Which are the most popular industrial paper shredders that can shred huge amounts of paper easily?

Many companies find they need to shred significant amounts of paper on a regular basis, while for some this is an annual concern due to tax dates or state laws. While many choose to outsource their shredding by hiring a confidential document shredding company (many of these have shredders built into their on-site trucks), buying a dedicated shredding machine can be a good investment. Some of the most popular brands of industrial paper shredders are Ativa, Industrial Shredders, and Allegheny.
