Cast iron mesh filter DN400 PN16 – reliable protection for installations

The mesh filter 821A is a robust solution for purifying media in industrial and utility systems. Manufactured from high-quality gray cast iron, it ensures durability and corrosion resistance. Designed for use with water, steam, and other media at temperatures up to 300°C, it acts as an effective barrier against mechanical contaminants. Its stainless steel filter element guarantees efficient removal of solid particles, protecting sensitive system components such as pumps and valves.

Construction and application – key to effective filtration

Filter 821A features a flanged connection compliant with EN 1092-2, simplifying installation and integration into existing infrastructure. The filter element, with a mesh density of 15 openings/cm² (hole size 1.6 mm), effectively captures contaminants, ensuring optimal system performance. Thanks to its cleanable design without disassembly, maintenance is simple and convenient. It is suitable for hot and cold water systems, steam systems, industrial processes, district heating, refrigeration, air conditioning, and power generation.

Design features and materials – guarantee of reliability

The filter body is made of gray cast iron (grade GG 25 / GJL-250), providing mechanical strength and resistance to nominal pressure of 16 bar. The filter element is constructed from stainless steel (X5CrNi 18-10), offering excellent corrosion resistance and long-term service life. The sealing gasket, made from a material other than standard (specific details unavailable), ensures tight connections. Bolted cover fasteners allow easy access to the filter element during servicing. The filter has undergone testing and inspection in accordance with EN 12266-1, confirming compliance with safety and quality requirements. The installation length conforms to Series 1 per EN 558-1.
