Watts FluidAir R35-01C Pneumatic Pressure Regulator

Description:

The Watts FluidAir R35-01C Pneumatic Pressure Regulator is a 1/8 inch NPT compact air regulator designed to provide accurate and stable downstream pressure control in compressed air systems. It automatically reduces incoming air pressure to a controlled outlet pressure, helping protect pneumatic equipment and ensure consistent performance. Commonly installed in automation systems, instrumentation panels, pneumatic control circuits, laboratory equipment, packaging machinery, and OEM applications, it is ideal for installations where space is limited and reliable air pressure regulation is required.

Applications:

The Watts FluidAir R35-01C is widely used in compressed air distribution systems, industrial automation equipment, air-operated tools, process control panels, material handling systems, packaging equipment, laboratory instrumentation, and manufacturing facilities. Its piston-operated design provides high flow with low pressure drop, helping maintain stable operating conditions for downstream valves, cylinders, actuators, and other pneumatic components while improving system efficiency and reliability.
