The 520 Series of air compressors and vacuum pumps are for the recovery of ozone-depleting and other refrigerants. Because the 520 is oilless, it can recover many types of refrigerants. In addition, a high single-stage compression ratio of 50:1 provides recovery rates of 5-15 lbs/min for liquids and 0.5-1 lb/min for vapor. Other features include all wetted aluminum parts, and lightweight die-cast aluminum components.
