Vacuum Cleaner Price and Types

There are various types of professional vacuum cleaners, from the classic wet and dry vacuum cleaner to the more sophisticated industrial vacuum cleaners for extreme uses. Basically the main factors that determine the choice of professional vacuum cleaner are the type of material that will be vacuumed and even more the severity of the service. In practice, if I am a private individual who has to occasionally vacuum the pellet stove, car interiors or garage, I will opt for a domestic or semi-professional vacuum cleaner; while if I am a craftsman who works with plasterboard, or a carpenter with wood, I will opt for a professional vacuum cleaner for prolonged / heavy use and perhaps with some options that make my work more pleasant; finally, for special applications such as the suction of fine or toxic dusts, I will have to purchase a vacuum cleaner for fine dust or an industrial vacuum cleaner. Below are the main types of professional vacuum cleaners.

What characterizes a Vacuum Cleaner

The main feature to be taken into consideration when evaluating the quality of an aspirator is the suction efficiency which is given by the combination of various factors such as air flow, motor power and depression.

• The air flow is the volume of air sucked in (expressed in liters per second and calculated as the product of the average air speed and the diameter of the duct).
• depression measures the suction force (the ability of the vacuum cleaner to lift dirt) and is normally expressed in mbar. This value is inversely proportional to the flow rate and therefore, the smaller the diameter of the suction pipe is, the lower the flow rate and the greater the speed of the air and the force with which the dirt will be detached from the surface.
• the power of the motor , expressed in Watts, says nothing about the efficiency of the suction and is not directly proportional to the ability of the extractor to perform its task: if the extractor has not been designed and built in an effective way, the power supplied will simply be dispersed in the form of heat without increasing the suction capacity of the machine.

It is therefore necessary to find a parameter that uniquely expresses the real power of the aspirator and this has been identified as the ratio between the Suction Power (PA = "Volume of air sucked in per second" x "Depression") and the Power of the Vacuum motor (PM):

Aspirator efficiency = PA / PM

and this value in professional products is practically double compared to those expressed by machines for household use!

Shell materials and construction

Professional vacuum cleaners always adopt the "bin" construction. But which material is preferable to choose for the shell?

Generally, it is possible to choose between plastic and stainless steel .

• The polypropylene drum is flexible, resistant and offers excellent resistance to aggressive chemicals and is therefore advisable if the vacuum cleaner must be often transported or used for the collection of chemical products.
• The stainless steel barrel, on the other hand, resists scratches better and offers higher stiffness and stability characteristics than the polypropylene one. It is also more valid from an aesthetic point of view if the machine is to be used in environments with public presence.

The frame in turn can be fixed or tilting. In general, the tilting drum is more convenient for unloading powders and solids. The fixed drum, on the other hand, is more suitable for handling liquids (it is generally equipped with a drain pipe) and therefore avoids the lifting effort.

Number of engines

Industrial vacuums can be designed with up to 3 motors that can be switched on independently to increase performance when required. The working system is in parallel and therefore increases the flow rate and keeps the depression constant as the number of motors in use increases.

Antistatic device

Device that avoids the annoying electric discharges generated by the rubbing of the dust at high speed against the parts of the vacuum cleaner that are discharged on the operator even through plastic material.

Filtration systems

Bag filter collector

It allows you to filter, collect and retain (with a valve) coarse dirt without dirtying the drum. It is used only for dry residues, also in combination with other thinner filters.

Cloth filter

The texture of the fabric and the shape allow for easy cleaning and reuse of the filter. It is used only for dry residues; in combination with the nylon filter you can work longer without having to clean it.

Cartridge filter

The shape with continuous folds arranged in a circle, allows a greater filtering surface in a small space. More autonomy of work with a fine filtering. It is used only for dry residues and is reusable.

