The most common mistake when buying a cardboard shredder is choosing by price or by the biggest number on the spec sheet. In practice, the machine that works is the one that matches three things: the boxes actually generated on site, the output form the packing bench actually uses, and the power available in the building. Everything else is secondary. Aircosan builds a range that spans desktop, industrial, and strip-cut models, and walking through the differences is the fastest way to see where a given operation fits.
Start with volume and space. Desktop models are designed for small packing stations, e-commerce studios, and low-output environments. Cutting widths run from 350mm to 550mm, speed is 10 m/min, and cutting thickness is up to 10mm, covering three to five layer corrugated board. Power is 200W or 400W at 110V or 220V. The larger desktop units use a ZD brand geared motor and are rated for 8 to 10 hours of continuous working time. Net weight ranges from roughly 29kg to 45kg. These machines sit beside the packing table, run quietly, and plug into a standard outlet.
Floor-standing industrial models are built for higher throughput. Cutting widths start at 550mm and go up to 900mm and 1200mm. Cutting thickness reaches 15mm or 20mm depending on the model, and cutting speed reaches 18 m/min with variable frequency speed control. Power ranges from 1500W to 5500W. Net weight ranges from around 140kg to 715kg. Warehouses, logistics centers, and manufacturing plants with stable, predictable packaging volumes are the typical users.
Strip-cut tabletop models occupy a specific niche. They cut used boxes into long, narrow paper strips rather than mesh. Cutting widths are 350mm, 450mm, and 550mm, speed is 10 m/min, and cutting thickness is up to 10mm. Power is 400W, and the ZD brand geared motor supports 8 to 10 hours of continuous work. Net weight ranges from about 34kg to 45kg.
The next question is output type, and this is where most buyers need the most guidance. A strip-cut machine produces long strips with high density and strength that are easy to control, which suits wrapping, separating, and basic void fill. A perforating machine cuts patterns into the cardboard so it stretches and expands into a three-dimensional structure, and that output is thicker and absorbs impact better, so it is usually used for fragile or irregularly shaped products. Neither is better in the abstract. The choice depends on the packaging need, not just throughput. Businesses shipping light goods on high-speed packing lines are often better served by strip cutting, while operations handling fragile items may need perforation.
Within the industrial range, the models differ in ways that matter day to day. The P50 cuts fastest at 18 m/min and handles single sheets up to 15mm, which suits high-volume single-sheet processing. The P50-3 matches the P50 configuration but shreds a 550mm board into three equal pieces in one pass, with customizable cut width and quantity, and this function can be applied across the Aircosan range. The P50-X uses two sets of cutter shafts to produce honeycomb mesh and strips simultaneously, so mesh wraps and strips fill, covering two needs with one machine. The P80 handles up to 20mm and can take a whole box without separating it into single sheets, which saves labor. The P90 and P120 both handle 20mm and take two sheets of cardboard directly, with 900mm and 1200mm cutting widths respectively, suited to oversized boxes.
Power is a practical detail that catches people out. P50, P50-3, P50-X, and P80 support single-phase 110V or 220V as well as three-phase 380V. P90 and P120 support only three-phase 380V and cannot be connected to single-phase power. Factory power conditions differ, so this should be confirmed during model selection rather than after delivery.
Underneath all of these models is the same core component, and it is where the real difference between suppliers shows. Aircosan cutter shafts are large, one-piece units rather than the thin blades common on the market, designed for a service life of over five years and processed through lathe machining, high-frequency treatment, quenching, blackening, and multiple other steps. The material is 40Cr rather than ordinary 45# steel. Both need hardening, but 40Cr has lower brittleness and stronger impact resistance, and its machining time is more than twice that of 45#. At the same 550mm width, Aircosan shafts are visibly larger and thicker than competing units, cost about 30% more, and the difference shows in overall machine weight. Some suppliers use thinner shafts that deform or break above 7mm.
The engineering barrier is width. The wider the shaft, the more complex the forces acting on it, and deformation becomes a real problem. Producing shafts above 500mm is difficult. Aircosan produces 550mm shafts stably and reaches 1200mm on the P120. At present, essentially no peer on the market produces equipment this wide. That capability comes from running an in-house parts processing factory, controlling part quality directly rather than assembling from mixed outside sources.
Practical design details also carry across the range. Side sheet metal fits tightly with no gaps, so paper dust cannot enter the gears and cause abnormal noise or long-term wear. Overload protection automatically cuts power and stops the machine when a jam occurs, protecting the motor. Many machines on the market lack this, and a jam can burn out the motor while the shaft is stopped. The machines use branded motors with ample power, so thick and hard cardboard feeds smoothly without repeated jamming at the inlet.
Cardboard compatibility follows consistent rules. Most machines handle standard corrugated cardboard, including single-wall and some double-wall. Clean, dry cardboard cuts and expands best. Light tape and labels are acceptable, but staples, metal inserts, and reinforcing materials must be removed. Material that is too wet, heavily contaminated, or laminated hurts performance and wears the blades faster.
There is a regulatory dimension that has moved from background to foreground. On August 12, 2026, the core provisions of the EU Packaging and Packaging Waste Regulation fully entered into force, and the older Packaging and Packaging Waste Directive was repealed. The EU has moved to ban plastic products, and more countries are adopting similar measures. Waste cardboard disposal is also a hard cost in many markets, with fines for improper disposal and no payment for material delivered to collection points. A shredder addresses both at once: it reduces what goes out, and it produces material that replaces purchased plastic filler. The output is biodegradable packaging and degradable packing material, a practical alternative of plastic packing materials, and it supports reuse cartons and paper recycling.
Aircosan supports the full range with an after-sales team that responds within 12 hours and connects customers directly with engineers rather than routing through sales. The company supports logo customization from one piece and color customization from ten pieces, which is practical for distributors building their own brand. Products carry CE, ROHS, and UKCA certifications and hold an exclusive EU patent.
The clearest way to choose is to work backward from the packing bench. Count the boxes generated in a day, measure the largest common box, note the thickest cardboard, check the available power, and decide whether the bench needs strips, mesh, or both. Once those answers are on paper, the model selection becomes straightforward.
