Start with the thickness row. P50, P50-3 and P50-X handle up to 15mm. P80, P90 and P120 handle up to 20mm. 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. That second number is the one that changes the workflow. A sheet fed one at a time is within the 15mm range, which is why the P50 handles it easily at 18 m/min. A whole box is within the 20mm range, which is why the P80, P90 and P120 can take it directly.
The guide explains the practical difference in plain language. A seven-layer box on the market is generally within 20mm total thickness, and the P80 does not need to separate into single sheets, so the whole box can be shredded directly. Suitable for users who often shred whole boxes, greatly saving labor and making work more efficient. The same logic applies to the P90 and P120, which also take two sheets of cardboard directly.
That sentence describes the most common hidden cost in a packing operation. Separating a box into single sheets takes time on every box, and that time is invisible on a specification sheet but visible in the labor hours after a month. A machine that removes the separation step removes that labor, and the saving is proportional to the number of boxes handled per day.
The layer row supports the same reading. Applicable paper is listed as three to seven layers across all six models. The range covers standard shipping cartons and the heavier boxes that arrive with industrial goods. Boards outside the range are not suitable, and the page is clear about that in the FAQ. Most cardboard perforators can handle single-wall and double-wall corrugated cardboard, a small amount of tape and labels is usually acceptable, but excess staples or reinforcement materials must be removed. Cardboard moisture content also matters, dry cardboard improves output efficiency and reduces wear on cutting components.
There is a third row that connects to the other two, which is the speed. P50 reaches 18 m/min, P80 reaches 15 m/min, and P50-X, P90 and P120 reach 12 m/min. The slower speeds on the thicker models are not a limitation. They reflect the trade-off between speed and thickness. A machine cutting a whole box at 15 m/min is doing more work per minute than a machine cutting a single sheet at 18 m/min, because the input is heavier. Reading the three rows together is what shows the real throughput.
What the table cannot show is the cut quality on thick board. 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 when cutting above 7mm. The shaft is the component that makes the 20mm thickness row real rather than theoretical.
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. Die life is generally 1.0 to 1.3 million meters depending on material and usage.
The output is biodegradable packaging and degradable packing material, a practical alternative of plastic packaging. It supports reuse cartons and paper recycling. 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 packing supervisor, the practical approach is to measure the thickness of the most common box on the line with a caliper. If the answer is under 15mm and the box is fed as a single sheet, the P50 is the efficient choice. If the answer is close to 20mm and the box is fed whole, the P80 or above is the choice that removes the separation step. That measurement takes a minute, and it decides which row on the table actually matters.
