Frequently Asked Questions
Does the cross-cut Pure 320 shred CDs?
No, and this catches people out because the strip-cut version of the same machine does. The cross-cut Pure 320 is rated E-3, F-1, P-4 and T-4 under DIN 66399, with no O class for optical data carriers. Feeding a disc into it risks damaging a cutting head built for paper. The smallest Pure model that combines P-4 paper security with an optical rating is the Pure 420 cross-cut, which carries O-3.
Is the cut really 1/8 x 1 1/8 inch?
Not exactly. HSM specifies 3.9 x 30 mm for article 2333121, which converts to about 0.154 x 1.18 inch - nearer 5/32 x 1 3/16 than 1/8 x 1 1/8. The rounded imperial figure has been repeated widely, including in our own listing title. What matters for compliance is the particle area: 117 mm2, inside the 160 mm2 that DIN 66399 allows for P-4.
How often will the bin need emptying?
Less often than the sheet capacity suggests. HSM rates the 25 litre container at roughly 350 shredded sheets on this model, because particle cut compacts far better than strip cut. For an office destroying fifty pages a day that is about a week between empties. The container pulls out of the cabinet as a drawer rather than needing the top lifted off.
Can it handle staples, clips and stapled reports?
Staples and paper clips are within HSM's specification for the steel cutting rollers, so ordinary stapled documents can go straight in. What you should not do is feed a thick stapled report as a block - eight to nine sheets is the pass limit and a twenty-page report needs splitting. Bulldog clips, ring binders, plastic wallets and laminated pages should always be removed.
Is it quiet enough to sit in an open-plan office?
At approximately 55 dB(A) idle it is one of the quieter machines in its class, and quieter than the desktop Pure 120 and 220 despite the larger motor. Under load it is noticeably louder, as all shredders are. In practice it is unobtrusive in a room where people are working, and it will be noticed in a room where people are on video calls.
Is P-4 enough, or should I be looking at P-5?
P-4 is the level most organisations specify for records containing personal data, and it is what a typical destruction policy or auditor expects for HR, payroll, patient administration and customer files. P-5 exists for material where the consequence of reconstruction is serious - commercially sensitive research, legal privilege, classified work. If your policy names P-5, this machine does not meet it and no Pure 320 variant does.
