Watts 11F22EC Coalescing Filter Overview
The Watts 11F22EC is a Grade 6 coalescing filter designed to deliver clean, dry compressed air to downstream HVAC equipment, pneumatic controls, and air-operated devices. With a 3/8″ NPT connection, this compact inline filter is engineered for easy installation in a wide range of compressed air systems, protecting sensitive components from the damaging effects of oil aerosols, water droplets, and fine particulate contamination.
What Is a Coalescing Filter?
Coalescing filters work by forcing compressed air through a specialized filter element that causes tiny oil and water aerosol droplets to merge (coalesce) into larger droplets, which then drain away from the airstream. Grade 6 filtration provides an effective level of oil and moisture removal suitable for general-purpose pneumatic applications, instrument air, and HVAC control systems.
