MettleAir® Semi-Automatic Drain filters are designed for precision and reliability. Our filters are the best choice when it comes to protecting your pneumatic investments from water, dirt, rust and other debris. All of our Semi-Automatic Drain filters are able to drain as soon as the system air pressure drops to zero. A wide range of mounting brackets allow for easy installation. The unique modular design allows for easy upgrades and maintenance. Standard 25 Micron sintered bronze filters are easy to clean and maintain. We also have optional 5 micron disposable filter cartridges available as well.