HEPA cartridge filter

Thanks to the particular conformation of the filtering material, the HEPA filter is able to retain impurities even as small as 0.3 microns with an efficiency of 99.97%

Washable cartridge filter

It combines all the advantages of the cartridge filter with the practicality of use with both dry and liquid residues. It can also be cleaned with running water

Power tool socket

The presence of the electric socket on the extractor allows you to connect any electric tool. The vacuum cleaner turns on and off automatically when the connected power tool is used or turned off. Suction shutdown is delayed to collect residual dirt in the ducts. Maximum productivity, energy savings and ease of use.

Shake filter

Free the filter from dust without having to open the vacuum cleaner; maintaining constant maximum suction power. It can be manual, semi-automatic or automatic.

Cyclonic Aspiration

The dust enters tangentially into the filter chamber and rotates quickly. Due to the centrifugal force and gravity, the powders screw into the collection drum without approaching the center. To limit and delay the contact of the dust with the filter, a cylindrical protection with shark gill slits is placed around it. The lower part, completely open, allows to reduce the speed of the rising air towards the filter. This system allows you to keep the filter clean longer even with the finest dust.

Automatic ejection of liquids

The flow inversion system (with the filter shaker inactive) brings the entire aspirator to pressure. This allows liquids to be compressed and expelled comfortably through the tap located at the base of the drum.

Vacuum cleaners and safety

They are fully certified vacuum cleaners (not only the filter, but the entire machine) to comply with the European directives that regulate the suction of dust that is harmful to health (asbestos, preserved and fertilizers) and explosive dust (aluminum, wood, flour) .

Suction certificate in CLASS L

Moderate Hazard Dust - Vacuum filter traps over 99% dust with a grain size of less than 2 microns

Suction certificate in CLASS M

It is the ability of the vacuum cleaner to retain 99.9% of all dust extracted with OEL higher than 0.005 mg / m³.

Some examples of these powders that can be retained with these vacuums are processing residues of: wood, copper, platinum, nickel, insecticides and pesticides, manganese etc. (some of these substances are also carcinogenic)

Suction certificate in CLASS H

It is the ability of the vacuum cleaner to retain 99.995% of all dust extracted with OEL higher than 0.005 mg / m3.

Some examples of these powders that can be retained with these vacuum cleaners are processing residues of: lead, bacteria, molds, germs (present in hospital renovations), cadmium (accumulators and anti-rust), chromate potassium (matches and pencils, impregnating agents for wood, printer ink), etc.

Type 22 class vacuum certified

Machine completely certified according to ATEX regulations for use in zone 22 and to contain dangerous dusts (class M). The classification of the areas in which the products will be placed, with reference to the ATEX regulations and updates, must be made by the purchaser.

ATEX vacuum certified

It is the possibility of the vacuum cleaner to work safely in areas where potentially explosive atmospheres may be present. This certificate guarantees the positioning of the machine not the possibility of sucking up potentially explosive dust. For that you need a Type 22 certified machine.

Household and Semi-professional Vacuum Cleaner

From the low cost, the vacuum cleaners offered by Indors, although very cheap, maintain a level of quality high enough to guarantee a good functioning for all those classic household jobs. For DIY, to clean the garage or the stove at home, these vacuums are a valid choice.

Wide range of professional vacuum cleaners for general vacuuming in the workplace. The professional vacuum cleaners we have selected are designed to last over time. Indors offers vacuum cleaner bins of all sizes, powerful, silenced, made to satisfy any type of need.

Vacuum Cleaner for Fine Dust

Useful professional vacuums where the amount of dust to be vacuumed is elevated, such as in vacuuming with power tools in drilling, sanding and cutting work on construction sites or in your own laboratory. Some of these professional vacuum cleaners can even work continuously thanks to the automatic filter shakers they are equipped with. Furthermore, special filters make these vacuum cleaners certified to be used with highly harmful powders (asbestos, platinum, nickel, etc.).

Industrial vacuum cleaner

Used for industrial work, industrial vacuums are capable of providing top-level performance. Advanced technologies such as automatic filter shakers, cyclonic effect and special filters make industrial vacuum cleaners suitable for the most diverse and demanding needs. The larger models have a capacity of 100 liters of tank. Therefore ideal for vacuuming large quantities of vacuumed material.
