Mesh filter model 821F, DN32 PN40, mesh opening 1 mm (45 openings/cm²). Body material: gray cast iron. Max. temperature: 450 °C 821F032E50

The 821F basket filter is a reliable industrial valve component designed to protect systems from mechanical contaminants. Constructed from gray cast iron, it ensures durability and corrosion resistance, while the stainless steel insert guarantees effective medium filtration. This model, with a nominal diameter DN32 and nominal pressure PN40, is suitable for a wide range of applications—including hot and cold water systems, steam lines, advanced industrial technologies, district heating, and HVAC systems.

The filter features high manufacturing quality and complies with relevant European standards (Pressure Equipment Directive 97/23/EC and testing per EN 12266-1), confirmed by CE marking for DN≥32. Thanks to a 1 mm mesh (45 openings/cm²), it effectively captures contaminants while minimizing pressure drop in the system. The ability to clean the filter without disassembly significantly simplifies maintenance and servicing.

Construction and materials:

The filter body is made of robust gray cast iron, providing resistance to high temperatures (up to 450°C) and aggressive media. The filtration insert is manufactured from stainless steel—a corrosion-resistant material ensuring long-term reliability. The flanges are machined in accordance with EN 1092-1 for body material F and EN 1092-2 for materials A, C, and D, facilitating easy installation and integration with existing infrastructure. The cover is secured with threaded bolts, ensuring tightness and convenient access to the filter insert.

Practical applications:

This basket filter is a versatile solution ideal for professional installers and end users alike. It performs exceptionally well in demanding industrial applications where protecting sensitive equipment from contamination is critical. Thanks to its design and materials, the filter excels at filtering hot water, cold water, and steam. It is an ideal choice for residential, commercial, and industrial installations. Additionally, its technical parameters make it suitable for use in district heating and HVAC systems.
