Filter for the Treatment of a Fluid in a Heating and/or Cooling System

A filter for treating a fluid in a heating and/or cooling system, in particular of domestic and/or industrial type, said filter comprising:

• a first body, hollow and substantially cylindrical in shape, and a second body, wherein said first body and second body are mutually and sealingly connected, so as to internally comprise a chamber, and wherein said hollow first body is provided with a first mouth and a second mouth respectively comprising a first duct and a second duct allowing the fluid to enter and/or exit the chamber,
• a filtering element for treating the fluid and housed at least partially in said chamber,
• a shut-off element comprising an outer wall provided with a channel and an opening, said shut-off element being housed in the first body in a manner such that it can rotate about a longitudinal axis in said first body and alternately switch:
• from a first position, in which said shut-off element is positioned in such a way as to allow the flow of fluid to enter the chamber via the communication of the first duct with the channel and to exit the chamber via the communication of the opening with the second duct;
• to a second position, in which said shut-off element is positioned in such a way that an outer wall thereof obstructs the first duct and prevents the flow of fluid from entering the chamber.
