301 DRY The professional industrial vacuum cleaner

The Mistral 301 Dustop industrial vacuum cleaner is one-of-a-kind in its sector. A compact industrial vacuum cleaner that successfully combines the robustness, power and filtration efficiency of a real industrial vacuum cleaner, with the handling, convenience and user-friendliness of a typical commercial vacuum cleaner.


The 301 DUSTOP vacuum cleaner comes with a powerful single-phase Lamb-Ametek motor and extremely solid steel chassis (also available in stainless steel). Inside the steel filter chamber there is a conical filter with large filtration surface and high filtration efficiency (1 micron, class M). The new semi-automatic cleaning system of the Dustop filter means the operator can easily clean it simply by raising a flap on the chamber a few times. This simple action guarantees there is always maximum filtration capacity and that the vacuum cleaner is performing at its best.


Thanks to its modular structure, the vacuum cleaner can also be fitted with a high efficiency filter bag, a Class H absolute filter (HEPA) or one of a variety of special filters, purpose-built for specific applications.
