Regenerative Desiccant Adsorbent Air Purifier – Aircel Oilfreepac
The Aircel Oilfreepac Purification System (50 – 5,000 scfm) removes water, oil and dirt particles from your compressed air in one process for clean, oil-free and odor-free air. It is an efficient and reliable heatless compressed air purifier providing an outlet dewpoint of either -40°F or -100°F (Optional). The Oilfreepac system filters oil and adsorbs oil vapor so thoroughly that the residual oil content is below normal detection limits, 1000 times more pure than the normal atmospheric air that we breathe.

Compress air enters the system through a Submicron coalescing filter (1) that removes the particles and the condensate mist to less than 0.01 ppm. The condensate is removed by a zero airloss drain valve (2) and exits the system (B). The air enters the heatless adsorber through the lower Automatic Piston Valve (APV) (3). The air passes through the inlet air diffuser (4) into the adsorbent bed (5) where the moisture and hydrocarbon vapors are removed.
The compressed air then passes through the outlet flow diffuser (6) and APV (7) into the final filter (8) where residual oil vapors and adsorbent fines are removed. The clean and oilfree air leaves the purifier and enters the distribution system (C) through the outlet valve (9).
The outlet air quality is continuously monitored with a hydrocarbon detector (10) and in the event that excessive levels of oil vapor are detected, the outlet valve is automatically closed and the system alarm is activated.
While one adsorbent vessel is purifying the compressed air, the other vessel is taken off line and regenerated. A partial stream of purified air is expanded to atmospheric pressure through an orifice (11) and passed through the regenerating vessel. The purging air and contaminants are exhausted to atmosphere (D) through an exhaust valve (12) and muffler (13).
When the first adsorbent vessel becomes contaminated, the regenerated vessel is put on-line and the contaminated vessel is taken off line for regeneration. The process is continuous.
