Desiccant Compressed Air Dryers

BPA Blower Purge Twin Tower Dryers

The nano BPA Blower Purge Twin Tower Desiccant Compressed Air Dryers are effective in removing water vapor from your compressed air, thus reducing the pressure dew point up to -40°F. As the size of your compressed air system increases, minimizing purge air consumption becomes more crucial. The BPA range is designed to do just that, with an average purge rate of 1 to 2%, which conserves compressed air and results in significant cost savings.
