The CP-4000 series compactors are four cubic yard heavy industrial machines designed to handle mixed waste and transfer needs. Built to last with beefy supports, upgraded components, and designs that prevent twisting and buckling, these compactors are strong enough to handle most any compaction needs. Each configuration fits the needs of specific waste streams. The CP-4001 is a single cylinder machine that handles general waste and light production debris. The dual cylinder CP-4002 and CP-4002HD handle tough to compact loads and allow you to choose the machine that will insure that each load you send to the landfill is full and meets the maximum load allowed by law thus getting the most efficiency from your waste disposal practices.
