Abstract
An oil filter crushing apparatus includes a frame on which is mounted a filter platform configured to receive a used oil filter for crushing. An air spring actuating device is secured within the frame, and a ram is secured to a lower end of the air spring. A control valve regulates the flow of a pressurized gas into the air spring which then forces the ram toward the filter platform to crush the filter. A safety pneumatic circuit prevents inadvertent actuation of the ram.
