A medium office shredder is a cross-cut or micro-cut document destruction machine built for teams of 3 to 10 users who shred moderate to high volumes of paper daily in a shared office environment. The New United M3150C is the medium office model in the New United range stocked by DigiShred, delivering DIN P-4 cross-cut shredding at 20 sheets per pass with a 51.5-litre bin suited to full-day commercial use. DigiShred supplies this model to South African businesses that need a reliable, continuous duty machine for everyday confidential document disposal without the cost of a high security upgrade.
Key facts:
| If you need… | Choose | Why |
| Standard daily shredding for a small team | New United M3150C | 20 sheets, P-4 cross-cut, 51.5L bin |
| Higher sheet throughput at P-4 | Kobra Medium Office range | Multiple models up to 25 sheets per pass |
| P-5 micro-cut security at medium volume | New United M3150M (High Security) | Same bin, fewer sheets, finer particles |

The New United M3150C suits teams of 3 to 10 users who shred confidential business documents daily and need a machine that runs continuously without overheating or requiring cool-down breaks. Its 20-sheet capacity and 51.5-litre bin make it a practical fit for offices that produce moderate to high daily shredding volumes across a shared workspace.
DIN P-4 cross-cut security satisfies POPIA requirements for the disposal of most personal information held by South African businesses, covering standard records, client correspondence, and employee documents.
Offices and departments that typically use the M3150C:
The M3150C handles moderate to high daily shredding volumes at 20 sheets per pass with a 51.5-litre bin, making it well suited to teams where one or two people shred regularly throughout the day or multiple team members bring batches to a shared machine.
As a DIN P-4 machine it processes more sheets per pass than a P-5 model of comparable size, which is the standard advantage at this security level.
Use this guide to match your volume to the right choice:
| Daily Volume | Team Size | Recommended Choice |
| Up to 100 sheets | 1 to 2 users | New United Home/Office range |
| 100 to 400 sheets | 3 to 8 users | New United M3150C (medium office) |
| 400+ sheets at P-4 | 8 to 15 users | Kobra Medium Office or Kobra Large Office range |
| 100 to 400 sheets requiring P-5 | 3 to 8 users | New United M3150M (high security) |
The New United M3150C is a cross-cut shredder built for continuous commercial use, with a 310mm entry width that accommodates A4 documents in both portrait and landscape orientation and a 51.5-litre bin that reduces how often the bin needs emptying during a working day.
At DIN P-4, it produces 3.9x40mm cross-cut particles that satisfy POPIA requirements for confidential document disposal across most standard business record types.
Key features of the M3150C:
The M3150C and M3150M share the same 51.5-litre bin and 310mm entry width but differ in security level and sheet capacity, which makes the choice straightforward once you know what your documents require.
The M3150C suits offices where DIN P-4 cross-cut is sufficient; the M3150M suits offices where DIN P-5 micro-cut is required for stricter confidentiality or higher-risk personal information.
| Feature | New United M3150C | New United M3150M |
| Security level | DIN P-4 cross-cut | DIN P-5 micro-cut |
| Shred size | 3.9x40mm | 2x8mm |
| Sheet capacity (80g/m2) | 20 | 15 |
| Bin volume | 51.5 L | 51.5 L |
| Entry width | 310mm | 310mm |
| Best for | Standard business records, POPIA P-4 compliance | Personal information, financial records, legally privileged documents |

A New United medium office shredder is a DIN P-4 cross-cut document destruction machine designed for teams of 3 to 10 users shredding moderate to high volumes of confidential business documents daily. The M3150C, the medium office model in the New United range available from DigiShred, handles 20 sheets per pass and shreds paper, CDs, DVDs, credit cards, staples, and paper clips into 3.9x40mm cross-cut particles.
POPIA requires that personal information be destroyed in a manner that prevents reconstruction, and DIN P-4 cross-cut satisfies this requirement for the vast majority of standard business records held by South African organisations. Offices handling higher-risk personal information such as medical records, financial account data, or legally privileged documents should consider stepping up to the DIN P-5 New United M3150M.
Both models share the same 51.5-litre bin and 310mm entry width, but the M3150C operates at DIN P-4 cross-cut (3.9x40mm) with a 20-sheet capacity, while the M3150M operates at DIN P-5 micro-cut (2x8mm) with a 15-sheet capacity. The M3150C is the right choice for standard confidential business records; the M3150M is the right choice where stricter document security is required.
Start by estimating your team size and daily shredding volume, then determine the security level your document types require under POPIA. If your team has 3 to 10 users shredding moderate volumes of standard business records at DIN P-4, the M3150C is the fit; if your records contain sensitive personal information requiring DIN P-5, choose the M3150M instead.
