TECHNICAL BULLETIN NUMBER 104 A I R & L I Q U I D F I LT E R S CUSTOM-ENGINEERED SOLUTIONS IN KNITTED WIRE MESH Metex Knitted Wire Mesh Products Solve Problems Cost Effectively Metex knitted wire mesh is manufactured from an “endless” wire that is formed into loops and subsequently networked, providing elasticity and resilience not found with woven wire or powdered metal products. The diversity and versatility of wire mesh enables Metex to produce products for a wide variety of applications, including: • Seals • Heat Wicks • Air Gap Rings • Breathers • Noise Attenuators • Filters • Coalescers • Mufflers • Shock Absorbers • Gaskets • Air Filters • Protective Coverings • Heat Shields • Electronic Shielding • Exhaust Seals • Navin Rings • Ball Joint Seal • Catalytic Converter • Catalytic Converter Systems End Rings Support Mesh • Flame Arrestors For forty years, Metex design, development, and manufacturing engineers have been producing engineered components that take maximum advantage of the unique characteristics and robust nature of knitted wire mesh. Its interlocked looped structure, which offers excellent resiliency, memory— even when subjected to high temperatures as well as high-tensile or compressive stress—and strength, make knitted wire the ideal choice in materials when both performance and cost are paramount. Metex products now meet a wide range of critical needs—from providing flexible, yet durable, seals and joints to noise attenuation, thermal insulation, and filtration—in some of the most demanding industrial applications and environments. Our Knitted Wire Mesh Filters continue a longstanding Metex tradition of integrating the right designs, materials, and manufacturing methods to meet customer needs for optimal performance at lowest possible cost.

These types of elements simply will not withstand these types of operating conditions. Since paper filters are typically composed of organic materials, they are also subject to attack by the caustic byproducts of many industrial processes— such as those involving combustion. For example, corrosion often takes place when high-temperature lubricating oils are loaded with such acids. After extended use, the surface area of the paper filter becomes heavily loaded, resulting in filter weak spots. (If the pressure relief valve is not set low enough, and the pressure is allowed to remain at normal operating pressure [500 to 700 kPa], paper filter elements may tear, fracture, or even burst.) Sintered metal filters—due to their granular construction—are also prone to fracture or disintegration when subjected to the stresses of high temperature and shock. Unless the fusion process involved in their construction is 100% complete, small particles may begin to break away. As a result, when installed on either rotating or reciprocating machinery, little particles of filter material very frequently detach and migrate to block the very devices the filter was designed to protect. Metex knitted wire mesh liquid and air filters overcome the limitations and deficiencies of these and many other filtration methods. Where resistance to degradation, corrosion, mechanical, or thermal shock is desired—and where a resilient product is needed for proper cavity fit—Metex filters provide an economical, robust alternative. From cryogenic operating conditions up to temperatures of 650° C, knitted wire mesh filters maintain their integrity even when subjected to extremely high vibration and exposed to destructive gases such H2, SO4, and HNO3.
