A device (1) for filtering a fluid circulating in a plumbing and heating system, said device (1) comprising:
- a body (2) of the device which defines therewithin a filtration chamber (3) that is destined to have a fluid to be subjected to filtration pass through the filtration chamber (3), said body (2) being provided with:
- an inlet/outlet interface (10) configured to allow an entry and an exit of the fluid into and from said filtration chamber (3);
- filtering members (40) that are at least partially housed inside said filtration chamber (3), or connected with said body (2) of the device, and configured to carry out filtering of the fluid passing through the filtration chamber (3), wherein said filtering members comprise at least one filtering element (41) configured to perform a mechanical separation of substances and solid particles present in the fluid to be treated from the fluid in which the substances and solid particles are suspended, said filtering element (41) being arranged inside said filtration chamber (3) so as to divide the filtration chamber into a first half-chamber (8) and a second half-chamber (9), and in such a manner that the fluid transiting in the filtration chamber (3) passes through said filtering element (41) in order to pass from said first half-chamber (8) to said second half-chamber (9), or vice versa;
- a first inlet/outlet opening (11), defined on a portion of said inlet/outlet interface (10), which sets said first half-chamber (8) in communication with an outside of the body (2) and is configured to receive fluid entering said body or to send fluid exiting from said body;
- a second inlet/outlet opening (12), defined on a respective portion of said inlet/outlet interface (10) and distinct and separate from said first inlet/outlet opening (11), which sets said second half-chamber (9) in communication with the outside of the body (2) and is configured to send fluid exiting from said body or receive fluid entering said body;
- and wherein:
- the first half-chamber (8) is in fluid communication with the first inlet/outlet opening (11), without passage through the filtering element (41);
- the second half-chamber (9) is in fluid communication with the second inlet/outlet opening (12), without passage through the filtering element (41);
- a connection module (30) mountable on said body of the device, and comprising:
- a first inlet/outlet conduit (31), configured to be connected with a pipe of a heating system in order to receive therefrom, or send thereto, fluid entering or exiting from said device;
- a second inlet/outlet conduit (32), configured to be connected with a respective pipe of a heating system to send thereto, or receive therefrom, fluid exiting from or entering said device;
- a connection interface (33) selectively connected with said inlet/outlet interface (10) of the body (2) of the device;
- a first passage section (34), defined on a portion of said connection interface (33), in fluid communication with said first inlet/outlet conduit (31);
- a second passage section (35), defined on a respective portion of said connection interface (33) and distinct and separate from the first passage section (34), in fluid communication with said second inlet/outlet conduit (32),
- wherein the connection module (30) is configured to be selectively mounted on the body (2) of the device according to a plurality of different operative configurations:
- wherein the inlet/outlet interface (10) has a flat circular form and extends circularly around an interface axis (16), and wherein the connection interface (33) has a flat circular form and extends circularly around a respective central axis (36), and wherein, under conditions of assembly of the device, and in each of said operative configurations, the central axis (36) coincides with said interface axis (16) of the inlet/outlet interface (10);
- wherein the first passage section (34) occupies an angular portion of the connection interface (33), relative to said central axis (36), and the second passage section (35) occupies a respective angular portion of the connection interface (33), relative to said central axis (36), separate and distinct from the portion occupied by the first passage section;
- wherein the angular portion occupied by the first passage section (34) corresponds to a circular sector of the connection interface (33), and the respective angular portion occupied by the second passage section (35) corresponds to a respective circular sector of the connection interface which is diametrically opposite the circular sector of the first passage section (34), and wherein a separation zone (37) occupies a remaining part of the connection interface (33) that is not occupied by the first (34) and the second passage section (35).
