The filter is used to remove the impurities present in the recirculation water of domestic and condominium systems

The filter can be also used to add chemical products to the recirculating water to protect the plant


The filter is made with a series of layers of sand with variable granulometry. The heating system water is deflected through the filter in a calibrated percentage (usually around 10% of the total flow). In this way the layers of sand retain the impurities and progressively eliminate the impurities present. The filter has an integrated hydraulic system which allows the water to flow in the opposite direction compared to the operation way. Thus, with short-term washings, it is possible to clean the filtering layers in a to restore filtering efficiency to the masses of sand which tend to become progressively clogged with use.
