The Oil Skimmers Model 6V oil recovery system removes animal, vegetable and petroleum-based oils, fats, greases, and oily wastes that float on the surface of water. The unit removes as much as 100 gallons of waste oil per hour and decants it into a drum—so efficiently that the recovered waste oil is virtually water-free. The system uses a specially formulated collector tube. Oil adheres to the outside of the closed-loop tube as it is slowly drawn across the surface of the water and into the oil skimmer. The tube snakes over and around floating debris, adjusting automatically to changing water levels. The tube is drawn up into the oil skimmer and through scrapers that remove the oil. Then the tube returns to the water surface to collect more oil. The recovered oil flows into a collection container.
