Caleffi Dirtmag Dirt Separator with Magnet 2 Inch NPT Female Connection - 546309A.

The Caleffi DIRTMAG magnetic dirt separator removes both ferrous and nonferrous impurities continuously, featuring powerful removable magnets that remove up to 100% of the ferrous impurities, including magnetite, that can form in a hydronic system. The Caleffi DIRTMAG has 2 1/2 times the removal performance of a standard dirt separator.

In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in the heat exchangers, heating elements and pipes, resulting in a lower thermal efficiency within the system.

The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing even the smallest particles, with extremely limited head loss.




The dirt separator operating principle is based on the combined action of a number of physical phenomena.

The internal element (1) is composed of a set of radial reticular surfaces. The impurities in the water, on striking these surfaces, get separated, dropping into the bottom of the body (2) where they are collected.

In addition, the large internal volume of Dirtmag slows down the flow speed of the medium thus helping, by gravity, to separate the particles it contains. The collected impurities are discharged, even with the system running, by opening the drain cock (3) with the key (4) provided.
