The Vacuum Filter VFU is a specialized filtration device designed to remove particulates from vacuum systems where air flow is the primary medium. It ensures clean, particle-free air by capturing contaminants before they enter downstream equipment or processes, making it ideal for applications requiring high-cycle vacuum operations and consistent performance under low-pressure conditions.
The filter body is constructed from PBT resin for its main structural components, offering durability in standard environmental conditions. Critical metal parts, such as housing fittings and support elements, are made from brass with electroless nickel plating to enhance corrosion resistance and mechanical strength. For environments exposed to high levels of corrosive agents, the primary metal components are fabricated from special stainless steel, which provides corrosion resistance equivalent to SUS303.
The Vacuum Filter VFU features a range of available sizes including φ1.8, φ3, φ4, φ6, φ8, and φ10 mm in diameter. It is also available with metric female thread connections such as M3x0.5 and M5x0.8, allowing for integration into various vacuum system designs and piping configurations.
The filter operates within an air medium under a pressure range of -100 to 0 kPa, suitable for vacuum conditions without positive pressure. It is rated for operating temperatures between 0°C and 60°C, with no freezing risk. The seal materials are composed of HNBR rubber, which offers improved ozone resistance over standard NBR and is specifically selected for low-concentration ozone environments.
The VFU is available in multiple sizes to match different system requirements, including φ1.8 through φ10 mm. Threaded connections are offered in M3x0.5 and M5x0.8 configurations to ensure compatibility with a wide range of vacuum equipment. No copper-based metallic material is used in the flow path, ensuring compatibility with systems sensitive to metal contamination.
The filter integrates directly into vacuum systems via its metric female thread connections (M3x0.5 or M5x0.8), allowing secure attachment to existing piping or vacuum components. Its design supports direct installation without additional fittings or modifications, making it a straightforward addition to high-cycle vacuum operations.
