro-irrigation in agriculture need systems using quartzite layers.
Filtration takes places through the passage of water from the bottom to the upper thought the sand layer that is set in a double separate chamber.
Particles are gradually blocked till the below layer is reached and the filtering efficacy increases as the liquid goes downwards.

Basically it is the same natural process of water that goes through the ground layers before reaching the underground flap.

The substantial difference with respect to the vertical model Arena is the presence of the double filtration chamber that enables the single filter to filtrate in a continuous way, also during back washing that takes place in a chamber at a time.

Available in the following versions:

In the automatic versions the continuous operation is assured by valves automatism. The valves are controlled by a programmable control box.

Both filters and support-frame are completely made of painted or zinc-coated steel.

In the lower inside part of the chambers Dual Filters are equipped with filtering arms with 0,25 mm nozzles through which water flows outside perfectly filtered.
