The wound filters are GRP (fiberglass reinforced polyester) tanks intended to work at high internal pressures, performing filtering functions. In order for the tanks to withstand the test and working pressures, an extra fiberglass winding is applied to both the cylinder and the covers to give it the required resistance.
The design of the filters (calculations and materials) is based on the AD-Merkblatt-N1 and BS-4994 standards. They are also manufactured according to the European Directive for pressure tanks 97/23 / CE.
The choice of the filter bed will be made according to the treatment needed by the waters, as well as the incorporation of a filter self-cleaning system.
The available diameters are: 1400, 1600, 1800, 2000, 2200, 2350, 2500 and 3000 mm.
Working pressures: 2.5, 4 and 6 kg / cm2, the test pressure being 1.5 times higher than the working pressure.
Filtration speeds: 20, 30, 40 and 50 m3 / h / m2.
