Flange Filter with Magnet - Series 11.000 M - DN 125; L=400mm BRA.11.000 M

Product detailed description

Flange filters with magnets are essential components in heating, ventilation and air conditioning (HVAC) systems, water distribution networks, and pumping stations. These devices protect downstream equipment from particulate contamination and ferromagnetic debris. Installers and technicians commonly encounter them in central heating systems, commercial buildings, and industrial facilities where fluid purity is critical. The device is mounted between flanges in accordance with EN 1092-1 standards, ensuring a secure and leak-free connection.

The filter is designed for use in closed-loop systems operating within a temperature range of -10°C to +100°C. It is suitable for water-based systems containing up to 50% glycol. However, it is not recommended for steam, gases, or fluids containing oils or hydrocarbons. The magnetic element ensures the removal of fine metallic particles that could otherwise damage sensitive components such as pumps and valves.

The nominal diameter (DN 125) determines the flow capacity and compatibility with piping systems. The pressure rating (PN 16) indicates the maximum allowable working pressure. These values are essential for correct system design and component selection. The material composition also influences performance, particularly in corrosive environments or high-temperature applications.

Installation and connection

To install the filter, ensure the flanges on either side are clean and undamaged. Align the filter body with the flange holes and secure using appropriate bolts and nuts. Check that the EPDM gasket is correctly seated to prevent leaks. Avoid over-tightening the bolts, which can cause flange deformation or gasket failure. Common installation errors include misalignment of the flange faces and incorrect torque applied to the fasteners. Always verify the system pressure and temperature limits after installation to ensure safe operation.

Compatibility and accessories

This filter is compatible with standard HVAC and water distribution systems using flanged connections. It is typically used in conjunction with pumps, valves, and heat exchangers. For optimal performance, ensure that the upstream piping is free of sharp bends or restrictions that could increase turbulence and particle deposition. No additional accessories are required unless specified by the system designer.

Technical background for designers

The filter operates by capturing solid particles in the stainless steel mesh while the magnetic element attracts ferrous contaminants. The cast iron body provides structural strength and thermal stability, while the EPDM seal ensures a tight closure. The screen aperture size varies between 0.8 mm and 1.6 mm depending on the model. This filtration capacity helps maintain system efficiency and reduces wear on downstream components. The design allows for easy disassembly and cleaning without interrupting the entire system flow.

Service and operation

Periodic inspection and cleaning are necessary to maintain filter performance. Remove the cover and clean the screen using a soft brush or compressed air. Check the EPDM seal for signs of wear or deformation and replace if necessary. Ensure the magnetic element remains securely attached and free from debris. Reassemble the unit carefully, ensuring all components are properly aligned and tightened.

Frequently asked questions

Can the filter be used in glycol-based systems?
Yes, the filter is suitable for water with up to 50% glycol content. However, it is not recommended for systems containing oils or hydrocarbons.

Is the filter suitable for steam applications?
No, the filter is not designed for steam or gas systems. It is intended for liquid applications only.

What is the maximum operating temperature?
The filter can operate continuously at temperatures up to +100°C. It is not suitable for higher temperatures.

Can the filter be installed in vertical piping?
Yes, the filter can be installed in both horizontal and vertical orientations. Ensure that the flange alignment and sealing are correct regardless of orientation.
