Hankison Air Dryers and Filters

Hankinson Air Dryers

RNP Series - Non-Cycling Refrigerated Air Dryer

Non-Cycling Refrigerated Air Dryer

Curtis/Hankinson combines reliability, cutting-edge design, and innovative packaging to supply the best air treatment package in a space saving unit. The air quality delivered from a CNC Series dryer will define the difference between moderate and superior results from your plant’s processes or systems.


RNP Series non-cycling refrigerated air dryers are engineered to benefit you for a lifetime. Quality components and engineering excellence are bonded together to ensure you of a stable 38°F pressure dew point.

  • 10-3,000 scfm
  • Ensures 38°F dewpoint
  • Four levels of controllers

RDS-1 Series - Cycling Refrigerated Air Dryer

Cycling Refrigerated Air Dryer

The RDS-1 Series cycling refrigerated air dryers feature a load matching design which saves you money and reduces your costs. Featuring standard built-in air filtration and no-air-loss condensate drains ensures these dryers are a great choice for your compressed air drying needs.


The RDS-1 Series refrigerated dryer automatically cycles the refrigeration compressor on and off in response to inlet load conditions. As the inlet air load is reduced, the refrigeration compressor cycles off, providing you with the ability to reduce energy and costs.

  • 90 - 675 scfm
  • Energy Saving
  • ISO 8573.1 air quality built-in

RDS-2 Series - Digital Scroll Refrigerated Dryer

Digital Scroll Refrigerated Dryer

The energy saver RDS-2 Series digital scroll dryer is unlike any energy efficient compressed air dryer technology on the market.


Challenges for energy efficiency and dew point stability are answered with a technological breakthrough in energy efficient refrigerated air dryer design in the RDS-2 Series. Curtis/Hankinson continues the tradition of providing energy saving solutions to help you increase profits and reduce power costs.

  • 800-3,000 scfm
  • Energy efficient, digital scroll technology
  • 38°F dew point stability

Hankinson Filters

CAF Series - Compressed Air Filter

Compressed Air Filter


CAF Series filters maximize filtration efficiency through their two-stage, inside-to-outside air flow design.This innovative design ensures long element life while stainless steel inner and outer cores add structural integrity.

CAF Series filters provide your compressed air system with premium quality filtration against solid particles, condensed water droplets ad liquid oil and oil vapors.

Solid particles come from ambient air contaminants like dust and from rusted, oxidized pipework. These particles cause pneumatic equipment to malfunction, instrument and control failures, and contaminate end products.

Condensed water droplets come from the humidity in ambient air. This moisture will oxidize pipework and pneumatic equipment and also ruin paint finishes.

Liquid oil and oil vapors are introduced by compressor lubricants and by hydrocarbon vapors present in ambient air. Oil-free compressed air is particularly important in food and pharmaceutical processes.

  • 20-21,250 scfm
  • Six grades of filtration
  • 300 psig maximum working pressure

CHA Series - High Temperature Air Compressor Filters

High Temperature Air Compressor Filters

Effective at temperatures up to 450°F, the CHA Series filters provide superior filtration for high temperature applications. With cast aluminum end caps and welded carbon steel housings, you can count on the superior reliability of the CHA Series.


The CHA Series removes solid particulates resulting from desiccant dust to 1 micron.

  • 100-11,400 scfm
  • 450°F maximum inlet temperature
  • Effective two-stage filter element design

CME Series - Mist Eliminator

Mist Eliminator

The CME Series mist eliminators are used to reduce energy costs and remove oil and water aerosols from compressed air systems. Incorporating superior installation flexibility and ability to increase the life of pneumatic equipment.


Protecting products and processes from contamination, helping eliminate paint appearance and adhesion problems, and keeping pneumatic instruments operating are all benefits of using a CME mist eliminator.

  • 125-3,000 scfm
  • Low pressure drop
  • Optional automatic condensate drain
