From automotive filters to filters in medical equipment, proper filtration of a wide range of substances helps make the world go round. This puts the onus on the engineer to determine the filter media to achieve the perfect balance of durability, accuracy and cost effectiveness.
As a preeminent manufacturer of metal wire mesh products, Tengde metal wire mesh is here to help you better understand whether it is the right filter for your filtration operation.
Metal mesh, also known as woven wire mesh, is a calculated array of individual metal wires that interlock together to form hole openings with precise dimensions. Specifications, such as mesh count, wire diameter, weave pattern, layer configuration and alloy, were predetermined prior to the centuries-old weaving process used to create the mesh.
Metal mesh can now be moulded and formed without compromising the integrity of the mesh. This allows it to provide ideal filtration for a wide range of industries.
Filter Element
Filters are known to be porous materials designed to remove impurities and miscellaneous particles from liquids and gases. In the field of filtration, a variety of materials are used as filter media, such as metal fibre mats and wedge-shaped wires.
A mesh filter is a network of metal wires forming a flexible filter cloth with precise, rigid pore openings that can be customised by engineers to suit most filtration systems. In addition, as wire mesh filters are one of the most durable filtration media available, they can be used in applications such as sanitary piping systems to remove contaminants or in applications such as suction filters to extract filter cake.
Metal mesh filters offer a number of benefits. These include the filter's cleaning ability, accuracy, flow rate and durability.
Let's take a look at how metal mesh provides the benefits listed.
One of the most significant advantages of metal mesh over most filter media in use today is its ability to provide adequate flow rates. This is possible because the wire diameter and mesh aperture can be customised to perfectly match the contaminants you want to filter, giving you a higher level of filter surface area.
This is particularly true when using a 3-dimensional metal mesh filter. This is because the 3D mesh filter offsets the two layers of filter cloth, doubling the achievable flow rate.
Although alloys such as Alloy 310, Inconel 600, Super Duplex, Duplex, Hastelloy C22 and Titanium can be used to construct metal mesh filters, the 300 series stainless steel is primarily used. This helps to create a filter that can withstand a wide range of impurities, pressure changes and temperature extremes without compromising the accuracy of the filter.
In addition, stainless steel is a very flexible material that allows the filter to be shaped to fit your filtration system and retain its shape after many uses.
The weaving process used to construct the mesh filters is carefully monitored from start to finish. The result is a filter with hole openings that are precise and uniform throughout the filter.
These precise holes ensure that the end product, whether filtered material or cake, is consistent and meets industry standards.
Because the metal mesh has precise pore openings, clogging and blockages are significantly reduced. This, combined with the enhanced flow rate, means that the system operator can easily clean the metal mesh.
These two features allow the mesh filter to backflush and remove any unwanted debris with minimal pressure.
