Oblique flanged filter figure 821 DN25 PN16 with magnetic insert, mesh size 1 mm, 45 meshes/cm², construction: C70 821A025C70

Oblique Flanged Filter – Reliable Protection for Installations

The oblique flanged filter type 821, with nominal diameter DN25 and pressure rating PN16, is a robust solution for mechanical purification of media in diverse installations. Designed for operation with water, steam, compressed air, oil, glycol, and other neutral fluids, it effectively removes contaminants and protects sensitive system components. The filter’s design enables easy maintenance and servicing, resulting in minimal downtime and extended service life.

Construction and Application

The filter features an oblique design with flanged connections, facilitating straightforward installation and integration into existing infrastructure. Constructed from ductile iron EN-GJS-400-18-LT, it ensures high strength and corrosion resistance. A key component is the magnetic insert, which efficiently captures ferromagnetic particles, providing additional protection against system damage. The stainless steel mesh screen with a density of 45 mesh/cm² and 1 mm aperture ensures effective retention of contaminants of appropriate size. This filter is widely used in heating, cooling, industrial, and sanitary systems.

Key Features and Benefits

• Magnetic Insert: Provides enhanced filtration by capturing ferromagnetic particles—especially critical in systems where such contaminants can cause rapid wear of components.
• Robust Construction: The ductile iron body ensures resistance to pressure (PN16) and long-term reliability, even under demanding conditions.
• Easy Maintenance: The design allows quick access to the filter element, enabling simple replacement without specialized tools.
• Wide Application Range: Compatibility with various media makes this filter a universal solution across multiple industries.
• Standard Construction C70: Features a 1 mm mesh aperture with 45 mesh/cm² density—optimal for most industrial and installation applications.
• Operating Temperature: Maximum operating temperature of +350°C enables use in high-demand applications.
