The stainless steel sintered fiber pleated filter element is made from metal fibers that are sintered at high temperatures to form a durable, multi-layer, and deep-porous filtration medium.
With a pleated (pleated-type) structure, the filter provides a significantly larger filtration area, ensuring high flow capacity and stable filtration efficiency.
It is widely used in fuel exhaust purification systems including diesel exhaust, generator exhaust treatment, and industrial fuel-burning emission control.
Fuel exhaust temperatures typically range from 300°C to 650°C.
Sintered fiber material maintains exceptional stability under high heat without melting, deforming, or degrading, making it ideal for exhaust gas filtration.
The 3D porous metal fiber structure effectively captures fine and sub-micron particles.
Filtration rating ranges from 1–30 μm, and the pleated design greatly increases the effective filter area while reducing pressure drop, ensuring smooth exhaust flow.
Fuel exhaust contains sulfur compounds, NOx, moisture, and combustion residues, which are highly corrosive.
316L/304L stainless steel provides strong resistance to chemical corrosion.
The metallic fiber structure also withstands reverse-pulse cleaning or vibration impact without breaking.
Unlike disposable filters, stainless steel sintered fiber filters can be cleaned using ultrasonic washing, back-flushing, and chemical cleaning.
This significantly extends service life—often lasting several years—and lowers maintenance and replacement costs.
