Collection: Autofeed Paper Shredders for High-Volume Use
An auto-feed shredder has a lidded tray that holds a stack of paper and works through it on its own. You load it, close the lid, and walk away. For offices where shredding is a task people avoid, this is usually the feature that gets it done.
Auto-feed machines quote two capacity figures, and they are not interchangeable. The tray capacity — 150, 300, 550, 600 or 750 sheets depending on model — describes unattended throughput. The manual-slot capacity, typically 8 to 10 sheets, is what you get when you feed by hand for stapled or folded documents that the tray will not take. Both numbers belong in the comparison.
The range here covers the GBC AutoFeed+ family from 150X up to 750X, the Fellowes AutoMax series, the HSM SECURIO AF line and Dahle's ShredMATIC models, at P-4 and P-5. Bins run from about 11 to 37 gallons, so match the bin to the tray: a 600-sheet tray emptying into a small bin simply moves the interruption from one place to another.
Auto-feed trays dislike staples, paper clips, folded sheets and glossy stock — use the manual slot for those. For the specification definitions behind these figures, see the specifications reference, or compare models on the comparison page.
