Parker Watts Fluid Air B35-02WHC Regulator

The Parker Watts B35-02WHC is a professional-grade integral filter regulator engineered for precise pressure management and contaminant removal in pneumatic circuits. Part of the rugged B35 series, this 1/4" NPT filter regulator is built with a zinc body and a 1.5 oz zinc bowl featuring a sight glass for immediate condensate monitoring. It manages a maximum inlet pressure of 250 PSI, delivering a reduced pressure range of 0-125 PSI with a 35 SCFM max flow rate. The internal 20-micron polypropylene filter element ensures clean air delivery to downstream components, while the relieving diaphragm design and Buna-N seals provide stable performance under heavy-duty cycling. Designed for easy maintenance, it includes a manual drain and dual 1/8" NPT gauge ports. This unit is essential for technicians maintaining automation equipment, manufacturing lines, and compressed air systems that demand high-flow reliability in a compact footprint.

Technical Benefits:

• Enhanced Contaminant Control: The 20-micron element captures particulate matter effectively, protecting sensitive solenoids and actuators.
• Superior Durability: Metal zinc bowl construction offers greater chemical resistance and pressure integrity compared to standard polycarbonate options.
• Optimized Pressure Stability: The relieving feature allows for pressure reduction even in dead-end circuits, preventing downstream over-pressurization.
• High Flow Efficiency: Delivers up to 35 SCFM, minimizing pressure drop across the 1/4 inch NPT porting.

Common Questions:

How do you drain the collected moisture from the B35-02WHC?
This model utilizes a manual drain located at the base of the zinc bowl. Technicians should periodically rotate the drain valve to expel accumulated water and oils captured by the filter element.

Can this regulator be used in a panel-mount application?
No, the B35-02WHC is designed for in-line pipe mounting. It does not feature the neck threading or bracket configuration required for panel installation.

Does this unit come with a pressure gauge?
The regulator includes two 1/8" NPT gauge ports (front and back), but the gauge itself must be purchased separately to match your specific system requirements.
