Strainer filter with magnet FERRO F04M, angled mesh, union-union connection DN32 (G1 1/4)

FERRO F04M is an angled mesh strainer filter with an integrated magnet, designed for DN32 (G1 1/4) union-to-union connections. The device combines a fine stainless-steel mesh element and a strategically placed magnet to capture both mechanical debris and ferrous particles in closed and open water circuits. Intended for installation in heating, chilled water and industrial water systems, this strainer filter reduces the risk of damage to pumps, valves and heat exchangers by removing sediment and metallic contaminants before they circulate through the system.

Advantages

The angled body design facilitates compact installation and simple draining while maintaining flow efficiency. The mesh element traps sand, scale and other non-magnetic particles, and the integrated magnet retains iron and steel particles that can cause wear and blockages. Union-to-union threaded connections allow for quick removal and cleaning of the screen and magnet without disturbing adjacent piping. The construction materials and geometry are selected to ensure reliable separation performance and straightforward maintenance.

Suitable for

• Heating systems (central heating, radiators and boiler circuits)
• Chilled water and air conditioning circuits
• Industrial water supply and recirculation systems
• Protection of pumps, control valves and heat exchangers

Key specifications

• Connection type: union-to-union threaded connection, size DN32 (G1 1/4)
• Strainer form: angled body for compact installation
• Filtration medium: removable mesh screen for mechanical debris capture
• Magnetic separation: built-in magnet for ferrous particle retention
• Application fluids: heating water, chilled water, industrial water

How to use

Install the strainer filter in the pipeline according to flow direction markings, ensuring union connections are tightened to the manufacturer’s recommended torque. Position the angled body to allow access to the union nuts and drain point. During normal operation the mesh and magnet capture particles; periodic inspection and cleaning of the mesh and magnet are required to maintain flow and protection performance. To service, isolate the circuit, relieve pressure, unscrew unions and remove the mesh and magnet for cleaning. Reassemble and restore pressure after confirming all seals and connections are secure.

Usage recommendations

For reliable performance, perform routine inspections and clean the mesh and magnet at intervals determined by system contamination levels. Use compatible sealing materials on threaded unions and ensure the unit is installed upstream of sensitive equipment. Avoid strong acids or abrasive cleaners during maintenance; clean components with a mild detergent or water and remove adhered ferrous debris from the magnet with a non-metallic tool.
