With the Rexel Optimum AutoFeed+ 90X P4, you can automatically shred 90 pages at a time. The DIN P-4 security standard turns a sheet into 421 shreds. Even staples, small paper clips, and credit cards are shredded in no time. If you still prefer to work manually, you can shred up to 8 sheets at a time. After 20 minutes of shredding, the Optimum Autofeed+ needs 45 minutes to cool down. And if you don't use the shredder for a while, it automatically goes into energy saving mode after 2 minutes. The 34L container has room for 250 A4 sheets. And thanks to the transparent see-through window, you can see how full the bin is right away. At only 55dB, the noise level is comparable to that of an electric toothbrush.
