Mesh Filter in Cast Iron – Reliable Protection for Installations

The mesh filter type 821F is a robust solution designed to protect water, heating, and industrial systems from mechanical contaminants. The construction, based on a gray cast iron body, ensures durability and corrosion resistance, while the stainless steel insert guarantees effective trapping of impurities. This filter is suitable for hot and cold water systems, steam lines, industrial processes, and applications in heating, cooling, and air conditioning systems.

Construction and Applications

The 821F filter features a compact design that allows installation in confined or hard-to-reach areas. The ability to clean the filter without removing it from the pipeline is an additional advantage, minimizing downtime and reducing operational costs. Flanges are machined in accordance with EN 1092-1 (for body material group F) and EN 1092-2 (for material groups A, C, D), ensuring compatibility with existing infrastructure. Testing and inspections conducted in compliance with EN 12266-1 confirm the high quality and reliability of the device. The filter meets the requirements of the Pressure Equipment Directive 97/23/EC and bears the CE marking for nominal diameters DN ≥ 32.
