The product page for the industrial cardboard shredder lists the cutter shaft widths as 550mm, 900mm and 1200mm, and it explains why the number is a decision rather than a detail. A warehouse that picks the wrong width either prepares every carton before feeding it or pays for capacity it never uses.
Start with the floor. The page states that Aircosan industrial models start at 550mm, and that the 550mm models are the P50, P50-3, P50-X and P80. A warehouse handling standard shipping cartons will find that most of them fit within that width. The 550mm models are the ones the page describes as supporting single-phase power as well as three-phase, which means they can be installed in more places than the wider models.
The second step is the 900mm. The page lists the P90 at 900mm, and it describes the reason the width grows. The wider the shaft, the more complex the forces and the easier it deforms, and above 500mm is itself a technical barrier. The 900mm model exists for warehouses that handle cartons that are wider than a meter on a regular basis, rather than occasionally.
The third step is the 1200mm. The page lists the P120 at 1200mm, and it describes the width as a comprehensive test of machining precision, material performance, and process control. The page also states that currently basically no peer on the market can produce equipment this wide, and that being able to make it is itself direct proof of Aircosan's hard strength. The 1200mm model is for warehouses that handle oversized cartons as a normal part of the week.
The fourth step is the carton measurement. The page does not give a rule for choosing, but it gives the dimensions that make the rule obvious. A carton wider than the cutting width has to be folded or cut down before it is fed, and that step repeats on every carton. A warehouse that measures its ten most common cartons will find the answer in the range rather than in the specification table.
The fifth step is the power. The page states that P90 and P120 only support three-phase 380V, not single-phase connection, while the 550mm models support both. A warehouse without three-phase power at the planned location cannot install the wider models regardless of the carton size, which makes the power check the first step rather than the last.
The sixth step is the footprint. The page lists the machine dimensions for each model, and the dimensions grow with the width. The P50 is 740 by 461 by 850mm. The P90 is 1276 by 705 by 1048mm. The P120 is 1524 by 734 by 1116mm. A warehouse that has the carton volume for a wide model also needs the floor space for it, and the page gives the numbers to check.
The seventh step is the output. The page notes that the 550mm models can produce mesh, strips, or both, and that the wider models also produce mesh. The output form is not the reason to choose a width, but it is the reason to choose a model within a width. The P50-X produces both at the same time, and the P50-3 produces three equal pieces, and both sit at 550mm.
What the page does not say is that the widest model is the best model. It says the widest model exists for the cartons that need it, and the buyer's cartons decide whether that is the case.
Aircosan machines use overload protection, so when a jam occurs, the machine stops automatically and protects the motor. 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. Aircosan machines use a branded motor with ample power, so thick and hard cardboard feeds smoothly without repeated jamming at the inlet. 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. Die life is generally 1.0 to 1.3 million meters depending on material and usage.
Aircosan runs its own parts processing factory, controlling part quality in-house rather than assembling from mixed outside sources. The company supports logo customization from one piece and color customization from ten pieces. Products carry CE, ROHS, and UKCA certifications and hold an exclusive EU patent. After-sales responds within 12 hours and connects customers directly with engineers.
For a warehouse manager, the practical approach is to measure ten cartons, confirm the power at the planned location, and measure the floor space beside the bench. Those three checks take an hour, and they decide the width before the invoice.
