With a continuous-duty motor, this heavy-duty shredder offers a professional, data security device for a midsize busy office. Use to shred paper, staples, paper clips, credit cards and CDs/DVDs. Shredder shreds 30 sheets of 20 lb. paper at 24' per minute into 1/4" strips (security level 2). Two solid steel, cutting cylinders are subject to practically no wear and no sharpening and are made with a laser-cut and special heat-treating process for a more precise cut. Patented, V-TEK cutting-groove technology creates higher cutting capacity with lower power requirements. WhisperShred Technology reduces decibel levels so you experience a low noise level (64 decibels) whether running idle or shredding paper. Totally enclosed gear box helps reduce noise and prevents failure from dust and debris getting into the gears.
