Most buyers start their search with a machine in mind. They have seen a cardboard shredder somewhere, or a supplier has sent them a quote, and they begin comparing prices and specifications. That approach skips the most important step, which is understanding what the warehouse actually needs before looking at any machine. The questions below are the ones buyers should answer first, because the answers determine which machine fits and which one becomes a problem six months later.
The first question is about daily carton volume. Not peak volume, not the busiest week of the year, but the average number of cartons processed on a normal working day. This number decides whether a desktop model or an industrial model is appropriate. Desktop models cover 350mm, 450mm, and 550mm cutting widths at 10 m/min and up to 10mm thickness, with a ZD brand geared motor rated for 8 to 10 hours of continuous work. Industrial models start at 550mm and reach 900mm and 1200mm, with cutting thickness up to 15mm or 20mm and speeds up to 18 m/min with variable frequency control. A warehouse processing under fifty cartons a day rarely needs an industrial machine. A warehouse processing several hundred needs one.
The second question is about the largest common carton. Not the largest carton ever received, but the size that appears most often. This measurement decides whether the machine needs to handle wide cartons without pre-cutting. Producing shafts above 500mm is a genuine technical barrier, and Aircosan produces 550mm desktop shafts stably while reaching 1200mm on floor-standing models. If the standard carton is 1100mm wide and the machine takes 550mm, someone has to cut every box before feeding it, which adds a step to every order.
The third question is about the thickest board. A single sheet of seven-layer cardboard on the market is generally within 9mm, and a seven-layer box is generally within 20mm total thickness. The P50 handles single sheets up to 15mm at 18 m/min. The P80 handles up to 20mm and can take a whole box without separating it into single sheets, which saves labor on operations that handle boxes all day. The P90 and P120 also handle 20mm and take two sheets directly. If the warehouse regularly receives heavy-duty cartons, the thickness capacity determines whether the machine can process them or whether the operator has to separate layers by hand.
The fourth question is about available power. Desktop models run on 200W or 400W at 110V or 220V. Industrial models range from 1500W to 5500W. 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. This is the detail that causes the most avoidable problems, because a machine that needs power the building does not have cannot be installed without an electrical upgrade.
The fifth question is about output type. Different warehouses need different protection. A warehouse shipping fragile items needs mesh that absorbs impact and fills voids. A warehouse shipping light goods needs strips that wrap and separate. A warehouse shipping a mix needs both. The P50-X uses two sets of cutter shafts to produce honeycomb mesh and strips at the same time. The P50-3 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 entire Aircosan range.
The sixth question is about the cutter shaft, because it determines how long the machine lasts. Aircosan shafts are large, one-piece units rather than thin blades, 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. 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 thinner competing units and cost about 30% more, which shows in the overall machine weight. Some suppliers use thinner shafts that deform or break above 7mm.
The seventh question is about overload protection. Aircosan machines use overload protection: when a jam occurs, the machine automatically cuts power and stops, protecting the motor. Many machines on the market lack this, and a jam can burn out a motor while the shaft is stopped. This is not a minor feature. It is the difference between clearing a jam and replacing a motor.
The eighth question is about dust control. Aircosan machines have side sheet metal that fits tightly with no gaps, so paper dust cannot enter the gears and cause abnormal noise or long-term wear. Warehouses with high carton volume produce more dust, and machines that handle dust well last longer.
The ninth question is about material input. 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 fine, 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.
The tenth question is about after-sales. Aircosan has an online after-sales team that responds within 12 hours and can connect customers directly with engineers, without going through salespeople relaying messages. The company also has a professional customer management system containing all order information. Aircosan runs its own parts processing factory, controlling part quality in-house rather than assembling from mixed outside sources. Products carry CE, ROHS, and UKCA certifications and hold an exclusive EU patent. The company supports logo customization from one piece and color customization from ten pieces.
The regulatory backdrop makes these questions more important than they used to be. On August 12, 2026, the core provisions of the EU Packaging and Packaging Waste Regulation fully entered into force, replacing a directive in use for nearly 30 years. Plastic bans are spreading, and for warehouses still using large amounts of plastic filler, switching to paper-based cushioning is a question of when rather than whether. The output from a cardboard shredder is biodegradable packaging and degradable packing material, a practical alternative of plastic packing materials, and it supports reuse cartons and paper recycling.
For a warehouse manager, the practical approach is to write the answers to these ten questions on one page, then compare machines against those answers rather than against each other. The machine that fits the answers is the one that works. The machine that fits the price is the one that gets replaced.
