Most warehouses receive cartons that fit within a meter. A smaller number receive cartons that do not, and that smaller number is the reason the industrial cardboard shredder page lists models at 900mm and 1200mm.
Start with what happens when a wide carton meets a narrow machine. The carton is fed at an angle, or folded, or cut down before feeding. Each of those steps takes time, and each of those steps introduces a risk, because a folded carton can jam and a cut carton produces offcuts. The page describes the wider models as being for scenarios that often handle large boxes and pursue high throughput, which is the description of a warehouse that has stopped folding.
The second part is the width. The P90 is 900mm and the P120 is 1200mm. The page describes 55cm as suitable for workstations with limited space and smaller box specs, 90cm as covering most medium boxes, and 120cm as prepared for scenarios that often handle large boxes. That sentence is a map, and the map tells the buyer where the warehouse sits.
The third part is the claim behind the 1200mm. The page states that the wider the shaft, the more complex the forces and the easier it deforms, and that above 500mm is itself a technical barrier. Reaching 1200mm is described as a comprehensive test of machining precision, material performance, and process control. The page adds 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 claim is about the factory, and the factory is why the width is available.
The fourth part is the weight. The P90 is 504kg and the P120 is 715kg. Those numbers are the shaft and the frame, and they are the reason the wide models are floor-standing rather than desktop. A wide shaft at a light weight is a shaft that deforms, and the page describes the consequence of thin shafts above 7mm.
The fifth part is the power. The page states that P90 and P120 only support three-phase 380V, not single-phase connection. A warehouse that needs the width also needs the power, and the power check comes before the width check.
The sixth part is the space. The P90 is 1276 by 705 by 1048mm and the P120 is 1524 by 734 by 1116mm. Those dimensions are the footprint, and the page notes that floor-standing packaging machines need additional floor space for safe feeding and material handling, but no dedicated room or structural modification. The warehouse has to have the space before it has the machine.
The seventh part is the demand. A warehouse that receives a wide carton once a week does not need a 1200mm machine. A warehouse that receives wide cartons every day does. The page describes the scenario as often handling large boxes, and the word often is the deciding word.
What the page does not say is that the widest machine is the best machine for every warehouse. It says the wide models exist for a specific scenario, and the scenario is the carton, not the ambition.
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 count the cartons wider than a meter in a normal week. If the count is a handful, the 900mm covers it. If the count is a stack, the 1200mm is the fit.
