HSM SECURIO P44i 1/32 x 3/16 Cross Cut Department Document Shredder - HSM1874

P-7 is the strictest paper class DIN 66399 defines, and this is HSM's large-chassis machine for it. Paper is reduced to 1 x 5 mm particles, 5 mm2 each, at the limit of what the standard allows, through a 400 mm throat into a 205 litre container. Everything about the machine is a consequence of that cut. HSM lists paper and nothing else as an accepted material, capacity falls to 11 sheets, and the lifetime cutting-roller warranty that covers the P-2 to P-5 models does not extend here. What you get in exchange is destruction that nobody is going to question.

Key Features

• 1 x 5 mm particle cut, DIN 66399 P-7. 5 mm2 particles with a 1 mm width. P-7 is the strictest paper class the standard defines; nothing above it exists.
• Large-format high-security chassis. 400 mm throat and 205 litre bin. Most P-7 machines are small-office units; this one is sized for sustained work.
• 11 sheets per pass at 80 g/m2. Two more than the P40i equivalent, which over a long purge is a meaningful difference.
• 1900 W IntelligentDrive. Three operating modes and automatic start and stop, driving a cutting unit that does an extraordinary amount of work per sheet.
• Automatic paper-jam prevention. The control system recognises an over-thick stack quickly. On an 11-sheet machine that is a feature you will use.
• Integrated automatic oiler. A 1 x 5 mm cutting unit will not tolerate poor lubrication. The machine oils itself and you refill it with HSM cutting block special oil.
• EcoSmart standby at 0.1 W. A machine sized for a floor can be left switched on without a standing energy cost.

Specifications

Sheet capacities are HSM's per-model figures at 80 g/m2 A4. HSM's range brochure quotes capacity at 70 g/m2, which reads roughly 15 percent higher, so figures quoted elsewhere may not match.

What's in the Box

Supplied as a floor-standing machine with the 205 litre container and factory-fitted automatic oiler. Collection bags and cardboard disposal boxes are not included: HSM lists a reusable collecting bag and a P44i cardboard box for this container, plus cutting block special oil. At 105 kg, confirm access and final position before delivery.

Who Should Buy This - and Who Should Not

Buy it if you have a written P-7 requirement and enough volume that the P40i 1 x 5 mm at nine sheets would be a bottleneck. The extra throat width and the 205 litre bin make long high-security purges practical.

Do not buy it if you need NSA-listed equipment. The P44i does not appear on the NSA/CSS Evaluated Products List for paper shredders dated July 2025; the HSM entry in this family is the SECURIO P40i L6 (1 x 5 mm) OMDD Combi. A 1 x 5 mm particle matches the NSA/CSS 02-01 dimension, but dimension is not approval. Do not buy it either if you also need optical media destroyed, because HSM lists paper only for this article: the version with the separate 2 x 2 mm OMDD unit adds O-6 and T-6 media classes. And if your real requirement is commercial confidentiality, the P44i 1.9 x 15 mm at P-5 does 25 to 27 sheets and keeps the lifetime cutting-roller warranty.
