It is a non-woven media-constructed through the randomly laying short metal fibers then subjected to sintering and bonding.
Sintered metal fiber felt is best suited for use in applications that operate under very high pressure, high temperature, and corrosive environments.
The fleece of the metal fiber can comprise different layers of fiber.
They can be compressed together to a suitable thickness then sintered to fuse the respective single fibers.
The resulting material is a highly porous fiber that is very strong, resistant to corrosion, high temperature, and fracture.
Furthermore, it has excellent permeability and can last longer compared to common media.
Sintered fiber felt
A sintered metal fiber felt is a porous material that offers superior filtration capabilities over other types of filtration media.
It has excellent filtration properties, which makes it a good choice for constructing a filtration element.
Consequently, you can add the material as a single layer on a sintered filter element or sintered mesh.
You can also sinter together multiple layers of the materials to construct a complete filter media.
Sintered metal fiber felt
Filter elements constructed using sintered metal fiber felt follow similar principles to other types of media.
However, the characteristics of the media, such as high porosity, increase permeability up to 20 times compared to other types of media.
Typically, you can use this type of media for filtering either gases or liquids.
A sintered metal fiber provides a porous and torturous path which blocks and retains the particles as the process fluid passes through the depth filters.
With time, the captured particles create cake deposition on the surface of the media though more particles stick on the previously retained particles.
Where the incoming gas is heavily contaminated, then cake filtration plays a unique role in dust removal.
Here, particles quickly create a filtration cake on the surface of the medium that further results in more pressure drop.
As more particles lodge on the surface, the pressure drop increase until the filter reaches the terminal pressure drop.
In self-cleaning filters, cleaning is initiated, and a clean gas/liquid is released in reverse flow to dislodge the cake.
As the particles move through the porous material, they hit and stick on the fibers through four main mechanisms. These mechanisms include:
Cleaning could restore the pressure drop to initial levels if the pore sizes were appropriately chosen.
However, complete regeneration will not be possible if the dirt load is progressively lodged inside the porous media during the forward flow.
You can prepare a sintered metal fiber felt by simulating the following procedures below.
Remember, this is the procedure you can use for the preparation of sintered stainless steel fiber felt.
You can use sintered metal fiber felt in numerous applications requiring fine, deep, and sub-micron filtration such as:
Sintered metal fiber felt of superior quality should possess the following features:
Depending on the type of construction metal, the sintered metal fiber felt can withstand temperatures of up to °C.
Similarly, you can also use the fibers on corrosive applications, which would otherwise corrode ceramics, polymers, and non-metallic textiles.
Sintered metal fiber felt has up to 85% high porosity. The high porosity enables the fiber to support up to 20 times more flow rates than other media types.
It also makes the material last longer on-stream and allows downscaling, where you will use a lesser filter surface to purify equivalent fluid volume.
The low-pressure drop is a result of the high fiber porosity.
It will help you save energy costs, particularly under high filtration velocities.
You can use sintered metal fiber felt in constructing both surface and depth filters.
When applied for surface filtration, you will achieve efficient filtration results as a consequence of cake accumulation.
Similarly, its high dirt holding capacity also makes it highly suitable for depth particle capture when it is used to construct depth filters.
Media constructed from sintered metal fiber felt have longer service life by a factor of 2 to 3 times compared to conventional media such as wire mesh.
The material has an open structure which enables easy cleaning through backflushing or back pulsing in situ.
The in situ cleaning reduces downtime costs and enhances profit margins because you don't have to halt production.
Constructing the metal fiber involves sintering, which generates strong fiber bonding, which guarantees high-strength filtration media production.
Filter elements constructed using the material can withstand very high pressure, thermal shock, and frequent backflushing when supported with an excellent inner core.
It has a thin membrane that enables quick and easy cleaning, pleating, shaping, and welding.
The thin membrane also enhances the capability of responding to backwashing and back pulsing.
You can choose the most suitable sintered metal fiber felt from a material of your liking.
These metals are break-proof, weldable, have a low thermal expansion, and others can be cleaned using chemicals.
You can use these fiber felts for HEPA and ULPA filters because they can remove particles down to 0.1 microns.
You can also use them for making screens that can retain particles as large as 100 microns.
