Watts FluidAir MA125-160R Pneumatic Regulator

Description:

The Watts FluidAir Midi-Series Pneumatic Regulator is a compact air pressure regulator designed to provide accurate and reliable downstream pressure control in compressed air systems. Featuring a 1/4-inch NPT port connection, manual adjustment knob, and an integrated 0–160 PSI pressure gauge, the regulator maintains consistent outlet pressure despite fluctuations in supply pressure and airflow demand. With an adjustable pressure range of 0–125 PSI, the Midi-Series regulator is ideal for pneumatic automation equipment, air tools, process control systems, and industrial machinery requiring stable air pressure for optimal performance.

Applications:

The Watts FluidAir Midi-Series Pneumatic Regulator is commonly used in manufacturing facilities, pneumatic control panels, automation systems, packaging machinery, assembly lines, air-operated tools, instrumentation systems, material handling equipment, process control installations, and compressed air distribution networks where precise air pressure regulation is required to improve equipment performance, reduce component wear, and maintain consistent system operation.
