Description
The first stage is achieved with self-cleaning pre-filter Hydra type, with SX (DOE) cartridges with choice between RAH (stainless steel net), RLH (polyester net) and RSH (pleated polypropylene fabric).
During this phase, thanks to the counter-current washing, collected impurities are removed from the external surface of the cartridge and they are eliminated using the specific drain equipped with anti-reflux system.
In the second stage it is possible to house both cartridges from the SX (DOE) and the BX (SOE – o-ring 222) series; the filtration sequence and/or treatment can therefore be customised according to specific requirements.
The IN/OUT connections available are 1/2”, 3/4”, 1” with brass or plastic thread BSP, or plastic with NPT thread 3/4” and 1”.
The Hydra DUO self-cleaning water filters are tested and certified respecting the most stringent international standards in order to guarantee all of the quality and safety required by the sector.
