With maintenance-free operation and precision-milled cutting cylinders, the 50564 Oil-Free Department Shredder provides a practical solution for high-volume shredding in busy offices. It can continually shred large quantities of paper into 1/8" x 1-9/16" particles with a chain-driven motor for slip-free performance. This P-4 shredder features a large waste bin (45-gallon) for high shred capacity and less frequent bag changes. With Trident Grip jam protection, unique cylinders continuously grip paper in three places, pulling it through evenly and cleanly. Built-in, Automatic Jam Protection lets you avoid downtime and service calls. SmartPower Energy Management reduces power consumption and saves on electrical costs. German-engineered, mobile shredder also offers 16" feed width, 54-decibel operation, 22 to 24-sheet capacity, lockable casters and the convenience of automatic on/off and bag-full auto off. This machine can shred CDs, staples, paper clips and credit cards.
