A sintered wire mesh disc or disc stack — rigid, aperture-stable and cleanable, cut to your holder or stack height.
A sintered wire mesh disc cut from the same multi-layer sheet we roll into cartridges, supplied flat or stacked with spacers to the height the holder takes. Rating 1–200 μm and a rigid wall, so the aperture holds under differential pressure and the disc can be cleaned and reused. Batch-tested for bubble point and air permeability.
A sintered wire mesh disc is cut from the same multi-layer sintered sheet we roll into cartridges, so the layer stack, the rating and the pore stability are the same. What changes is the shape: a flat element that sits in a holder or is stacked with spacers into a disc stack. Ratings run from 1 to 200 μm, in liquid and gas service up to 600 °C.
The disc is the element to specify where the housing is flat rather than cylindrical: one disc in a small holder, or a stack of discs and spacers that builds the filtration area the flow needs. In a stack the flow is shared across the discs, so the number of elements per housing is part of what we size. Send the flow rate and we work it out with you.
Because the disc is cut from a sheet that was sintered before it was formed, the aperture does not move as differential pressure rises across a loaded element. That matters in a stack, where a disc that deformed would let flow past it and load the rest harder. It is also what lets a disc be cleaned and returned to service. A disc that is cleaned rather than replaced suits holders that are opened on a maintenance schedule, and it keeps a spare on the shelf instead of a stack of them.
Discing, rimming and welding are done in our own plant. The disc is cut and its edges finished; the rim, support or holder detail is welded by TIG, resistance or laser welding. Bubble point and air permeability are measured on every batch and the record travels with the dispatch. About 70% of orders are replacements against a drawing or an OEM part number; the rest are sized from the duty. Drawing review takes 3–5 working days, samples ship in 20–30 days and production runs take 30–60 days, from a minimum of a few pieces to a few dozen.
Key Benefits
01
The disc is cut from a sheet that was sintered first, so loading raises the differential pressure without opening the pore.
02
A disc that deformed would let flow past it and load the others harder; a rigid sintered disc holds its flatness and keeps the flow shared.
03
Reverse flow lifts the contaminant off the rigid surface, so the disc is cleaned and returned to service instead of being replaced.
04
Outside diameter, thickness and edge finish follow the holder or the OEM element, so a replacement drops straight in.
Construction
A coarse woven mesh on the working face, taking the handling and the first of the backwash.
The woven mesh that sets the rating and the bubble point; the disc is measured against this layer.
Spreads the flow over the rated layer so the disc works across its whole face.
A coarser sintered layer carries the differential pressure, with the rim or holder detail welded in house.

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.
General industrial duty; the disc is cut from the same 304 sheet we roll into cartridges.
Where chlorides or acids are present in the medium.
Heat-resistant grade for continuous high-temperature service.
High-alloy austenitic grade for chlorides and acids.
Nickel alloy for aggressive media where stainless is not enough.
Nickel-chromium alloy for high temperature with corrosion.
Nickel-copper alloy for chlorides and seawater duty.
Corrosive or high-purity service, where stainless would contaminate the stream.
Aggressive media at temperature, where stainless is no longer enough.
Industries
The duties this element is bought for, and what it is filtering in each of them.
Spin packs and small flat holders where the element is a disc rather than a cylinder.
Sample and slipstream filtration where a flat holder is fitted.
Cleanable discs for lines where the batch record has to travel with the part.
Disc stacks in gas service, where the element is cleaned and returned to service.
Customisation
Cut and finished to your holder: outside diameter, thickness, rating, alloy and the rim or support the holder needs. Where a stack is specified, send the stack height, the spacer arrangement and the number of elements per housing and we size the discs to it. Drawing review takes 3–5 working days.
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
As many as the housing height and the flow need. The stack height, the spacer arrangement and the number of elements per housing are part of what we size, so send those with the flow rate and we say what the stack should be.
It does. The sheet is sintered before the disc is cut, so the disc is rigid and does not bow as the differential pressure rises. That is what keeps the flow shared across a stack instead of passing one disc.
The edge is finished and the rim or support is welded in house to suit the holder. Send the holder drawing or the OEM part number and the seating and sealing detail are matched.
Both. One disc for a small holder and a batch of discs for a stack are the same work, from a minimum of a few pieces to a few dozen.
The rating is set by the control layer in the stack and is measured, not counted from a mesh. Send the required micron rating with any bubble point or air permeability target and the stack is selected against it.
Bubble point and air permeability on the batch, in our own testing lab, with the record travelling alongside the dispatch. That record is the figure the discs were accepted against.
