OFC Series Heatless Desiccant Air Dryers

Parker Airtek OFC Series is a heatless desiccant dryer designed specifically for oil, gas and related industries. The dryer provides instrument quality compressed air and is packaged for maximum reliability and long, trouble-free service life.

Parker Airtek's OFC Series of heatless desiccant dryers provide a continuous supply of dry, oil-free compressed air by automatically cycling the flow of air through two desiccant towers. Compressed air is dried through one tower while the other desiccant tower is being regenerated by a portion of the dried air. Cycling is controlled by a solid state controller.

Considering the importance of filtration to dryer performance, Parker Airtek recommends that all OFC Series dryers are ordered as a complete, factory assembled air treatment system. Standard equipment includes: properly sized, factory installed coalescing pre-filter and particulate after-filter with automatic float drain system and visual element condition indicators. Oversized filters are selected for longer element life and low pressure drop.
