The dry suction method is very often used to clean rooms and equipment where it is not possible to clean with liquid means for a variety of reasons.

The suction in dusty operations (bakeries, sharpening and welding services ...) of powder fine loess of flour, metal sawdust or scalings is performed by industrial vacuum cleaners in versions according to the dust class.
We use professional machines of class L - low risk for common dust in construction as well as professional machines of class M - medium risk, used mainly for hazardous dust created in dusty operations. We only use class M filters to exhaust operation dust in safety zones 21 and 22.

All machines used, including attachment, have an antistatic treatment for explosive environments.
