Magnetic compact boiler filter CALEFFI 3/4" (model 545020)

Magnetic compact boiler filter CALEFFI 3/4" (model 545020) is a compact magnetic separator designed for central heating systems. It captures ferrous particles and sludge from the system water to reduce wear on boilers, heat exchangers and circulation pumps. The unit is intended for installation in return or feed lines of residential and light commercial heating circuits where space is limited and a reliable magnetic filtration solution is required.

Advantages

The compact body combines mechanical separation with a strong internal magnet to collect iron oxide and ferrous debris while maintaining a low pressure drop. Its 3/4" connections allow straightforward integration with common pipework; the construction is aimed at simplifying installation and routine maintenance. The design reduces the frequency of pump and boiler servicing by limiting abrasive particles in the hydraulic circuit.

Suitable for

• Residential central heating systems
• Light commercial heating circuits
• Installation on return or feed lines where space is limited
• Systems requiring protection of boilers, heat exchangers and pumps from ferrous debris

Key specifications

• Connection size: 3/4"
• Function: magnetic separation of ferrous particles and mechanical sludge capture
• Application: central heating systems, return or feed line installation
• Compact form factor suitable for tight installation spaces
• Material: corrosion-resistant housing with internal magnetic element (manufacturer materials)

How to use

Install the magnetic compact boiler filter in the chosen section of the heating circuit according to hydraulic flow direction, typically on the return or feed line. Ensure system pressure is isolated and cooled before beginning installation. Connect using appropriate 3/4" fittings and sealants compatible with the piping. After mounting, open the system and check for leaks; verify correct flow and system pressure. Periodically inspect and clean the collector and magnetic element following the manufacturer's maintenance intervals to maintain filtration performance.

Usage recommendations

For reliable operation, flush the system if heavy contamination is suspected before installing the filter. Schedule regular inspections and cleaning according to operating hours and water quality; in hard or heavily corroded systems more frequent maintenance may be required. Use compatible sealing materials and follow local regulations for heating system maintenance and safety.
