Fast and reliable fixed connection The compressed air filter provides a fast and reliable fixed connection with installation accuracy. Efficient removal of water and solid particles Designed for efficient removal of water and solid particles, practical and dependable for confident operation. Use scenarios In automated production lines that require continuous oil lubrication without interrupting the air supply. In compressed air systems where drainage mode needs to adapt to process conditions, using manual, differential pressure, or automatic drainage as needed. In workshops or industrial settings with pneumatic tools, where a reliable fixed connection and clean air ( of moisture and debris) improve performance and tool life.
