Sintered Metal Fiber Felt Filter Cartridge

These filter cartridges are made from Sintered Fiber felt media.

SS316 fibers are compressed together and sintered to make SS316 Fiber felt media. This non-woven felt media is then used to manufacture cartridges. The End Caps as well as the seams are welded.

Resins/Adhesives not used in the manufacture of these types of cartridges.

Sintered stainless steel fiber felt offers efficient filtration with an extremely high porosity, capturing particles effectively. These durable filter cartridges resist corrosion, making them ideal for demanding environments. The sintering process enhances their integrity, ensuring reliable filtration for various fluids and contaminants. With superior dirt holding capacity and extended service life, sintered stainless steel filters are the preferred choice for critical applications.

Filtration of powders, trapping particulates from vacuum / compressed air lines. Filtration of gels from molten monomers at high temperatures etc.

What are Sintered fiber felt Filters?

Sintered Metal Fiber Felt is created through a process where metal fibers are randomly lay down to form a filter media. This non-woven stainless steel fiber filter media is then compressed and sintered at a specific temperature and atmosphere. This results in a uniform filtration solution with high porosity, achieved through sintering and bonding.


This depth-based filtration medium effectively captures particles within its structure, making it an excellent choice for removing pollutants. Compared to wire cloth, non-woven metal fiber offers higher porosity, uniform distribution, and greater dirt holding capacity. It can also be welded and folded into different shapes, enhancing its versatility. One downside is the lower strength of the media.


The Sintered Metal Fiber Felt series delivers high filtration efficiencies through a combination of depth and tortuosity, along with exceptional dirt holding capacity and flow characteristics. Multiple layers of metal fiber felt can be sintered together to create effective filter media.

Applications of Sintered Metal Fiber Felt Filter Cartridge

Polymer Filtering: Utilizing polymers like polyamide, polyester, polypropylene, and nylon for filtration purposes, offering diverse options for efficient particle capture.

Filter Powder Collection: Gathering particles from vacuum and compressed airlines, ensuring clean and purified air in various industrial applications.

Automotive Air Filters: Used in automobile air filters, lubricant filters, gasbag aerators, and chemical recycling processes, ensuring optimal performance and longevity.

Hydraulic and Fuel Filtration: Crucial for maintaining clean hydraulic systems and fuel quality in machinery and vehicles, enhancing overall performance and reliability.

Filtration of gels from molten monomers: Sintered fiber felt filters find critical applications in filtering gels from molten monomers at high temperatures. The sintered fiber felt filters effectively capture and remove impurities and contaminants from molten monomers, ensuring a clean and smooth manufacturing process.

High temperature gas filtration: Sintered fiber felt offers a very low resistance to air flow, due to its very high porosity. Since the media is stainless-steel based, the media can be operated at 350 C continuously without any problems, depending on the nature of gases to be filtered.


Why connect with Kumar Process for Sintered Metal Fiber Felt?

Our all-welded design of fiber-felt cartridges makes them a robust, high-temperature capable, and reusable alternative to paper/cloth based pleated cartridges. Welding of fiber-felt is an art, and it is very easy to burn through, compromising the filter. We have developed automated techniques for reliable welding, thus ensuring that the filters are not compromised during operation and regeneration.
