Industrial vacuum cleaners are designed for cleaning construction debris, as well as for cleaning industrial premises from specific debris, such as wood or metal shavings, concrete dust and other contaminants. Industrial often referred to as construction, work on the principle of household models. They differ from the latter in high engine power, which means their ability to absorb heavier wastes (such as broken pieces of cement).
The advantages of industrial models include high performance and the availability of specialized filters that can sift not only large debris, but also fine dust of various origins.
There are shortcomings: all of them relate to the design features or the specifics of the filter element arrangement - some branded manufacturers, trying to attract more buyers, took the path of minimizing structural and other shortcomings, using feedback from customers and best practices in the development of industrial devices to improve.
Popular brands: Flex, Mirka, Hanko, Rupes are well-known companies with a rich history. p>
Technical features of construction vacuum cleaners
The discharged state of the air inside the device, or in other words, the reduced pressure due to which objects are pulled inward, is created by an electric motor, on the output shaft of which a turbine is located. The latter creates a vacuum due to the presence of an impeller with backward curved blades (when ventilated, they are curved forward). To increase the power of models connected to a single-phase (household) power supply network, up to 3 turbines are installed, coupled with three single-phase electric motors. If you work in a workshop equipped with a three-phase supply network, from which you can obtain the required power without the use of additional tricks, one turbine is installed, the impeller of which is interfaced with a three-phase electric motor. The case of an industrial vacuum cleaner can be made of steel or high-strength plastic, resistant to mechanical stress and the negative impact of aggressive environments. All industrial vacuum cleaners are equipped with a filter element that works on the principle of an automobile filter.
Additionally, technical solutions such as:
- a swirl chamber with a rotating foam layer, effective when it is necessary to clean from gases;
- a chamber for hitting an air stream against a water barrier;
- centrifugal precipitator.
Vacuum cleaner manufacturers are paying more and more attention to plastic for the production of body parts, as a modern and lighter material, which ultimately significantly reduces the final weight of the device.
