More shredding, less stopping. A promax shredder uses enhanced fan cooling technology which keeps the shredder cooler for longer so it can operate for extended periods without overheating. The promax RPX612 shreds 6 sheets at a time into secure P4 (4 x 40 mm) cross cut pieces. It can handle staples and credit cards and features a compact 12 Litre bin. Simple to operate with a long run time. Ideal for small and medium business environments. Every shredder runs for a limited period of time before it needs to cool down. The longer you need to shred, the more run-time you will need.
