Watts FluidAir B11-02WJC M3 General Purpose Filter Regulator

Description:

The Watts FluidAir B11-02WJC M3 General Purpose Filter Regulator is a 1/4 inch integral pneumatic filter and pressure regulator designed to remove contaminants from compressed air while maintaining controlled downstream pressure for pneumatic equipment and automation systems. Commonly installed in air compressor systems, pneumatic control panels, manufacturing machinery, packaging equipment, process control systems, and industrial automation applications requiring clean, regulated compressed air. Maintenance technicians, OEMs, machine builders, and system integrators use this filter regulator for equipment repairs, pneumatic system upgrades, replacement projects, and new installations requiring reliable air filtration and pressure regulation.

Applications:

The Watts FluidAir B11-02WJC M3 Filter Regulator is widely used in compressed air distribution systems, pneumatic automation equipment, assembly lines, manufacturing facilities, packaging machinery, instrumentation systems, process control panels, air-operated tools, material handling equipment, food processing machinery, printing equipment, HVAC control systems, OEM machinery, and industrial production environments. The integrated filter and regulator design removes particulate contamination and moisture while maintaining stable downstream pressure, helping protect valves, actuators, cylinders, and sensitive pneumatic components from damage caused by dirt, water, and pressure fluctuations. It is commonly specified in industrial plants, maintenance departments, and automated manufacturing systems where clean, regulated air is critical for reliable equipment performance, process efficiency, and extended component life.
