What A Regenerative Dryer Is, Presented by Sahara Air Products

Virtually all free air contains water in the form of water vapor. We call it humidity.
When air is compressed to 100 psi, the water vapor is concentrated to about 8 times normal!
Water vapor is no problem in compressed air until temperatures drop and condense it into droplets of water.
Then it combines with any other contaminants present and causes freeze-ups, leaks, and corrosion.
To protect your air system from damage caused by water, you must remove enough water vapor from your compressed air to bring its dewpoint down to a temperature lower than the compressed air will encounter at any point in the system.
A good air dryer is the answer.

SAHARA Regenerative Air Dryers offer positive dewpoint suppression to -40 °F for excellent protection, even under the most difficult conditions of very low air line temperatures. Unless your environmental and operating conditions are relatively uniform, moderate, and predictable enough to suggest a deliquescent type dryer, a SAHARA Regenerative model should be chosen to assure maximum protection for the system.

To get clean, dry instrument quality air that means
trouble-free operation for your compressed air system...

Choose a SAHARA Regenerative Air Dryer to fit your needs.
