Frequently Asked Questions
Is P-4 enough for personal data and confidential records?
For most organisations, yes. DIN 66399 P-4 caps particle area at 160 mm2 and the 50314 produces about 127 mm2, so it sits comfortably inside the class. P-4 is the level normally specified for confidential business records and personal data, and it is what most client confidentiality clauses expect. If your own policy, a regulator or a contract names P-5 or above, this machine does not meet it - check before you buy rather than after.
Do I ever need to oil it?
No, and you should not. The 50314 is an oil-free design; Dahle states it maintains peak performance without lubrication maintenance. Adding shredder oil, or running oiled lubricant sheets through it, is not part of the intended maintenance and in the case of sheets can leave paper residue in the cutting head. Emptying the bin before it overflows is essentially the whole maintenance routine.
Can it shred CDs, DVDs and credit cards?
Yes. Dahle rates the 50314 for CDs and DVDs, credit cards, staples and paper clips in addition to paper, so you do not need a second device for media destruction. Feed discs and cards individually rather than stacked. Note that this is a DIN O-3 rating for optical media, which is appropriate for routine disposal but not for classified media - that requires an NSA-listed optical destroyer.
How does it compare with the 50310?
Same cabinet, same 23-gallon bin, same 10.25-inch throat, same 46 dB, both oil-free, both rated for CDs and cards. The 50310 is P-3 with a roughly 189 mm2 particle and takes 20 sheets a pass at 95 lb. The 50314 is P-4 at about 127 mm2 and takes 16 sheets at 89 lb. You give up four sheets per pass and gain a materially smaller particle. For most buyers the 50314 is the right side of that trade.
Will legal-size or tabloid paper go through?
Not unfolded. The throat is 10.25 inches, which suits letter paper fed long-edge first. Legal (8.5 x 14) and tabloid (11 x 17) sheets need folding, and a folded sheet counts as two against the 16-sheet capacity. If legal paper is a regular part of your workload, Dahle's 12-inch and 16-inch throat cabinets are the better specification.
What bags does it take, and are they included?
It takes Dahle 20725 shred bags, rated for 20-30 gallon shredders and sold 100 to a box. None are supplied with the shredder. They are 1.5 mil gusseted plastic bags that open out to fill the cabinet. A generic bin liner of similar size will fit but is more likely to split when a full bag of cross-cut waste is lifted out.
Is this shredder NSA approved?
No. The 50314 is a P-4 cross-cut office machine and does not appear on the NSA/CSS Evaluated Products List. NSA/CSS 02-01 requires a maximum particle of 1 mm x 5 mm plus the specific model being listed, and a P-4 cut is far outside that. If you need NSA-listed destruction, Dahle's EPL-listed models are the 40334, 40434, 20394 and the portable 20434DS.
