Quincy Desiccant Air Dryers purify compressed
air by absorbing water vapor. The units direct the flow
of wet compressed air through a bed of highly adsorbent
desiccant.
Only Quincy Air Dryers have “Q-Sorb”—the
first significant improvement in activated alumina in many
years—as the adsorbent desiccant. The uniform size
of its beads minimizes channeling and allows more efficient
use of the entire dryer tower, thus reducing operating
costs. Q-Sorb’s higher crush strength and low abrasion
characteristic also add to Quincy desiccant dryer performance
as they reduce dusting, which results in longer filter
element life, longer desiccant life and lower pressure
drop—all money-saving features.
