Sinft 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.
SINFTFELT Metal Felt Filter Element Specifications
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:
Extremely high porosity (up to 85%)
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.
