Air Regulators

Industrial Air Pressure Regulators

Air regulators reduce a higher supply pressure to a controlled downstream pressure and help maintain that setting despite normal inlet-pressure fluctuations. Correct pressure control protects tools and machinery while supporting consistent operation.

Choose the Correct Air Regulator

How an Air Pressure Regulator Works

Compressed air enters the regulator at the higher inlet pressure. The adjustment spring, diaphragm and valve mechanism reduce the pressure and maintain the selected outlet setting as demand changes within the regulator's operating capacity.

• Reduces supply pressure to a controlled downstream level.
• Protects air tools, valves, cylinders and hoses from excessive pressure.
• Helps provide consistent tool speed and process performance.
• Can reduce unnecessary air consumption where pressure was previously too high.
• Provides straightforward adjustment using the regulator knob.

Installation and Adjustment Guidance

• Install in the direction shown by the airflow arrow.
• Use a regulator with sufficient flow capacity for the application.
• Fit a compatible pressure gauge where accurate adjustment is required.
• Turn the adjustment knob clockwise to increase outlet pressure.
• Turn the knob counter-clockwise to reduce the setting.
• Lock the adjustment mechanism after setting, where the model provides this feature.
