Mesh filter model 821C, DN25 PN25, mesh opening 1 mm (45 openings/cm²). Body material: gray cast iron. Max. temperature: 350 °C 821C025D50

The 821C mesh filter is a reliable solution for protecting installations against mechanical contaminants. Manufactured from high-quality gray cast iron, it ensures durability and corrosion resistance. This filter is widely used across a broad range of applications, including hot and cold water systems, steam lines, industrial processes, district heating, refrigeration, air conditioning, and power generation.

Construction and materials:
The filter body is made of gray cast iron (grade GGG 40.3 / GJS-400-18), guaranteeing strength and stability. The filter insert is constructed from stainless steel, ensuring effective trapping of contaminants. The filter mesh has a density of 45 openings/cm² (1 mm aperture), efficiently capturing solid particles and protecting sensitive system components from damage. The flanged connection (compliant with EN 1092-2) simplifies installation and integration into existing systems. Additionally, the cover can be secured with bolts, providing easy access to the filter insert for maintenance or replacement.

Operating parameters and applications:
The 821C filter has a nominal diameter DN25 and a nominal pressure rating of PN25. It operates at temperatures up to 350°C, making it suitable for applications requiring high thermal resistance. Due to these parameters, the filter performs excellently in hot water and steam systems. Its design enables safe operation under various industrial conditions—testing and verification have been conducted in accordance with EN 12266-1. The installation length complies with EN 558-1 Series 1.
