Frequently Asked Questions
Is P-4 enough for personal data?
For most personal data, yes. DIN 66399 P-4 is the level generally treated as the minimum for documents that identify an individual, and it is what most privacy programmes specify by default. For special categories — health records, payroll, anything a regulator would call sensitive — many organisations step up to P-5. The B26 exists at 1.9 x 15 mm for exactly that, at a cost of roughly a third of the throughput.
Can this shred staples and paper clips?
Yes. HSM lists staples and paper clips as accepted materials, so stapled reports can go in as they are. Remove binder clips, ring-binder mechanisms, spiral bindings and plastic covers. Regular fastener use is normal for this cutting head and the induction-hardened cylinders carry HSM’s lifetime warranty at P-4, but the machine still benefits from being oiled on schedule.
Can it shred CDs and DVDs?
Yes, and this is one of the few B26 cutting heads that can. HSM rates it O-3 for optical media and lists CDs and DVDs as accepted. Feed discs one at a time rather than mixed with paper. Note that the P-5 and higher B26 variants do not accept discs at all, so if optical media is part of your disposal stream this version is the practical choice.
How often will the bin need emptying?
HSM rates the 55-litre bin at roughly 672 sheets of 80 g/m² paper at this cut size — call it a ream and a third. A typical department empties it once a week. Running continuous clear-outs at the full 14-16 sheets per pass, you will reach the top in about forty-five passes.
Is this NSA approved?
No. NSA/CSS 02-01 requires a 1 mm x 5 mm maximum particle and a listing on the NSA Evaluated Products List. A 4.5 x 30 mm cross cut is far coarser and this model is not listed. P-4 is a commercial standard and a sound one; it is not an NSA standard, and any seller describing a P-4 machine as NSA approved is wrong.
How many people can share it before it bottlenecks?
The 610 W motor is rated for continuous operation, so the real constraints are the feed rate and the bin. A department of eight to ten doing routine daily shredding will be comfortable. If several people regularly arrive with full archive boxes, look at the B32 for the larger container or at an autofeed model so nobody stands at the machine.
