Replacement Filter Insert - for Series BRA.11.000 and BRA.11.000 M - DN 300 BRA.11.000 FV

Product detailed description

Flanged filters are essential components in HVAC and water distribution systems, where they prevent particulate matter from entering sensitive equipment such as pumps, valves and heat exchangers. This replacement filter insert is designed for use in larger pipe sizes, typically found in central heating systems, industrial water circuits and municipal pumping stations. Installers working in commercial buildings, industrial plants and large residential complexes often require these inserts for regular maintenance or replacement after clogging or wear. The filter is installed between flanges according to EN 1092-1 standards, ensuring a secure and leak-free connection in pressurised systems.

When selecting a replacement filter insert, it is important to ensure compatibility with the existing filter housing and system conditions. This insert is specifically engineered for the IVAR series BRA.11.000 and BRA.11.000 M models, making it suitable for applications involving water with up to 50% glycol content. It is not intended for use with steam, gases, or hydrocarbon-based liquids. The materials selected—cast iron for the body and lid, stainless steel for the screen, and EPDM for the gasket—ensure durability in environments with moderate temperatures and pressures.

The technical parameters define the operational limits and material composition of the filter insert. The maximum operating temperature is -10°C to +100°C, and the pressure ratings vary depending on the nominal diameter (DN). For DN 32 to DN 200, the maximum pressure is 16 bar, while for DN 250 to DN 350, it is 10 bar. These parameters are critical for proper sizing and selection to ensure the filter functions effectively within the hydraulic system. The material composition also plays a role in compatibility with the fluid being filtered and the mechanical stresses during operation.

Installation and connection

Installation of the filter insert involves removing the existing insert from the flanged filter housing and replacing it with the new unit. The connection is made via flanged PN16 fittings according to EN 1092-1 standards. The EPDM gasket ensures a tight seal between the insert and the housing. Before installation, verify that the housing is clean and free of debris. Ensure the drain screw is properly positioned to allow for periodic cleaning. Common installation mistakes include using incorrect gaskets, misaligning the flanges, or failing to check the integrity of the sealing surface. After installation, perform a visual inspection and pressure test to confirm a secure fit and absence of leaks.

Compatibility and accessories

This replacement filter insert is specifically designed for use with the IVAR series BRA.11.000 and BRA.11.000 M flanged filters. It is not interchangeable with other filter models due to differences in dimensions and sealing requirements. When ordering, ensure that the DN size matches the existing filter housing. Additional items required for installation include a wrench for tightening the flanges and possibly a cleaning tool for the drain screw. No other accessories are typically needed unless specified by the system design.

Technical background for designers

The filter operates by allowing fluid to pass through a stainless steel mesh, which traps suspended particles. The mesh porosity ranges from 0.8 mm to 1.6 mm, depending on the size, and is selected based on the expected particle size in the system. The cast iron body provides structural strength and resistance to corrosion in water-based systems. The EPDM gasket ensures a reliable seal and is resistant to water and glycol mixtures. The filter is integrated into the system between two flanges, and its performance depends on correct alignment and sealing. Long-term efficiency is influenced by the frequency of cleaning and the quality of the fluid being filtered.

Service and operation

Regular maintenance is necessary to ensure the filter continues to function effectively. The filter should be inspected periodically for signs of clogging, corrosion or mechanical damage. The drain screw can be used to remove trapped particles and clean the interior. In systems with high particulate load, more frequent cleaning may be required. No specific service intervals are provided in the documentation, so maintenance should be performed based on system performance and visual inspection. During operation, monitor for pressure drops across the filter, which can indicate blockage and the need for cleaning or replacement.

Frequently asked questions

Can the filter insert be used with glycol-based fluids?
Yes, the filter insert is suitable for use with water containing up to 50% glycol. The materials used are compatible with this type of fluid.

Is the filter insert suitable for steam systems?
No, the filter insert is not recommended for use with steam or gaseous media. It is designed for liquid applications only.

What is the maximum temperature range for this filter insert?
The filter insert operates within a temperature range of -10°C to +100°C, making it suitable for most HVAC and water distribution applications.

Can the filter insert be cleaned and reused?
Yes, the filter insert can be removed and cleaned manually using the drain screw. However, it is recommended to inspect the gasket and screen for wear after each cleaning.
