The Rexel Momentum P420+ jam free paper shredder is ideal for destroying confidential documents in the office. This cross cut shredder machine shreds up to 20 sheets of A4 paper (80gsm) in one go through the manual feed slot into P4 security level (4 x 40mm) cross cut pieces. Active sensing technology measures the number of sheets being fed in real-time to stop paper jams and mis-feeds; indicated by a red LED on the control panel. This cross cut paper shredder will not operate until the number of sheets is reduced below or at the maximum sheet capacity. The Rexel office shredder is designed for moderate to heavy use with its high sheet capacity, large 30L bin size and long run time of up to 4 hours. It features a touch control panel, infra red sensing technology to alert you when the bin is full, and a 55 dBA ultra-quiet noise level.
