Additional options
Assembled Filter Elements
For manufacturing filter elements of large length (over 400 mm), we use assembly methods with press fit or threaded connections.
Anodizing and Oxidation
To enhance corrosion resistance it is possible to perform anodizing or micro-arc oxidation treatment on the entire internal surface of pores.
Multiple filtration grading
Different pore sizes combination in a single part allows to get universal filter cell for both coarse and fine filtration.
Products
Filtration at the moment is the main application field of ALUPOR™ . More than 400 companies, especially in oil and gas engineering, have successfully implemented our filter cells to their filtration equipment.
You can choose from the standard products series described below. Otherwise, we can design the analogue of filter cell you need or even develop the new filter element according to your specifications. For detailed info about ALUPOR™ properties go to following link.
Please choose the type of filter element and filtration parameters to make the order. If you need the advice about the material please don’t hesitate to ask us.

An open porosity material, porous aluminum has been applied for filtration of different media. A few examples of types: Filter Discs, filter cylinders, Filter Plates, Filter Tubes, Fine clean filters, Liquids filters, Hot gas filters, Hydraulic filters, Cooling water filters and more.
We make filters and filter cells with differend shapes and sizes by your specifications starting from unique single products up to serial product: pre-filtration (coarse filters), filtering membranes, filter discs, filter plates, and more. Filters made of porous aluminum can be easily cleaned/ regenerated by surface treatment, back washing; solvent washing, roasting or calcination. The filters service life can be extended up to 5-7 years by this manner. Items made of porous aluminum can be installed for consolidated purposes, for example, filter – silencer. Filter-silencers decrease the noise level and clean the exhaust air in pneumatic equipment.
Aluminium is regularly used for heat transfer as this material has high termal conductivity. This characteristic together with high porosity and open-porous structure give Alupor some extra advantages; porous aluminium can combine such applications as filtering and heat exchange.
Metal filters and sintered filter cells are intended for fine and coarse cleaning in industrial compressed air systems, air and technical gas supply, ventilation and dust removal; in industrial air supply systems for removal of water and oil emulsion or fog from the air.
Metal filter ensure the protection of your sensitive instruments and expensive equipment (i.e. gas distribution stations, oil and gas gears and pumps, etc) from oil, water, dust and other contaminants with 100% efficiency and reliability that can be achieved only with metal filters. Porous metal filters ALUPOR are installed in numerous equipment in oil&gas industry, compressed air equipment, chemical industry. The particles till 5 microns can be removed from the liquid or gas media with low level of pressure drop.
