Basket strainer figure 821A, DN25 PN16, mesh size 1mm (45 meshes/cm2). Body material: cast iron. Max. temperature: 300 °C. 821A025C50

Mesh filter for installation protection

The 821A mesh filter is a reliable solution for trapping impurities in water, steam and industrial technology installations. The gray cast iron construction provides strength and corrosion resistance, while the stainless steel insert guarantees effective filtration.

Construction and application

This filter is used in a wide range of installations – from domestic heating and hot water systems, through industrial steam installations, to advanced heating, cooling and air conditioning systems. Its compact design makes it easy to install even in limited spaces. The ability to clean the filter without having to disassemble it from the network is another advantage that minimizes downtime and operating costs. Flanges made in accordance with EN 1092-2 ensure compatibility with existing infrastructure.

Key features and benefits

• Stainless steel insert: Provides long-lasting and effective filtration, protecting installation components from damage caused by contaminants. A 1 mm mesh size (45 meshes/cm²) effectively traps solid particles.
• Gray cast iron: The housing material is characterized by high mechanical strength and corrosion resistance, which translates into a long filter life. Material grade GG 25 (GJL-250) meets the requirements of many industrial applications.
• Easy maintenance: The ability to clean the filter without disassembly greatly simplifies the maintenance process and minimizes downtime in installation operation.
• Compliance with standards: The filter has passed tests and research in accordance with EN-12266-1, which confirms its safety and reliability. The installation length in accordance with EN 558-1 series 1 facilitates integration with existing systems.
• Wide temperature range: The ability to operate at temperatures up to 300°C expands the range of filter applications, including high-temperature installations.
• Safety: The filter design has been designed with user safety and minimal environmental impact in mind.
• Cover mounting method: Screw fastening ensures tightness and easy access to the filter interior during maintenance.
