The flat form of the sintered fiber felt element, cut to a disc and stacked into the pack — rated 0.5–50 μm.
A sintered metal fiber felt disc rated 0.5–50 μm, cut flat and stacked into the housing. Contaminant is held through the depth of the felt wall, so the disc carries more before the differential pressure becomes the limit. Discs are cut, flanged and welded in house, then batch-tested for bubble point and air permeability. Service temperature holds to 600 °C.
The sintered metal fiber felt disc is the flat form of the element: a fiber mat sintered into a sheet, cut to a disc and stacked or clamped into the housing. It suits duties where the filtration area is set by the disc diameter and the number of discs, and where the element has to be taken apart, cleaned and put back. Ratings run from 0.5 to 50 μm, in liquid and gas service up to 600 °C.
Because the rated layer is a fiber mat and not a woven opening, contaminant is held through the depth of the wall. A disc holds more before the differential pressure becomes the limit than a comparable mesh disc, and it tolerates the repeated cleaning cycles that a stacked disc pack usually sees.
Discs are cut, flanged where the pack needs it, and welded to the support layers and connection detail in our own plant — TIG, resistance or laser welding on stainless, titanium and nickel alloys. Sintered fiber felt is bought in to specification; the forming, welding and testing are ours. Every batch is measured for bubble point and air permeability, and the record travels with the dispatch. Where the pack needs a support layer under the felt, or a flanged edge to seat the disc, both are welded before the disc leaves the shop.
Send a drawing, an OEM part number or a used disc and we confirm the equivalent from diameter, thickness, micron rating, alloy and the way the pack is held and sealed. Where the disc is designed from the duty instead, send temperature and peaks, medium and corrosives, working pressure and differential, contaminant and its size distribution, the rating with any bubble point or permeability target, flow and disc count per housing, and the geometry. Drawing review takes 3–5 working days, and the dimensioned drawing comes back for your approval before a price does.
Key Benefits
01
Filtration area follows the disc diameter and how many discs the pack holds, so the element is sized to the housing instead of to a catalogue.
02
The felt holds contaminant through the wall rather than on one surface, which is what a disc that is cleaned and re-stacked needs.
03
The pack comes apart, so single discs can be cleaned, inspected and put back, and a line cleans on its own schedule.
04
The sintered fiber structure holds to 600 °C, past the point where paper and polymer discs stop being an option.
Construction
A coarse woven mesh over the upstream face, protecting the felt through handling and cleaning.
Metal fiber sintered into a mat and cut to the disc diameter. The micron rating and the bubble point are measured against this layer.
A coarser sintered layer downstream that carries the differential pressure, so the rated felt keeps its pore size in service.
The disc edge is flanged or welded where the pack needs it to seat and seal — TIG, resistance or laser welding.

Materials
The alloy follows the medium, the temperature and what the element has to resist. Where a duty sits between two of them, an engineer says which one and why.
Standard industrial duty where the medium is not aggressive.
Where chlorides or acids are present in the medium.
Heat-resistant grade for continuous high-temperature service.
Oxidation-resistant at temperature where stainless steel scales.
Nickel alloy for aggressive media where stainless is not enough.
Corrosive service and where high purity is required.
Hot aggressive media where stainless stops being enough.
Industries
The duties this element is bought for, and what it is filtering in each of them.
Polymer melt and spin-line filtration where the disc pack is cleaned between campaigns.
Process stream filtration on small housings where the pack is taken apart for cleaning.
High-purity gas and chemical service with an element that can be cleaned and reused.
Batch filtration where the element is cleaned and the batch record travels with it.
Customisation
Cut to your drawing: disc diameter, thickness, micron rating, alloy, edge treatment and how the disc seats in the pack all follow the housing or the OEM disc being replaced. Send a drawing, a part number or a used disc and we confirm the equivalent from dimensions, medium and connection before a price is given.
Send what you have — a drawing, a part number, a photograph of the element in place, or just the operating conditions. Nothing is quoted from a part number alone.

Why Us
Every element is welded and batch-tested in our own plant, and the batch record travels with the dispatch. About 70% of our work is a replacement for an element already in service, which is why a drawing or a used part is enough to start from.
Questions
The pack is sized to the flow the housing has to pass. Send the flow rate, the disc count per housing you run now and the housing envelope, and the disc diameter and count are set from those. The micron rating stays inside the 0.5–50 μm range of the felt.
Yes. Send the drawing, the OEM part number or a used disc and the equivalent is confirmed from diameter, thickness, rating, alloy and the way the disc seats and seals. Flange and edge details are matched to the pack rather than approximated.
The felt is washable and re-generable in both forms. A disc pack has the advantage that it comes apart, so individual discs can be cleaned, inspected and re-stacked. Tell us the cleaning method the line uses and we say whether it suits the felt.
304 or 316L covers most industrial duty, 316L where chlorides or acids are present, titanium for corrosive or high-purity service, and nickel alloys where the medium is aggressive at temperature. Send the medium, its concentration and the operating temperature.
Drawing review takes 3–5 working days, samples are made in 20–30 days and production runs take 30–60 days. The minimum order is a few pieces to a few dozen discs.
Bubble point and air permeability are measured on every batch in our own testing lab and the record travels with the dispatch. We work to ISO 9001, so the figures the discs were accepted against are the figures you hold.
