QUINCY

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 air dryer performance as they reduce dusting, which results in longer filter element life, longer desiccant life and lower pressure drop - all moneysaving features.
