Economical and environmentally friendly, the OFC4 is powered by Herkules proprietary Air-Bag technology, a virtually maintenance-free, highly durable power source. Manufactured in the USA, the OFC4 provides 17.5 tons of crushing force, reducing an oil filter’s size by up to 80%. Efficient and environmentally-safe, the OFC4 crushes up to 4 regular filters a cycle, single tall (up to 20″) heavy duty filters in a crush cycle time of 35-55 seconds. The OFC4 removes up to 98% of the residual oil, with extracted oil drained through an outlet for easy collection. Equipped with dual door/latch interlock safety system, the OFC4 is 100% air operated, using 120 psi standard shop air, and requires little maintenance.
