Mesh Filter – Reliable Protection for Installations

The mesh filter model 821C is an industrial valve component designed to protect systems from mechanical contaminants. The filter’s construction enables effective removal of solid particles from the flowing medium, ensuring long-term, trouble-free operation of the system. This model features robust construction and is suitable for use under a wide range of operating conditions.

Construction and Materials

The filter body is manufactured from gray cast iron (GGG 40.3 / GJS-400-18), providing high strength and corrosion resistance. The filter insert, made of stainless steel, ensures efficient filtration and long-term durability. The filter features a flanged connection compliant with EN 1092-2, facilitating easy installation and integration with existing infrastructure. The sealing element is made from a material ensuring tightness across a broad range of temperatures and pressures.

The 821C filter is available with a mesh opening of 1 mm (45 openings/cm²), making it ideal for capturing most common contaminants found in piping systems. This effectively protects sensitive components such as valves, pumps, and heat exchangers from damage and failure.

Applications and Operating Parameters

This filter is widely used in:

• Hot and cold water systems
• Steam systems
• Industrial processes
• Heating, cooling, and air conditioning systems
• Power generation

It can operate at a maximum temperature of 350°C and a nominal pressure rating of PN 25, making it suitable for demanding industrial environments. The filter’s design allows for easy cleaning of the insert without requiring disassembly from the pipeline, minimizing downtime and operational costs. The filter has passed testing and certification in accordance with EN-12266-1, confirming its quality and safety for use. The installation length complies with EN 558-1 Series 1, ensuring seamless integration into existing systems.
