  • Pressure dew points as low as -40°F (-40°C)
  • Powder-painted, corrosion-resistant aluminum housing
  • Desiccant change-out indicator
  • Integrated 15 micron cleanable dust filter
  • 1/4" or 1/2" NPT connections
  • Optional HDF-F Oil Pre-filtration Package:
    • HF Series Grade 5 oil filter to 0.01 ppm (0.01 mg/m3) remaining oil content


The Hankison HDF Series Single Tower Desiccant Air Dryer eliminates that damaging water, dirt, and oil from your compressed air system. Contaminated air enters oil pre-filter housing and flows through the element from inside to outside. Water and oil condensate collect at the bottom and are drained automatically. Clean air exits the filter outlet and enters desiccant dryer housing where it flows through silica gel desiccant. When the desiccant is saturated, the indicator changes from blue to white. Compressed air then flows upwards through an integrated dust filter and into an outlet air stem, which takes it to the dryer housing outlet port.
