Quality Air Performance

Full Feature with built-in dryer

The Full Feature version comes with a built-in refrigerant air dryer. It cools the compressed air and removes any moisture before it can enter your compressed air network. This prevents rust in your compressed air piping and avoids damage to your air tools.

A choice of filters

To ensure your compressed air meets the quality requirements of a wide range of applications, different grade air filters can be selected:
• G 2-7: DD
• G 7L-15: DDx or PDx
• G 15L-22: DD or UD+
