HSM Securio B-Series Compared: B22, B24, B32, B34 and B35
The HSM Securio B-series is the brand's core office range, and the model number tells you the size class: B22 and B24 are desk-side and small-office machines, B32 and B34 are shared office and small department machines, and B35 sits at the top of the line for departmental use. Within each size class, the suffix after the model number gives the cut and therefore the security level, which is why a B34 can appear as anything from a strip-cut P-2 to a micro-cut P-5. Pick the size class by user count and volume, then pick the cut by what is written on the paper.
Our Securio model guide covers the whole line. This page is about the B-series specifically.
How to read a Securio B model number
Two independent choices are encoded into it:
- The number indicates the frame and throat size class, which drives sheet capacity, bin volume and footprint.
- The cut designation that follows indicates particle size and therefore the DIN 66399 security level, from strip cut through cross cut to micro cut.
These are independent. Choosing a bigger number does not make the machine more secure, and choosing a finer cut does not make it handle more paper. In fact it does the opposite — within one frame size, the finer the cut, the lower the sheet capacity.
Choosing the size class
| Model class | Typical setting | Users |
|---|---|---|
| B22 / B24 | Desk-side, private office, small practice | 1–4 |
| B32 / B34 | Shared office machine, small department | 5–20 |
| B35 | Department machine, higher volume | 20+ |
The step from B24 to B32 is the meaningful one for most buyers. It is where the machine stops being something one person uses and becomes something a floor shares, with the bin capacity and duty cycle to match.
Choosing the cut
This is a data question, not a volume question.
- Strip cut (P-2) — internal, non-sensitive paper only. Rarely the right answer today.
- Cross cut (P-4) — the commercial default. HR files, invoices, contracts, correspondence. See cross-cut machines.
- Micro cut (P-5) — regulated personal data: medical, financial, legal. See micro-cut machines.
Our P-4 vs P-5 guide works through the choice without overbuying, and the DIN 66399 explainer covers the standard itself.
What you gain going up the range
- Sheet capacity per pass, so fewer passes and less queueing.
- Bin volume, so emptying moves from twice a week to weekly.
- Throat width, which is what lets people feed legal paper and folded documents without preparing them first.
- Duty cycle headroom, which is the difference between a machine that runs all afternoon and one that trips its thermal cut-out.
What stays the same
Build approach is consistent across the B-series: solid hardened steel cutting shafts, a metal gear drive, and serviceable parts rather than a sealed assembly. That is the reason the range holds up in shared use — see why German-engineered shredders cost more.
Frequently asked questions
What does the number in an HSM Securio B model mean?
It identifies the frame and throat size class, which determines sheet capacity, bin volume and footprint. It does not indicate the security level — that comes from the cut designation that follows.
What is the difference between the B24 and the B34?
They are different size classes. The B24 is a desk-side and small-office machine for roughly one to four users. The B34 is a shared office machine with greater sheet capacity, a larger bin and more duty-cycle headroom, suited to around five to twenty users.
Which Securio B model do I need for HIPAA?
Choose the size class by user count and volume, then specify a micro-cut P-5 version of it. HIPAA does not name a DIN level, but P-5 micro-cut is what US compliance officers generally expect for medical records.
Does a higher B number mean a more secure shredder?
No. Size class and security level are independent. A larger B model with a cross cut is less secure than a smaller one with a micro cut. Specify both separately.
Why does the same model have different sheet capacities?
Because the cut changes the work per sheet. Within one frame size, a micro-cut version will take noticeably fewer sheets per pass than the cross-cut version, since the cutting head makes many more cuts per sheet.
