Operators dealing with surface treatment face the problem of fine dust every day: while working, a large amount of very fine dust is produced that makes the work of operators dangerous, even when they have personal protective equipment.

Using an industrial vacuum cleaner together with working machines (such as smoothers or scarifiers) is the ideal solution to this problem, but how do you choose a vacuum cleaner? The company Marwind makes some recommendations in this regard.

3 are the characteristics that should be considered:
1. Size and ease of transport: the vacuum cleaner must have contained dimensions in order to be transported in small media (such as minivans);
2. Filter filtration and cleaning systems: the efficiency and cleaning system of the filter are essential given the volatility of the dust;
3. Safe handling and disposal of aspirated material.

To meet these needs, the Italian manufacturer Delfin has developed specific suction solutions for the surface treatment sector thanks to the collaboration with the end users of the product. The range comprises:

- Compact vacuum cleaners easily transportable;
- Vacuum cleaners with high filtration effectiveness (up to 0.18 microns for HEPA filters) and automatic filter cleaning systems;
- Vacuum cleaners and separators equipped with Longopac safe collection systems, which allow a quick and safe removal of the aspirated dust.
