PURest® Air Dryer

The Haldex PURest® is designed to enhance efficiency and extend the service life of your air brake system. Using the successful combination of the integrated multi-treatment cartridge and a large purge volume removes up to 99% of the contaminatnts in the air system and eliminates the need for a separate purge tank.  In addition, the PURest extends the life of the desiccant and allows for better recovery from the high-duty cycles.

One of the most unique features of the PURest is its universal mounting bracket, enabling easy installation or retrofit when replacing the Pure Air Plus, in addition to most competitive AD and SS type dryers.
