Paper shredder for documents. The shredder processes paper using two rollers. It features a pull-out collection bin with a viewing window for the shreds. With automatic start and stop function as well as overheating protection. Particle cut, security level 4. Sheet capacity: 12 pages, 15 l collection volume. Cut output: 4 x 40 mm. The particle cut offers high security for home office or office use. In particle or cross-cut mode, documents are cut both lengthwise and crosswise. The size of the resulting particles determines the security level and the intended use of the device. Compared to a strip-cut shredder, the particle cut provides higher data security, as reconstruction is more difficult. Additionally, the particles take up less space in the waste bin because they are more compact. A device with particle cut is ideal for home and office when data security is particularly important. Security level 4 for especially sensitive data - reproduction is only possible with extraordinary effort. Security level 4 according to DIN 66399 is mainly suitable for particularly sensitive data of protection classes 2 or 3. The shredder is suitable for strictly confidential personal or company-related data such as evaluations, reports, or financial documents. Reconstruction of documents at security level 4 is only possible with extraordinary effort and corresponding knowledge.
