Environmentally friendly, the OFC4 Oil Filter Crusher is powered by Herkules proprietary Air-Bag technology, a virtually maintenance-free, highly durable power source. Manufactured in the USA, the OFC4 is a workhorse with 18 tons of crushing force, reducing an oil filter’s size by up to 80%. The OFC4 crushes up to 4 regular filters a cycle, or a single tall (up to 20”) heavy duty filter in a crush cycle of 35-55 seconds. The OFC4 removes up to 98% of the residual oil, with the extracted oil drained through an outlet for easy collection. Equipped with dual door/latch interlock safety system, the OFC4 is 100% air operated.
