Product Details

AIDA metal felt filter media is made with thin filaments of nonwoven stainless steel. These Sintered Pleat Filter are ideal for high pressure, highly corrosive, highly viscous or radioactive applications. They feature extremely high porosity (up to 85%), high flow rates (up to 20 times higher than other media types), and very long life.

These elements are the same we use in our high pressure filter assemblies, which are often employed in highly challenging applications.

Random fiber filtration (metal felt) can provide absolute particle retention, longer on stream time and high dirt-holding capacity for under 60 micron filter elements. Although more expensive, it oftens offers clear advantages over wire cloth, sintered metal or non-metallic fibers. Its high temperature, high pressure and corrosion resistance combined with almost unending cleanability, make it highly economical for hostile environments.

AIDA Metal Felt Filter Element Specifications

AIDA metal felt filter elements have a random matrix of 316-L stainless steel filaments with diameters from 4 to 25 microns. The finer the micron, the more open area is provided in a pure crosshatch pattern. When sinter bonded, this random matrix can provide:

Extremely high porosity (up to 85%)

high flow rates: up to 20 times higher than other media types

long on-stream lifetime

downscaling is possible (less filter surface is needed to filter the same volume)

Low pressure drop: The high porosity of our metal fiber media allows a very low pressure drop (and thus lower energy cost), even at high filtration velocities

Ease of cleaning: The open structure of porous metal media allows you to clean in situ by backpulsing or backwashing

High strength: The sintering process creates strong fiber bonds and guarantees a high strength filter medium. Combined with an appropriate inner core, our filter elements can withstand thermal shock, high pressures, and frequent backpulsing.

Heat & corrosion resistance: Our filter media can be used in high temperature (up to 1000° C, depending on the alloy) and/or corrosive applications - where non-metallic textile, ceramic or polymer products fail

Can be used for surface or depth filtration. Our filter media enables you to achieve high efficiencies through a cake build-up (surface filtration) and also offer high dirt holding capacity for depth particles capture (depth filtration)

Stainless steel and other alloys available: not brittle, chemical cleaning is possible, weldable, low thermal expansion, maintains structure (no thermal shock) Depending on the performance you require, we select the proper alloy to provide the required resistance and strength

For filtration, the absolute filter ratings are:

for liquids — 1 to 80 µm

for air & gases — below 0.1 µm is possible
