Mesh filter model 821F, DN50 PN40, mesh opening 1 mm (45 openings/cm²). Body material: gray cast iron. Max. temperature: 450 °C 821F050E50

The 821F mesh filter is a reliable industrial valve component designed to protect systems from mechanical contaminants. The gray cast iron body ensures strength and corrosion resistance, while the stainless steel insert guarantees effective filtration. This filter is widely used across diverse applications—including hot and cold water systems, steam networks, industrial processes, district heating, refrigeration, and air conditioning.

This model, with a nominal diameter DN50 and nominal pressure PN40, offers high performance and durability. The mesh with a density of 45 openings/cm² (1 mm) effectively captures contaminants, ensuring uninterrupted system operation. A key advantage is the ability to clean the filter without removing it from the pipeline, simplifying maintenance and minimizing downtime.

The 821F filter complies with the Pressure Equipment Directive 97/23/EC and bears the CE mark for DN≥32, confirming its safety and conformity with European standards. Testing and inspections conducted in accordance with EN-12266-1 further ensure high product quality. Flanges are machined in compliance with EN 1092-1 (for body material group F) and EN 1092-2 (for material groups A, C, D), facilitating easy installation and integration with existing infrastructure.

• Robust construction: Gray cast iron body provides resistance to high pressures and temperatures (up to 450°C).
• Effective filtration: Stainless steel insert with 45 openings/cm² mesh efficiently removes mechanical impurities.
• Easy maintenance: Filter can be cleaned without disassembly, significantly simplifying servicing.
• Standards compliance: Meets requirements of Pressure Equipment Directive 97/23/EC and EN-12266-1.
• Versatile application: Ideal for water, steam, and industrial process systems.
• Safety assurance: CE mark for DN≥32 confirms compliance with European safety standards.

This filter is available in multiple body material variants (gray cast iron, ductile cast iron, carbon steel, or stainless steel) and pressure ratings (6, 16, 25, or 40 bar), allowing precise matching to specific system requirements. Optional inserts with varying mesh densities are also available—from 0.25 mm (600 openings/cm²) to 1.6 mm (15 openings/cm²)—to suit different filtration needs.
