Sintered Filters & Sintered Filter Media

Carbis Filtration manufacture high quality sintered metallic and polymeric filters, and sintered filter media. We offer finished parts of varying designs and shapes with flexibility of product form to suit numerous applications.

Carbis Sintered Polymer Filters and Parts

Carefully controlled thermal treatment and precise processing technology, allows us to offer porous parts with exceptional properties. With a broad range of powder grades at our disposal we can offer parts with varying porosity and geometry suitable for a wide range of applications.

By blending different grades the range of properties obtained can be considerably extended. Grades of varying particle size distribution, apparent density, surface area and molecular weight can be chosen offering good strength and rigidity.

Carbis Sintered Filters In Depth

Flow resistance and permeability depend on pore size, product density and thickness. Product density and porosity can be influenced by choice of sintering parameters and polymer grade. Porosity can be adapted to individual requirements within a wide range, for example if it is necessary to remove very fine contaminants form gases a maximum filter fineness of 1-2 m with a pore size of 10 m is recommended. For liquids a maximum filter fineness of 2-4 m is required, however this is dependent on particle structure, thickness of the filter media and contaminant.

Our polymers can be formulated with additives for special applications such as carbon black offering anti-static properties and hydrophobic adjustment using surfactants.

Semi-finished products can be fabricated into complex shaped finished parts thanks to the versatile machining properties of the material, parts can be milled, drilled, turned and punched. We can also weld and bond sections, allowing the manufacture of large finished products such as fluid bed plates up to 3 mtrs diameter.

Carbis Sintered Wire Cloth

Multiple layers of woven wire mesh laminated together using a diffusion-bonding process (more commonly known as sintering). This process combines heat and pressure to permanently bond
multi-layers of mesh together. The same physical process used to fuse individual wires together within a layer of wire mesh is also be used to fuse adjacent layers of mesh together. This creates a unique material offering excellent mechanical properties.

Perforated Plate

Multiple layers of diffusion-bonded wire cloth can be pleated to maximize filter area and on-stream life. Contaminants are captured on the upstream surface of the media, where it is easily removed or backwashed.

Our sintered mesh panels are manufactured in 300×1500 mm panels, these panels may be cut into smaller sections or laser cut into discs and custom shapes or formed into cones and cylinders. Larger sheets can be produced by welding several panels together, for applications such as fluid bed driers.

Pleated Mesh Element

Carbis Sintered Metal Mesh

Cylinders of sintered metal mesh combined with our wedge wire screens as supports, offer high pressure, back washable elements suitable for the most demanding of applications.

Our standard stock material is manufactured in 316LSS, however we also offer material in 22%Cr Duplex, 25%Cr Super Duplex, Alloys 400 and 600 and Titanium.

Carbis Sintered Metal Fibre

Stainless steel fibres manufactured using a diffusion bonding process. The combination of fibre weight, diameter and porosity produce a media that offers high permeability, low pressure drop and high dirt holding capacity. The fibre media can be supported between two or more layers of wire cloth and pleated offering high flow filter elements and candles. Manufactured as standard in 316SS, with some exotics available.

Sinter Wedge Wire Screen

Carbis Sintered Porous Metal Powder

Sintered porous metal is a proven, reliable, long-lasting media offering efficient particle removal, flow control, sound attenuation, and gas/liquid contacting. Our strictly controlled sintering process produces uniformly-sized pores in micron ratings from 0.2 to 200. Metallic particles of defined shape and size are
pre-formed and then metallurgically bonded. The interstices between the sintered particles form a permanent structure of pores whose size and distribution depends on both the raw material and the sintering process itself. We offer our sintered pours material in 316SS and Titanium as standard with some exotics available dependant on quantity and complexity.
