Watts B12-03DJB Filter/Regulator

The Watts B12-03DJB is a professional-grade 3/8" NPT filter/regulator (piggyback) designed for precise pneumatic pressure management in demanding HVACR and industrial environments. This unit features a robust T-handle adjustment for reliable torque and control, regulating downstream pressures within a 0-60 PSI range. Engineered for high-flow efficiency, it maintains consistent system performance while the integrated 40-micron filter element effectively captures contaminants to protect downstream components. The Watts B12-03DJB utilizes a metal bowl construction to withstand rigorous mechanical stress and is suited for high-pressure primary air supplies. Contractors favor this particular configuration for its compact FRL design, which saves critical space in control panels without sacrificing flow capacity. All technical specifications focus on maintaining a repeatable pneumatic pressure setpoint, ensuring that air-driven tools and actuators operate at peak efficiency. This integral unit simplifies installation by combining filtration and regulation into a single, high-durability housing.

• Precise Pressure Control: Accurate 0-60# regulation range for sensitive pneumatic applications.
• Enhanced Contaminant Removal: Standard 40-micron filtration prevents debris from damaging downstream valves and seals.
• Field-Proven Durability: Metal bowl and heavy-duty T-handle design built for technician-level daily use.
• Space-Saving Footprint: Piggyback configuration combines two functions into one 3/8" port body.

What is the maximum inlet pressure for this unit?
Standard B12 series units typically handle a maximum primary pressure of 250 PSIG with metal bowls, though specific system operating parameters should always be verified against the local load requirements.

Can I swap the filter element for a finer 5-micron version?
Yes, the Watts B12-03DJB allows for interchangeable elements, enabling technicians to upgrade to a 5-micron filter if the application requires superior air purity.

How do I ensure the pressure setting stays consistent?
For the most accurate performance, always set the pressure by increasing from a lower PSI up to your target 60 PSI maximum setpoint.
