The Kobra Compactor C-500 is an optional accessory designed to work with the Kobra Cyclone industrial shredder when paper is being shredded. When shredding other materials, you simply remove the compactor and use standard Cyclone disposal bags. The Kobra Compactor C-500 compress and reduces the volume of the shredded paper by 4 to 5 times to minimize the space required for disposal. Easy to install and operate, it works with any Cyclone security level screen.
