Mesh filter model 821F, DN20 PN40, mesh opening 1 mm (45 openings/cm²). Body material: gray cast iron. Max. temperature: 450 °C 821F020E50

Mesh Filter – Reliable Protection for Installations

The mesh filter model 821F is a critical component in any system requiring precise medium filtration. The use of a stainless steel insert ensures durability and corrosion resistance, while the robust gray cast iron housing provides strength even under demanding operating conditions. This filter effectively removes mechanical contaminants, protecting sensitive system components from damage and failure.

Construction and Applications

The filter design is based on a proven solution featuring a mesh insert with 1 mm openings (45 openings/cm²), ensuring high filtration efficiency. Designed for nominal pressure PN 40, it performs excellently in hot and cold water systems, steam lines, and industrial processes. It is also suitable for use in heating, refrigeration, and air conditioning systems. The flanged connection (per EN 1092-1) simplifies installation and integration with existing infrastructure. The cover is secured with screws, enabling easy access to the filter insert during maintenance and cleaning.

• Wide range of applications: Ideal for water, steam, technological media, and heating and air conditioning systems.
• Durable construction: Gray cast iron body provides resistance to high pressures and temperatures (up to 450°C).
• High filtration efficiency: Stainless steel insert with 45 openings/cm² effectively captures mechanical contaminants.
• Easy maintenance: Filter cleaning without removal from the system minimizes downtime and operating costs.
• Compliance with standards: Meets Pressure Equipment Directive 97/23/EC and carries CE marking for DN ≥32.
• Housing material: Steel, enhancing mechanical strength.
• Pressure class: PN 40, ensuring safe operation under demanding conditions.
• Material grade: Cast steel, guaranteeing high manufacturing quality.

This filter complies with EN-12266-1 standards and features flanges machined according to EN 1092-1 for body material F, and EN 1092-2 for materials A, C, and D, enabling seamless integration with various industrial systems. Magnetic inserts (available on request) further enhance filtration efficiency by capturing ferromagnetic particles.
