## Summary description

CALEFFI Dirtmag is a dirt separator with an integrated magnet designed for hydronic systems. This 3/4" inline unit (model 545305) removes particulate contaminants and captures ferrous particles via the magnet to protect boilers, pumps and valves. It is intended for installation on heating and chilled-water circuits to reduce maintenance and prolong component life.

## Long description

CALEFFI Dirtmag dirt separator with magnet 3/4" is an inline device engineered for hydronic heating and chilled-water systems. The unit separates suspended particulate matter from the circulating fluid and captures ferrous debris using an integrated magnet, helping to reduce wear on boilers, pumps, valves and heat exchangers. Designed for in-line installation on return lines or bypass circuits, the compact 3/4" body enables straightforward integration into residential and light-commercial installations where protection against sludge and metallic particles is required.
Advantages
The Dirtmag combines mechanical separation and magnetic capture in a single compact body, providing continuous protection without electrical power. Its internal geometry directs flow to promote sedimentation while the permanent magnet retains ferrous particles, reducing the frequency of system flushing and component replacement. The unit’s brass construction and serviceable sediment collection chamber make maintenance simple and reliable, while the 3/4" format preserves flow characteristics suitable for small to medium circuits.
Suitable for
Domestic and small commercial hydronic heating systems
Chilled-water circuits in light-commercial applications
Return lines to protect boilers, pumps and control valves
Systems requiring protection from both non‑magnetic sludge and ferrous debris
Key specifications
Connection size: 3/4" inline configuration compatible with standard pipe fittings
Function: combined mechanical dirt separation and magnetic particle capture
Materials: corrosion-resistant brass body with permanent magnet element and removable sediment chamber
Installation orientation: in-line, typically on the system return side
Maintenance: removable collection chamber for periodic cleaning without system disassembly
How to use
Install the Dirtmag in the system where return flow is accessible and where gravity-assisted sedimentation is possible, following hydraulic flow direction markings on the body. Securely connect the 3/4" fittings and ensure the unit is supported to avoid pipe stress. Periodically isolate the unit and drain the sediment chamber to remove accumulated debris; magnetic particles adhere to the magnet and should be wiped clean during service intervals. Follow local plumbing codes and the system manufacturer’s instructions when selecting installation location and isolation valves.
Usage recommendations
For optimal performance, fit isolation valves upstream and downstream to allow safe removal and cleaning without emptying the entire system. Schedule regular inspections—frequency depends on system cleanliness and water treatment—and combine use of the Dirtmag with appropriate filtration and chemical treatment to address both particulate and corrosion-related issues.
