Mesh Filter

Metal filters are predominantly utilized in commercial, industrial, and OEM applications. In some scenarios, their primary function is to protect downstream equipment from particulate contamination. In other cases, they serve to separate or screen one material from another. Whether your application involves removing unwanted contaminants from liquids or air, safeguarding costly process machinery, or simply isolating one substance from another, Hanrun can produce a custom metal filter to meet your exact specifications using wire cloth, perforated metal, or expanded metal.

Depending on region and industry, metal mesh filters may be referred to as:

Metal Wire Mesh Filter – Emphasizes the woven wire structure.

Wire Mesh Filter – A simplified term commonly used in industrial catalogs.

Wire Screen Filter – Often used in filtration equipment specifications.

Mesh Cartridge – Refers to cylindrical or preassembled filter elements.

Filter Mesh Panel – Applied in sheet or panel form for liquid or air filtration.

Advantages of Metal Filters

Metal filters are particularly well-suited for applications involving continuous exposure to liquids or moisture, or where paper filters lack sufficient strength and rigidity. Beyond their exceptional durability, metal filters offer several design advantages. They can be fabricated through welding and crimping, eliminating the need for adhesives or epoxy. Unlike paper filters, metal filters can tolerate temperatures above 500°F and withstand very high differential pressures.

The choice of metal determines chemical compatibility. For instance, stainless steel filters provide excellent resistance to corrosion in harsh or caustic environments. Another key benefit is that metal filters are cleanable and reusable. This reusability extends service life compared with paper or cloth filters, making them ideal for applications such as metal cutting, engine and compressor oil filtration, and wastewater treatment.

Metal Filter Construction Methods

Metal filters are primarily manufactured from three materials: wire cloth, expanded metal, and perforated metal. Each material has unique flow characteristics, making it suitable for specific engineering requirements. For example, perforated metal can be produced with round, square, or custom-shaped holes depending on the size and shape of the particles to be filtered.

Expanded metal and perforated metal filters provide superior rigidity and durability compared to wire cloth. However, for applications requiring intricate bends, pleats, or fine mesh ranges (from 2 x 2 up to 5 microns), wire cloth filters are typically the preferred solution, offering precise filtration performance where durability is less critical.
