Suction unit

During the milling and grinding process, very fine dust is formed which spreads into the air. Due to the small distance between the worker and the sanding position these dusts are inhaled in high concentrations even when sanding is considered to be minimal. These particles penetrate easily and deeply into the lungs, at the risk of creating permanent asthmatic pathologies and serious lung diseases. Highly damaging effects on the skin and respiratory system have also been found in the case of dental plaster, coating masses and mixed dusts, which fall within the general dust limit.
In the absence of a dental aspirator in the laboratory, the legal limit values are clearly exceeded for most powders. By optimising the suction systems and using a modern vacuum cleaner, it is possible to reduce the weight load.

The most advanced technologies are able to obtain the double result of optimizing both the quality of work and the welfare of the technician.

There are different models of aspiration systems on the market, a very good solution is the Zubler aspiration systems for single or multiple workstations, or the centralized systems.

Aspiration systems with outward air discharge are particularly effective and improve air throughout the laboratory. Choosing a centralized system improves the indoor climate by conveying exhaust air outside; in the working environment, no toxic and unpleasant vapours remain during the processing of plastic materials or residual micro-dusts. In addition, without a aspirating motor in the working environment the noise is reduced, there is more space for the instruments and more freedom of movement, consequently a greater cleanliness of the laboratory thanks to the sockets installed for the dusts. Finally, costs are reduced because energy consumption is lower thanks to the large and highly efficient compressor motors.

It is always possible to install a central aspiration system in a new laboratory, or to carry out a subsequent installation after expansion or renovation. The centralized aspiration technique guarantees a professional and clean execution for every single installation.

An aspiration system must have a powerful air exchange and needs a lot of space for the filtering surface. Large power compressors are large or have to produce a high speed; the smaller they are, the more noise they generate. A good soundproofing requires surfaces and volumes: providing a reasonably adequate space for the suction system, you will surely find a suitable solution.
Alternatively exist the portable suction boxes, that is small or medium size aspirators in which the dental material is processed and that aspirate the residues of the processing.
