Sintered Metal Filter manufacturer is made of stainless steel wire mesh, or sintered metal fiber felt, which is sintered at each wire contact point to produce a strong surface-sieving porous filter cylinder. Moreover, the filter element is pleated design that further provides large filter area, good dirt holding capacity. Double open-ended or single open-ended is available as per customers' need, threaded end is often equipped with gasket, like o-ring, to reduce the friction of the corrugated filter. Unlike unsintered mesh, pleated sintered mesh filter enables the use of finer wires to produce more pores per unit area for higher contaminant loading capacity. On the other hand, pleated sintered filter cartridge is more preferred to replace the PP filter cartridge with its back washing and reusability advantage, in applications of corrosive liquid filtration, oxidizing liquid filtration, liquid and gas filtration, etc.
Ayater metal felt filter media is made of non-woven stainless steel filaments. These porous metal felt filter elements are ideal for high pressure, high corrosive, high viscosity or radioactive applications. They have extremely high porosity (up to 85%), high flow rate (up to 20 times that of other media types) and very long service life.
These components are the same as those we use in high-pressure filter assemblies, which are often used in extremely challenging applications.
Random fiber filter (metal felt) can provide absolute particle retention, longer flow time and high dust holding capacity of the filter element below 60 microns. Although more expensive, it usually has obvious advantages over wire cloth, sintered metal or non-metal fibers. Its high temperature, high pressure, corrosion resistance and almost unlimited cleanability make it very economical in hostile environments.
The SINFTFELT metal felt filter element has a random matrix of 316-L stainless steel filaments with a diameter of 4 to 25 microns. The finer the micron, the larger the opening area provided by the pure oblique hatching pattern. When sintered and combined, the random matrix can provide:
High flow rate: up to 20 times of other media types long lasting.
Can be reduced in size (less filtration area required to filter the same volume)
·Low pressure drop:Even at high filtration rates, the high porosity of our metal fiber media can achieve very low pressure drops (thus reducing energy costs)
· Ease of cleaning: The open structure of the porous metal media allows you to clean in situ by backflushing or backflushing
·High strength:The sintering process can form a strong fiber bond and ensure a high-strength filter medium. Combined with a proper inner core, our filter elements can withstand thermal shock, high pressure and frequent back pulses.
·Heat & corrosion resistance: Our filter media can be used in high temperature (up to 1000°C, depending on the alloy) and/or corrosive applications-where non-metallic textiles, ceramics or polymer products are unqualified
·Can be used for surface or depth filtration.Our filter media enables you to achieve high efficiency through cake accumulation (surface filtration), and also provides high dust holding capacity for deep particle capture (depth filtration).
·Stainless steel and other alloys available: Not brittle, can be chemically cleaned, can be welded, low thermal expansion, maintaining structure (no thermal shock) According to your required performance, we select the appropriate alloy to provide the required electrical resistance and strength.
For filtration, the absolute filter ratings are:
For liquids-1 to 80 µm
For air and gas—may be less than 0.1 µm (HEPA, ULPA)
3.Features of sintered metal felt filter media
· High heat and corrosion resistance: Work temperature resistance can reach 1000 °C, and stainless steel or alloy for corrosive application, which non-metallic textile, ceramic or polymer product can not compete.
· High porosity: It performs with up to 85% high porosity, long on-stream lifetime, high flow rates.
· Low pressure drop: The high porosity allows a very low pressure drop, lower energy cost at the same time.
· Depth filtration: It enables you to achieve high efficient result through surface filtration and its high dirt capacity offers depth particles capture.
· Enhanced gel removal: Addition of metal fiber felt enhances gel removal property of sintered filter media and eliminates fiber breaks during spinning.
· Longer life: Stainless steel fiber felt is added into sintered filter media, onstream life can be increased by a factor of two to three times that of conventional wire mesh media.
