Also known as coalescing filters, these filters are designed to capture oil and water aerosols so they can be drained from the system. They also remove dust and dirt particles. Use the indicator to monitor the condition of the filter element. A modular connector allows easy removal and replacement. Coalescing filters are often used for filtering paint spray booths, breathing air, air valves, and air cylinders and can also serve as a prefilter before an air dryer to prevent contamination of desiccants.
The smallest of filters, these miniature filters are used in low-pressure pneumatic systems where space is limited and before air tools.
