Replacement Filter Insert for Series BRA.11.000 and BRA.11.000 M - DN 125 BRA.11.000 FV

Product detailed description

Filter inserts are essential components in industrial and commercial fluid systems where particulate removal is required to protect downstream equipment. In HVAC systems, water supply networks and pumping stations, these filters help prevent clogging of valves, pumps and heat exchangers. Installers working on such systems often encounter situations where a filter element needs replacing due to wear or blockage. This particular filter insert is designed for integration into flanged connections in accordance with EN 1092-1 standards, ensuring compatibility with existing infrastructure.

Its application range includes systems operating within a temperature range of -10°C to +100°C and using water with up to 50% glycol content. It is not recommended for steam, gases or hydrocarbon-based liquids. The design allows for easy cleaning via a bleed screw, which aids in removing trapped debris during maintenance.

The technical parameters define the filter’s compatibility with specific system conditions. The body and cover are made of cast iron GJL 250, providing robustness under mechanical stress. The mesh is constructed from AISI 304 stainless steel, which resists corrosion in water environments. The EPDM sealing ensures a leak-free connection. These parameters are essential for selecting the correct filter insert for a given system configuration and media type.

Installation and connection

To install the filter insert, align the flange faces and ensure the EPDM gasket is correctly positioned between them. Secure the connection using PN16-rated bolts according to EN 1092-1 specifications. Verify the alignment of the bleed screw to allow access for future cleaning. A common mistake is misalignment of the flange faces, which can cause leakage or uneven pressure distribution. Always check for proper seating of the sealing surface before tightening the bolts fully.

Compatibility and accessories

This filter insert is specifically designed for use with the IVAR series BRA.11.000 and BRA.11.000 M. It requires compatible flanged connections and must be installed in systems that operate within the specified temperature and media limits. No additional accessories are required for standard installation. Ensure the system is drained and depressurised before replacing the filter element to avoid injury or damage.

Technical background for designers

The filter operates by allowing fluid to pass through the stainless steel mesh while trapping larger particles. The mesh aperture varies depending on the size, typically between 0.8 mm and 1.6 mm, ensuring effective filtration for general applications. The cast iron body provides structural integrity and resistance to thermal expansion. The choice of EPDM sealing ensures compatibility with glycol-based fluids and prevents chemical degradation over time. The design allows for integration into both new and existing systems with minimal modification.

Service and operation

Periodic inspection is recommended to ensure the filter remains free from blockage. The bleed screw enables manual removal of trapped particles without disassembling the entire unit. During operation, monitor for signs of pressure drop across the filter, which may indicate the need for cleaning. No specific service intervals are provided in the technical data, but regular visual checks are advised in high-use environments.
