High volumes of standard sized cardboard and wood products require extra processing for maximized compaction and efficient operations. The ripper shaft both feeds and pre-shreds wood and cardboard to eliminate bridging and reduce particle size. Cardboard, pallets and crates are no match for the performance of Komar single-screw with ripper feeder augers. Maintaining the same high quality standards as their single-screw auger counterparts, the addition of the ripper feeder shaft enhances the output.”
Designed for industrial-grade challenges. Made with heavy-duty materials for long-term performance you can count on.

“Our facility is a 110,000-square-foot operations center for Goodwill of Southwestern Pennsylvania. We get between 1.2 to 1.5 million pounds of material a day, and tonnage increases significantly during the summer. The Komar auger has increased daily soft trash, wood pallets, and general trash efficiency by 30% and 40% with furniture. I love to give shock-and-awe tours to show off the Komar Auger, which compacts 8.5 to 9 tons into each payload.”
Bob Kagle, Director of Retail Logistics, Goodwill of Southwestern Pennsylvania
“Since installing our Komar Auger, we have improved our operations tremendously. The auger units have reduced labor from six people down to one person, who oversees the conveyor lines and compactors. We have gone from a 2-ton payload to a 10-ton-plus payload, per 40-yard container, reducing our annual pull charges by over 75%. We have less downtime and have eliminated jams due to the slow operation of the old compactors. Best of all, we had less than a one-year return on investment.”
John Hefty, Operations Manager, GameStop
“We estimate that the Komar Auger has saved us 1,300 hours of labor per year, has reduced our hauling cost by two-thirds, and has given La-Z-Boy a safer process and more floor space.”
Troy Kvingedal, Facilities Supervisor, La-Z-Boy
“Our disposal costs have dropped, which at least covers the cost of the compactors. Aside from the monetary aspect, the compactors allow the stores to be considerably cleaner. Cleanup at night is much easier because we have no trash cluttering up the back room of the store. All in all, we are very pleased with the compactors.”
Doug Gehrig, CEO, McDonald’s of Southwest Louisiana
Most single-screw auger compactors deliver excellent performance for common waste streams like cardboard, plastics, and general packaging. But some materials demand more than standard torque and feed capability. That’s where a ripper shaft makes the difference.

Our solutions are tailored to meet the unique needs of a wide range of industries, including:
This equipment is designed to efficiently process high volumes of wood and cardboard waste. This includes wood pallets and crates, assembled OCC, flattened OCC, and other materials that could create bottlenecks in other material handling machines.
As items enter the system, the ripper feeder feeds, tears, and pre-shreds materials, breaking pieces down into a more manageable size for a more consistent flow and denser compaction.
Thanks to precision machining, sealed bearings, and an automatic lubrication system, routine maintenance is minimal and focused on inspection rather than frequent service. Komar also offers preventative maintenance programs to help keep equipment operating reliably over the long term.
Hand loading, forklift, tipper, conveyor, and chute feeding are all supported. The system works with the loading method that fits your operation.
The main difference between the AF-4020G/W and AF-6040G/W models comes down to processing capacity and power. The 4020 handles moderate volumes efficiently, while the AF-6040 handles larger loads and heavier materials. “G” indicates a general configuration and is suitable for cardboard. Models with a “W” designation are purpose built to handle the challenges that come with wooden waste streams.
Standard pallets and crates are handled with ease. The ripper feeder shaft expands capability for longer pieces.
We are a waste solutions company. With a wide array of application-specific models and advanced engineering capabilities, we look forward to guiding you to the best solution for the job.

Most single-screw auger compactors deliver excellent performance for common waste streams like cardboard, plastics, and general packaging. But some materials demand more than standard torque and feed capability. That’s where a Ripper Shaft makes the difference.
A ripper shaft is designed to break down or pre-shred rigid, flat, oversized, or irregular items before they enter the compaction chamber. This upgrade is ideal for:
The ripper shaft integrates with the auger system to tear, puncture, and pre-shred material. This controlled breakdown improves feed consistency, minimizes stoppages, and enhances overall compaction efficiency.
If your operation handles long or smooth pieces, laminated packaging, large gaylord flats, or other difficult materials, a single-screw auger with a ripper shaft offers a practical, long-term solution. It combines the simplicity of a single-screw design with the added capability to manage complex waste streams more efficiently.
