STEEL FILTER CAP 3X6.9X12 30MICRON

The STEEL FILTER CAP 3×6.9×12 30MICRON is a miniature sintered metal filter element engineered by DALON for precision gas and air filtration in confined or compact spaces. With an inner diameter of 3 mm, outer diameter of 6.9 mm, and total length of 12 mm, this filter cap is ideal for integration into sensor assemblies, micro pneumatic devices, and metering valves.

Manufactured through metal powder sintering technology, the filter cap achieves rigid structural integrity, uniform porosity, and excellent particle retention down to 30 microns. It operates reliably in high-pressure, high-temperature, and corrosive environments, making it ideal for demanding industrial and laboratory conditions.

Reusable and cleanable, this filter cap is a sustainable solution for systems where filter replacement must be minimized due to access or cost limitations.
