Herkules Equipment Corp. reported its oil filter crusher (OFC4) crushes multiple filters or one large (20-inch) filter, extracting up to 98% of the oil and reducing the filter size by 80% for clean, cost-efficient disposal. The OFC4, powered by air technology that is said to eliminate electrical and hydraulic hazards, produces 18 tons of crushing force with a required 120 psi. A dual door/latch interlock system is provided for operator safety. Extracted oil from the crushed oil filters flows from the chamber down to the drain outlet for easy collection, according to the company.
