Waterproof breathable filter "SBF" for sensors and electronic components.
Uses ePTFE membrane with excellent breathability, water resistance, and oil repellency. Ventilation filter "SBF" for sensors and electronic components.
"SBF" is a product designed and developed to prevent the intrusion of external factors such as dust, oil, and water droplets that can affect the functionality of precision equipment. By installing "SBF" at the external air intake (internal pressure adjustment port) of precision components, it efficiently removes impurities from the incoming air while allowing pressure and heat inside the machine to escape to the outside. Additionally, it can be customized with functions such as water and oil repellency according to the application.
