MÜHLEN Ofen 330C
Cross-Cut Paper Shredder
High German Engineering
The MÜHLEN Ofen 330C features a cutting/shredding blade made of specially hardened steel, backed by a 5-year warranty. With a 16-sheet-per-pass cutting capacity, the blade system has a strong gear and mechanical structure.
Its powerful motor can shred documents non-stop for over 12 minutes.
Smart Capacitive Motor
The powerful capacitive motor system automatically shreds documents and stops automatically when finished, while also automatically cooling an overheated motor, halting shredding, and alerting the user with an LED light.
Automatic & Low Noise
The MÜHLEN Ofen 330C operates almost silently with a noise level below 55 decibels. The entire system is fully automatic, with maximum attention paid to user safety to reduce the risk of injury to zero.
4x20mm Cross-Cut Confetti Shredding
The MÜHLEN Ofen 330C shreds documents into micro cross-cut particles measuring 4mm x 20mm, meeting DIN P4 security level. This makes it impossible to reassemble or read the destroyed documents.
Multiple Feed Openings
With three separate feed openings for paper shredding, CD/DVD shredding, and credit card shredding, the machine processes every type of workload with its own dedicated mechanism for maximum efficiency. It is mounted on 4 wheels, two of which have brakes, for easy movement around the office.

Smart Control Panel
The control panel, featuring ON(Auto)/OFF and Forward/Reverse buttons, alerts the user to various conditions via an LED indicator system. These include power status, waste bin not inserted, waste bin full, motor overheating, and paper jam warnings.
2m/Minute Cutting Speed
With micro cross-cut shredding, it can destroy more than 100 sheets per minute (2 meters per minute). The MÜHLEN Ofen 330C features a 30-liter, removable waste bin with a viewing window, and stops automatically to alert the user when the bin is full.

MÜHLEN Ofen 330C — Cross-Cut Paper Shredder with 16-Sheet Capacity
Who Is It For?
The MÜHLEN Ofen 330C is a cross-cut paper shredder for medium to busy offices with a steady stream of confidential documents. Its 4x20 mm confetti cut at DIN P4 fits accounting, legal, HR, healthcare and public-sector departments where personal data must be protected. Because CDs/DVDs and credit cards go through their own openings, units producing mixed waste can manage with a single device. At 12.3 kg net on 4 wheels, it works well as a shared machine moved between departments.

Frequently Asked Questions
What size are the shredded pieces?
Paper is cut to 4×20mm and credit cards to 4×30mm, which corresponds to DIN P4.

Non-stop operation lasts more than 12 minutes. If the motor overheats, it stops automatically and the LED warns you.
What warranty does the 330C have?

Usage and Care Tips
Send each material to its correct opening: paper to the document slot, discs and cards to their own slots. As you approach 12 minutes of continuous use, allow a short pause so overheat protection does not need to step in. Check the 30-liter bin through its window and empty it in good time. Clear jams with the Forward/Reverse buttons, take out paper clips where possible, and lock the wheel brakes while the 330C stands in its working position.
