100-Series Shredders

Industrial paper shredding – up to 2½ tons per hour – for 1 or 2 operators

  • Heavy duty shredding for secure destruction of paper, cardboard, and other materials
  • Designed for integration into a complete shredding system to reclaim recycling dollars and reduce labor costs
  • Excellent for centralized paper shredding services


Allegheny’s heavy duty, industrial 100-Series Shredder is the initial shredder of choice for the majority of contract paper shredding services or large institutions needing a centralized paper shredding location. If you’re starting up a contract paper shredding service, you will appreciate the extremely reliable design that has been refined and proven for over 50 years.

The 100-Series includes two models, 18-250C and 20-350C, each offering different horsepower options. An extra-wide input conveyor and powerful crusher paddle allow these machines to thoroughly shred all types of confidential materials – paper documents (thick stacks of computer printouts, file folders, waste bin contents, and even 3-ring binders full of paper!); multimedia materials (microfiche, microfilm with reels, audio/video cassettes, CDs); and plastics (x-rays, credit cards and ID badges).

As the main component in a complete shredding system, a 100-Series Shredder is often accompanied with an output conveyor, baler and HLS tipper to maximize your throughput and save on labor costs.


  • Fast, efficient shredding of large volumes of paper, cardboard, or other confidential materials
  • Unique cutting assembly with optional T-18 tool steel cutters to handle the most abusive applications
  • Ideal for large organizations that provide centralized paper shredding, or for contract paper shredding services

Optional Equipment

Allegheny offers optional equipment to provide easier disposal of your shredded materials and enable you to turn your waste paper into recycling dollars. We can even custom design a complete shredding system to maximize your shredder’s productivity and reduce your labor costs.

We’ll help you determine the most efficient way to collect materials for shredding, process materials through the shredder, and recycle shredded paper for a profit.

Allegheny will also help you design the physical layout of your system to make the most efficient use of available space and personnel. Using computer-aided design technology we can provide you with a detailed diagram showing the optimal layout of your shredding system within your facility.

Our technicians are available to install your complete shredding system and train your personnel to ensure safe, efficient operation and proper maintenance of your equipment.

Sorting Conveyors
Allegheny Sorting Conveyors allow several operators to separate materials by grade and type prior to shredding, thus maximizing the value of your recycled paper.
Used with a loading cart, security container, or a Gaylord box, Allegheny Tippers offer an efficient way to load materials onto your shredder’s input conveyor. This increases the volume of throughput to be shredded and minimizes operator fatigue and strain.
Output Conveyors
For transporting shredded materials into a baler, compactor, dumpster, or other receptacle.
