Desiccant Air Dryers

Desiccant air drying entails running moisture saturated compressed air over a bed of desiccant – typically made of activated alumina. During regeneration moisture is purged from the desiccant bed using the compressed air. Moisture adheres to the surface of the desiccant. Heated dryers use heat and ambient air instead of compressed air to regenerate.


The energy efficiency of the types of desiccant dryers varies based on purge air consumption. Typically, blower purge is 2.5%, heated is 7%, and heatless 15%.

Other Dryers

Membrane Dryers 


Cost effective, point of use dryers from:





SPX Hankison Breathing Air Dryers

CBA series handles removes contaminants to meet OSHA, CGA, ANSI, and CSA breathing air standards.

  • Flow rates from 15 – 940 scfm

Vacuum Dryers


Pure-Aire’s Z Series Vacuum Purge Regenerative Dryer sets a new standard in energy efficiency, with less than 1% purge lost

  • -40°F or better dew point


Filtration is essential to protect equipment and product quality.  It also plays a vital role in saving energy with reduced pressure drop from correct sizing and maintenance.



Durable and reliable element construction.  Types of filtration include:  F & FR particulate, H and HR high efficiency coalescing, C vapor removal, HP high pressure, HT high temperature, and U ultra filter.  Available threaded and flange inlet. 

  • Superior filtration 1 micron to .01 micron
  • 25 to 17,700 scfm
  • 15 to 725 psig
  • 36°  F to 350° F 

Mist Eliminators

Mist eliminators protect production equipment from extreme failures and against slugs of oil or compressor air/oil separator failure.  They are a good fail safe protection with very low pressure drop and long service life.

Condensate Management

Oil water separators-  Air systems generate condensate that contains a combination of water, oil and other contaminants.  These contaminants must be properly contained and disposed of.


Oil Water Seperators


SP – Oil Water Separators

SP – Oil Water Separators - Engineered molecular filtration attracts and holds the contaminants, while wastewater passes through.  Performance guarantee of less than 10 ppm oil carryover.

Additionally, Blackhawk Equipment oil water separator options from these manufacturers:










Drains- Remove condensate from compressors, dryers and filtration.  They key is minimizing valuable compressed air loss.  Drains often pay for themselves in less than a year.

Electric and pneumatic options to meet all sorts of applications including high and low pressure, high temperature, older systems containing rust and debris.
