Benefits

• Improves compressor efficiency and reliability
• Ensures proper lubrication during startup and operation
• Enhances oil separation performance
• Reduces energy losses and unnecessary wear
• Extends compressor service life
• Minimizes maintenance costs and unplanned downtime

Working Process

1. During startup, the minimum pressure valve keeps pressure inside the separator vessel until the required operating pressure is reached.
2. The thermostatic valve controls oil flow according to oil temperature.
3. As the oil warms, the thermostat gradually routes oil through the cooler to maintain the ideal operating temperature.
4. Once the minimum pressure is achieved, the MPV opens to deliver compressed air to the air system while maintaining efficient oil circulation and separation.

Typical Applications

• Atlas Copco oil-injected rotary screw air compressors
• Chicago Pneumatic compatible compressor models using the same service kit
