Dirt separator with magnet CALEFFI DIRTMAG 1" composite - model 545306

CALEFFI DIRTMAG 1" composite model 545306 is a dirt separator with an integrated magnet designed for hydronic heating and cooling systems. Constructed in composite material, this inline device removes suspended particulate debris while the internal magnet captures ferrous particles. The unit is intended for domestic and light-commercial installations where protection of pumps, valves and heat exchangers from abrasive and magnetic contamination helps maintain system efficiency and reduce unscheduled maintenance.

Advantages

The composite body provides corrosion resistance and reduced weight compared with metal alternatives while maintaining structural stability for typical system pressures. The integrated magnet enhances removal of iron and steel particles that would otherwise circulate and abrade moving parts. The separator design promotes sediment collection in a removable chamber, enabling straightforward cleaning without system disassembly. Overall, the product contributes to improved component life and more consistent heat transfer in hydronic circuits.

Suitable for

• Domestic central heating systems
• Light-commercial hydronic heating and cooling installations
• System protection for pumps, circulation valves and heat exchangers
• Preventive maintenance programs to reduce downtime

Key specifications

• Connection size: 1" inline fitting suitable for standard piping
• Body material: composite for corrosion resistance and low weight
• Integrated magnetic element for ferrous particle capture
• Removable sediment chamber for periodic cleaning
• Designed for use in heating and cooling hydronic circuits

How to use

Install the DIRTMAG in the return line of the hydronic circuit following system flow direction to maximise sediment and magnetic particle capture. Securely tighten connections and ensure the unit is accessible for routine inspection. During operation, the separator collects suspended solids and the magnet attracts iron particles; periodically isolate the unit, depressurise the circuit according to local codes, and remove the sediment chamber to clean trapped debris and wipe the magnetic surface. After reassembly, check for leaks and restore normal system operation.

Usage recommendations

For reliable performance, place the dirt separator where gravity and flow conditions favour sedimentation, typically on the return side before pumps and heat exchangers. Establish a regular inspection and cleaning interval as part of preventive maintenance; frequency depends on system dirt load and water treatment. Use compatible sealing materials for composite connections and follow installer instructions to avoid over-tightening. If heavy contamination is present, combine the DIRTMAG with pre-filtration or flushing procedures to reduce initial debris levels.
