Cleaning after repair requires the use of special equipment. The fact is that collecting construction dust with a conventional vacuum cleaner is not recommended for reasons of harmful effects on the design of the device, and from the point of view of environmental safety. And this is not to mention the waste of building materials that are physically not amenable to household appliances. Accordingly, the question arises of how to choose an industrial vacuum cleaner without a bag for collecting dust? Such equipment has many similar operational parameters with conventional models, but there are specific selection criteria that are characteristic only for building modifications.
Key selection criteria
A key indicator of the performance of any vacuum cleaner is its power, which affects productivity. In the initial segment, the power potential usually does not exceed 1.5 kW. But if productive equipment is required, then we select an industrial vacuum cleaner with a capacity of 5-7 kW. This is enough for putting in order a small room after finishing work, and for regular maintenance of a professional workshop. It is also worth noting the rate of absorption of air mass per second. In powerful models, this value varies from 50 to 70 l / s.
The next selection criterion is roominess. Since in this case the unit is considered without a traditional dust collector, the volume in the water tank should be estimated. On average, industrial vacuum cleaners without a dust bag can hold 100-150 liters in a tank. Accordingly, the higher this indicator, the less often the reservoir will be updated. But, on the other hand, as the capacity increases, the dimensions of the equipment also grow.
Proper selection
Understanding the consumer’s love for simple, universal solutions, manufacturers strive to widely represent multifunctional devices in their lines. But as practice shows, specialized models more often have the greatest efficiency and a good work resource. On the market you can find industrial vacuum cleaners without a bag to collect dust, sawdust, glass fragments, metal chips, etc. You can say this is a basic range of tasks, but more complex operations may be required.
For example, collecting dirty water, working with polymer mortar, cleaning the room from gypsum with cement or crushed stone. If you use a universal building machine from the range of budget offers for such tasks, then it will last for a short time. Conversely, it makes no sense to use high-power industrial vacuum cleaners without a bag to collect dust or perform other simple procedures that a model from the average power range can handle.
Additional functionality - what to consider?
Since this is a utilitarian technique for solving very specific practical problems, most of the additions provide real assistance to the operator. First of all, it is recommended to provide for the possibility of automatic cleaning of filter elements. Using his own air stream, the vacuum cleaner literally blows through the membrane, saving it from litter and dust. As for the tank, it will not be out of place to provide for the indication of filling - this is a simple but useful addition to the work. So that the selected industrial vacuum cleaner without a dust bag does not waste unnecessary energy, it is worthwhile to initially turn to models with the ability to adjust performance indicators by mode. Such a function just makes the equipment universal. For example, in working with broken brick and stone, the user will be able to turn on the most productive mode, and litter in the form of wood chips should be cleaned at minimum speed.
How to evaluate the reliability of the unit?
Even information with the characteristics of the materials used in the construction does not always provide objective data regarding the durability and reliability of the equipment. Nevertheless, to minimize the risk of premature breakdowns, new technological additions in the filling of vacuum cleaners allow. For example, an air purification and cooling system for turbines immediately has two beneficial effects - it extends the working life of the element base and ensures the stability of the function in conditions of excessive dust. With these additions, bagless industrial vacuum cleaners are often used after dusting old plaster. If we return to the materials of manufacture, then the choice is simple - the metal case is stronger, and the plastic one is lighter and more convenient.
Manufacturers
The leader is rightfully considered the manufacturer Karcher, who has significantly raised the level of technological performance of professional cleaning equipment, as well as improved the ergonomic advantages of his products. True, there is an industrial vacuum cleaner without a bag for collecting dust from Karcher about 20-30 thousand rubles. For those who do not want to pay too much, but count on a decent level of quality, it is also worth taking a look at vacuum cleaners from Makita, Hitachi and another German company Stihl. Already in the mid-range lines of these brands, you can find models endowed with a fairly high power and volumetric tank.
Conclusion
In the selection process, one should not ignore the comfort of operation. Modern models have made a huge breakthrough in terms of combining safety and convenience. But, the best industrial bagless vacuum cleaner, of course, has a whole range of positive qualities. It should be a productive, reliable, functional and at the same time energy-efficient model. Not every vacuum cleaner has such a combination of characteristics, but in most cases such a wide range of advantages is not required. Therefore, the optimal model of cleaning equipment is one that is suitable for specific needs. After all, far from always need high power and a spacious tank. The only requirements that can be considered universal are durability, ergonomics, quality of cleaning and economy in energy consumption.
