Department paper shredders are great if you need to shred a large volume of paper everyday. If you have a large office or department that has high paper output you probably need a department shredder. Department paper shredders often have wider feed openings to handle the volume of documents that large offices shred. If you buy a cross-cut shredder you will need to regularly lubricate it with shredder oil. Want to view all of the shredder categories? Here is the Main Paper Shredder Page.
