Frequently Asked Questions
What makes this different from the 41434 apart from size?
Three things: a 12-inch feed opening instead of 10.25, a 38-gallon bin instead of 30, and a department cabinet at 146 pounds against 102. The cut, the P-7 rating and the NSA high-volume rating are identical. Sheet capacity is the same 8 per pass. You are buying width, bin capacity and a shared-use cabinet, not a faster cut.
Is it NSA approved, and how do I confirm that?
Yes. The 41534 is listed on the current NSA/CSS Evaluated Products List for paper shredders with a high-volume rating. NSA/CSS 02-01 requires both a maximum 1 mm x 5 mm particle and EPL listing of the specific model - a P-7 rating on its own is not NSA approval. The EPL is republished quarterly; if approval is contractual, cite the edition in force at your purchase date.
Will 11 x 17 tabloid fit?
Yes, the 12-inch throat takes tabloid flat. That is the practical reason to choose this over the 41434, whose 10.25-inch opening requires folding wide sheets - and folding doubles the effective thickness, which on a machine rated for 8 sheets is a real limitation.
Does it shred anything other than paper?
Dahle publishes no optical-media or credit-card rating for the CleanTEC high-security line and lists paper as the media. Remove staples, clips and fasteners before feeding. Classified optical, magnetic and solid-state media destruction is covered by separate NSA/CSS specifications and requires separately evaluated equipment.
How much space does it need?
The cabinet is 21 x 29 inches on the floor and 34.5 inches tall, on lockable casters. Allow clear space in front for the bin to be withdrawn and enough room to present a full 12-inch-wide sheet to the throat. At 146 pounds it rolls easily on hard floor but needs two people to unpack and to cross a threshold.
What are the ongoing consumables?
Three: Dahle shred bags #20726 for the 31-55 gallon bin range, Dahle shredder oil for the EvenFlow Lubricator, and replacement CleanTEC dust filters. None are supplied in quantity with the machine. Budget for all three - a high-security machine that runs out of oil or is used with a clogged filter will not perform as specified.
Can it run continuously through a large purge?
Dahle specifies a chain-driven, continuous-duty motor, so it is built for sustained running rather than short bursts. The practical limit on a large purge is the 8-sheet pass rate rather than the motor. Dahle does not publish a run-time and cool-down figure for this model; the motor is thermally protected and will stop itself if it overheats.
