Some warehouses receive the same oversized cartons week after week. Furniture arrives in cartons wider than a meter. Appliances arrive in boxes that do not fold. Building materials arrive on pallets with cartons that were never designed for a bench. The product page for the industrial cardboard shredder addresses those warehouses in a sentence about the wider models.


Start with the claim. The page states that the P90 is 900mm and the P120 is 1200mm, and that the wider the shaft, the more complex the forces and the easier it deforms. Above 500mm is itself a technical barrier, and reaching 1200mm is 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. The claim is about the engineering, and the engineering is why the width exists.


The second part is the carton. A carton wider than a meter does not fit a 550mm machine without folding. It fits the 900mm machine if it is under 900mm, and it fits the 1200mm machine if it is under 1200mm. The measurement is the first step, and the page gives the range to measure against.


The third part is the power. The page states that P90 and P120 only support three-phase 380V, not single-phase connection. A warehouse with oversized cartons often has three-phase power in the loading area, and the power check is the first gate before the width check.


The fourth part is the space. The P90 is 1276 by 705 by 1048mm and the P120 is 1524 by 734 by 1116mm, and the page notes that floor-standing packaging machines need additional floor space for safe feeding and material handling. An oversized carton needs a staging area, and the staging area is part of the footprint.


The fifth part is the weight. The P90 is 504kg and the P120 is 715kg. The page uses the weight as a way to judge the shaft, and the same weight is the reason the machine stays in one place. A wide machine on a mezzanine is a structural question, and the page does not claim that the machine is light.


The sixth part is the output. The page describes the wide models as producing mesh, and the mesh is the form that suits the larger cartons. The output is biodegradable packaging and degradable packing material, a practical alternative of plastic packaging, and the material story holds across the range.


The seventh part is the certification. The page states that the product passes CE, ROHS, and UKCA certifications, and holds an exclusive EU patent. A warehouse serving export customers is asked for certifications, and the page lists them because the list is the answer.


What the page does not say is that every warehouse needs the widest model. It says the wide models exist for the cartons that need them, and the cartons decide.


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#. 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. After-sales responds within 12 hours and connects customers directly with engineers.


For a warehouse manager, the practical approach is to measure the three largest cartons, confirm three-phase power at the loading area, and check the floor space against the dimensions. Those three checks decide between the P90 and the P120.
