キッツマイクロフィルター List of Products and Services

This is a hollow fiber membrane filtration filter for compressed air and nitrogen. The hollow fiber membrane consists of bundles of straw-like (macaroni-shaped) fibers with hollow interiors, capturing foreign substances on the outside of the membrane and supplying clean fluid. Due to the fine pore size of the hollow fiber membrane, it achieves precise filtration accuracy. This filtration accuracy is 0.003μm (3nm). It is mainly used in sensitive environments such as semiconductor manufacturing, electronic equipment manufacturing, and food factories, where contamination by minute foreign substances is a concern. Because of its double packaging design, it can be used without issues in clean rooms. *Filtration accuracy depends on our measurement conditions. ■ Inquiries about the product - Industrial Filter Sales Department, East Japan Sales Office TEL: 03-5568-9281 - Industrial Filter Sales Department, West Japan Sales Office TEL: 06-6533-0360

■About this product This is a dehumidifying filter that separates water vapor from compressed air and nitrogen air. The separated water vapor is released into the atmosphere, so no drainage treatment is necessary. ■To achieve dehumidification effect 1. Increase the supply pressure on the inlet side 2. Increase the flow rate on the inlet side 3. Restrict the flow rate on the outlet side with a flow control valve 4. Increase the purge amount ■What is purging? Purging refers to the process of releasing a portion of the dry air supplied to the outlet side, along with the water vapor inside the membrane, to the atmosphere through a separate circuit from the outlet side (purge). - The greater the purge amount, the better the dehumidification performance, but the flow rate on the outlet side will decrease. - If the purge amount is small, the dehumidification performance will slightly decrease, but a larger flow rate can be maintained on the outlet side. ■Mechanism of water vapor separation The filter uses a hollow fiber membrane made of polyimide material, which allows water vapor to pass through easily. When humid air is passed through from the inlet side under pressure, the water vapor is separated. As a result, dry air is obtained on the outlet side. It cannot be used under reduced pressure, as the water vapor will not be separated and dehumidification will not occur.

We will be exhibiting at JASIS 2024, which we participate in every year. We will showcase our main products, including the "Humidity Control Device" that maintains a constant humidity in confined spaces, as well as our precision filtration filters. Additionally, we will hold a new technology presentation, so please feel free to stop by. ◆ Date & Venue ◆ September 4 (Wed) - September 6 (Fri) 10:00 AM - 5:00 PM Makuhari Messe International Exhibition Hall Nearest Station: JR Keiyo Line "Kaihin Makuhari" Station, about a 10-minute walk * Our booth: Hall 8, 8B-302 * Please register in advance via our website when visiting.

Air filters and air dryers used for various analytical devices such as NOx analyzers (nitrogen oxide measurement devices), atmospheric analyzers, PM2.5 automatic measuring devices, and cell analyzers, for the purpose of preventing foreign substances and moisture contamination in carrier gas, blank gas, flushing, and zero gas. By equipping analytical devices with air filters and air dryers, it is possible to prevent noise caused by the contamination of foreign substances and moisture in the supply air of the analytical devices.
