Watts B75-04BJC Filter Regulator

The Watts B75-04BJC Filter Regulator is a precision-engineered air preparation component designed for high-demand pneumatic systems. This 1/2" NPT filter regulator is identical to part number 1361027 and provides effective 40-micron filtration to protect downstream equipment from moisture and solid contaminants. For contractors managing airflow in industrial environments, this unit features a durable zinc body and a 3.8-ounce polyurethane bowl equipped with a manual drain. It operates with a primary pressure range of 0-125 psi and a maximum inlet pressure of 150 psi, delivering a high flow capacity of up to 80 SCFM. The 1/8" NPT gauge ports and integral mounting slots allow for a streamlined installation without the need for additional brackets. Utilizing a Buna-N diaphragm and O-ring, the B75-04BJC ensures reliable sealing and accurate regulation for consistent system performance.

Key Benefits for Technicians

• Reduced Pressure Drop: The high-efficiency 40-micron polyethylene element maximizes flow while maintaining air quality.
• Interchangeable Compatibility: Cross-references directly with part 1361027 and 1360018 for seamless field replacement.
• Rugged Housing: Zinc construction and a high-strength polyurethane bowl withstand rigorous mechanical rooms and shop environments.
• Simplified Mounting: Integral mounting slots cast into the body facilitate faster setup on equipment skids.
• Precise Control: Highly responsive regulation ensures stable output even during fluctuations in supply pressure.

Common Technical Questions

What is the maximum flow rate for the B75-04BJC?
This unit is rated for a maximum flow of 80 SCFM, making it suitable for medium-to-large pneumatic service requirements.

Can I use a pressure gauge with this regulator?
Yes, the housing includes two 1/8" NPT gauge ports. Note that the pressure gauge is sold separately.

Is this unit compatible with synthetic oils?
Because this model uses a polyurethane bowl, it is recommended for use with mineral-based oils; avoid exposing the bowl to synthetic chemicals or solvents that can degrade the material.