You can use diverse types of metals and various alloys to construct a high-quality, sintered metal fiber.
Stainless steel 316L is the most widely used material.
You can also choose any of the materials below:
You need to understand the construction, advantages, and drawbacks of each product.
That will make it easier to compare the two products.
The main difference between the two products is in manufacturing because you can use similar metal alloys to manufacture each.
For metal sintered fiber felt, you first break the desired alloy into fiber-like, cut them into small pieces then thread them together by penetrating a needle.
Subject the knitted fiber through a sintering process to develop a permeate bond among the individual fibers.

You can conduct two main types of tests for sintered metal fiber felts.
They include:
Sintered metal fiber felt
You should carry out the test as specified under ISO guidelines.
The test lays down methods of determining the pore size of the porous structures such as bearings, electrodes, and filters.
Note that you can only use the test for quality control but not for grading filters.
Accordingly, you can consider the following for the test:
You should conduct the test according to the guidelines of ISO .
You can follow these steps to perform the test.
Use a flexible seal to reduce the effects of surface irregularities that would otherwise cause leakage.
The sintered metal fiber filter grades depend on the pore size rating.
Consequently, the fibers are rated using an absolute rating scale based on the size of pore openings in the media.
The final rating of the sintered metal fiber felt filter element depends on the layer's used layer weight and composition.
Several layers have been bonded together, then cumulative weight and the fiber content of the layers determine the final rating.
The effectiveness of a sintered metal fiber felt significantly depends on the following factors:
When you choose an appropriate sintered metal fiber felt to construct filter elements, you will get a quality product that meets industry requirements.
There are many things you need to know when selecting sintered metal fiber felt.
Ensure that you suit the following vital materials and properties to match your system requirements.
The high porosity characteristic of a sintered metal filter gives the filter long service life, usually 2 to 3 times the lifespan of other common filter elements.
Yes, you can clean and reuse a sintered metal fiber felt. Cleaning helps you save on energy and helps protect the environment.
Consequently, you can use the following methods to clean a sintered metal fiber felt:
It is the most preferred and effective method for cleaning solvents involving acids and bases. It is also best suited for collecting polyester condensation.
It involves ultrasonic sound, which produces cavitation and continuous burst responsible for removing particles trapped inside the fibers.
This type of cleaning removes contaminants embedded in the fiber material by pumping a clean liquid, usually water, in the reverse direction to normal flow.
Backflushing method is the most suitable for cleaning the fiber when the operation is on. It involves a periodic reversal of the system fluid to clean the filters.
It is a promising alternative to cleaning that removes non-adhesive, external contaminants.
Using this method, you don't have to stop production for cleaning because the fluid flow is reversed for only a fraction of a second.
The main difference between this method and the others is the force and duration.
Back pulsing employs a strong force and lasts less than a second, whereas backwashing can take a minute or more and uses lesser force.
The cost will vary depending on the type of metal used and the fiber size felt, among other factors.
For instance, stainless steel sintered metal felt can cost between $5 to $50 apiece, while sintered metal fiber felt constructed using nickel will cost between $20 to $80.

The standards are not legally binding and only acts as guidelines from which other countries or trade unions can forge their standards.
The standards include:
The dirt holding capacity is the quantity of dirt that the filter element can retain before it reaches the terminal pressure drop.
You can use different methods to determine the dirt-holding capacities, such as multi-pass test, continuous or batch injection test, and single-pass test.
However, the multi-pass test under the guidelines of ISO (formerly ISO ) is the most commonly used.
Using the multi-pass test, you will need to continuously inject ISO medium test dust in the form of slurry in the reservoir upstream.
The setup simulates the actual lubricating or hydraulic system and allows the dirt not captured in the first round to recirculate the system.
You will use the bubble point test to determine the pore size of the metal fiber felt.
In principle, under constant wetting for a given fluid and pore size, the size of the hole is inversely proportional to the pressure required to push air bubbles out of the pore.
The initial test results for a bubble point procedure give the size and location of the largest pore.
The open bubble point pressure reading determines the mean pore size of the fiber.
The process of making fiber involves sintering and compression.
The process creates strong bonds between individual fibers, exponentially increasing the fiber's mechanical strength and resistance to corrosion.
It also prevents coarsening of the crystal grains found inside the fibers.
