STEEL FILTER ELEMENTS 3X46X2 0.5MICRON

DALON’s sintered air filter element in 3 mm × 46 mm × 2 mm format delivers ultra-fine 0.5-micron filtration for highly sensitive gas and air filtration applications. Engineered from sintered stainless steel powder, this disc element offers superior particle retention, flow stability, and operational longevity in a compact, low-profile format.

Using precision powder metallurgy, DALON manufactures this filter element by compressing and sintering stainless steel powder under high temperature, forming a rigid, interconnected porous matrix. This structure provides highly accurate filtration for dust, aerosols, micro-contaminants, and oil mist, while maintaining high permeability for clean air delivery.

Its 0.5µm nominal rating makes it suitable for critical applications such as medical air systems, laser and sensor gas purging, pneumatic controls, and ultra-clean gas lines in semiconductor or laboratory systems.

This compact disc filter is ideal for inline assembly, pressure balancing, ventilation protection, or final-stage filtration in high-purity environments.
