Frequently Asked Questions
Dahle rates the paper cut P-3 - does 5 x 70 mm really qualify?
This is worth flagging honestly. DIN 66399 caps a P-3 particle at 320 mm2. A 5 x 70 mm particle is 350 mm2, which is marginally outside that limit and inside the 800 mm2 ceiling for P-2. Dahle publishes P-3 for this machine in both its brochure and its own product page, and we have reproduced the manufacturer's rating here. If your policy requires strict, audited DIN P-3 conformance, ask Dahle for the test documentation before you order rather than relying on the catalogue figure.
Is it NSA approved for hard drive destruction?
We found no NSA/CSS Evaluated Products List entry for the 828 HD and will not claim one. Among the Dahle machines in this range, the 818 HD appears on the NSA list of hard disk drive deformers, and the 707 PS, 727 CS and 747 CS appear on the paper shredder EPL. If an EPL listing is mandatory for your programme, the 828 HD is not currently the machine to specify for drives.
What electrical supply does it need?
220 V three-phase. That is a formal electrical installation, not an extension lead, and it needs to be in place before delivery. Dahle does not publish the circuit amperage for this model, so have your electrician confirm the requirement with the dealer at the quotation stage rather than on installation day. The 700-series machines by contrast all run on 115 V.
Can it take a whole folder including staples and clips?
Dahle lists paper, hard drives and optical media as accepted materials for the 828 HD. It is a P-3 machine with a 4.5 HP motor and a 100-sheet capacity, which is a far more tolerant cutting head than the P-7 machines in the 700 series - but Dahle does not specifically list staples and paper clips for this model the way it does for the 909 HS and 919 IS. Remove heavy binder clips and metal fasteners as a matter of routine.
How often do the bins fill?
The paper bin holds 31 gallons and the media bin 26 gallons, and at 100 sheets per pass the paper bin is the one you will be emptying. A sustained records clearance will fill it within a couple of hours of continuous feeding. Both are roll-out bins, which is the only sensible arrangement at this weight - lifting a full 31-gallon bin of shredded paper out of a cabinet is a manual handling problem.
How much floor space and floor strength does it need?
The cabinet is 38.25 x 33.5 x 46.5 inches, and you need clearance in front of both feeds plus room to roll two bins out. The weight is 1,257 lb concentrated on casters, so check the floor loading if it is going anywhere other than a ground-floor slab. Delivery requires a dock or a liftgate.
Is 60 dB quiet enough for an open office?
60 dB is around normal conversation level, so it is not objectionable in itself. The bigger problem with putting the 828 HD in an office is everything else about it: three-phase power, 1,257 lb, and a footprint that needs clearance on two sides. This machine belongs in a dedicated destruction room or a warehouse area, and the noise rating is the least of the siting constraints.
