Mesh filter model 821F, DN65 PN40, mesh opening 1.25 mm (28 openings/cm²). Body material: gray cast iron. Max. temperature: 450 °C 821F065E49

The 821F mesh filter is a reliable industrial valve component designed to protect systems from mechanical contaminants. The gray cast iron construction ensures strength and corrosion resistance, while the stainless steel insert guarantees effective filtration. This model is suitable for hot and cold water systems, steam, and various industrial applications, including heating, cooling, and air conditioning systems.

Construction and Application

The 821F filter features a compact design that allows installation in confined spaces. The ability to clean the filter without removing it from the pipeline is an additional advantage, minimizing downtime and reducing operating costs. The stainless steel insert provides high corrosion resistance and long service life. The filter is certified according to EN 1092-1 for the body material (Group F) and EN 1092-2 for materials A, C, and D. Testing and inspections are performed in accordance with EN 12266-1, and the product complies with the Pressure Equipment Directive 97/23/EC and bears the CE marking for nominal diameters above DN32.

The filter body is manufactured from gray cast iron, ensuring mechanical strength and corrosion resistance. The filtration insert, made of stainless steel, ensures efficient filtration and extended equipment lifespan. The nominal diameter of the filter is 65 mm, making it suitable for a wide range of applications. It operates at a nominal pressure of up to 40 bar and a maximum temperature of 450°C. The filter cover is secured with bolts, facilitating maintenance and easy replacement of the filtration insert. The flanged connection ensures tightness and durability when connected to the pipeline. The mesh opening size of 1.25 mm (28 openings/cm²) provides optimal filtration for the intended medium.

This filter is compatible with calculation programs such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, simplifying integration into installation projects. Alternative insert sizes (0.25 mm to 1.6 mm) and special configurations, including magnetic inserts (upon request), are also available.
