Industrial blower: device features, operating principle, popular types
Blowers are air injectors used for industrial purposes. These devices go by various names, including low-pressure compressors, swirl fans, and side devices. Industrial blowers are used in a wide variety of applications. Before purchasing a model, you should understand the operating principles of blowers and their characteristics.

Blower Features
Devices are necessary for pumping and pumping gases. Various works are carried out with them that require strong air. Unloaders are located between powerful fans and compressors. Blowers create a vacuum of 10-50 kPa, which makes the equipment more versatile.
Features of the blower.
Types of equipment
Drawings are used in medical institutions. They are used to transport air purification equipment. There are different types of equipment
Type of equipment.
Electrical
Electric leaf blowers are characterized by the presence of an electric motor. The advantage of the equipment is that the speed can be increased. Two torque options are used – belt and coupling. Important equipment parameters include pressure, power and power consumption. An important criterion when choosing equipment is the ability to regulate the outlet pressure. To prevent failures when the current power in the network drops, a voltage regulator is used.
Vortex
A vortex mechanism operates in pump and injection mode. The principle of operation of the device is based on twisting the air flow into a spiral, which allows you to create a vacuum. The movement is generated using centrifugal force. The pressure in the device increases, and the mixture is removed from the cavity through the outlet.
Borsal devices are required to provide a deep vacuum. The advantages of the devices include low noise level, absence of pulsation and compact dimensions. The models are distinguished by special coatings against the effects of corrosion.
To use the equipment correctly, you need to know the following features
- Availability of an air filter;
- Installing safety valves to block rapid heating of the device.
Rotary
In rotor devices, the air flow is captured by blades. The blades are positioned perpendicular to the gas pressure.
The following items are used in the equipment
- Silencers for vapor purification;
- Valve kits;
- Pressure control mechanisms.
Rotary devices are characterized by compact dimensions and a small number of components.
Blower Operating Principles
The operating principle of industrial retarders is based on compression and displacement of air flow. Depending on the different devices, air is drawn in using a rotor and screw located in the housing.
To operate the device, blades located at certain angles compress the air and direct it into the outlet pipe. The design of multi-stage devices is characterized by the addition of one circle to another. Industrial structures are used in metallurgy and construction.
For stable operation of the device, additional elements are used – valves and filters. This stops the air flow along uneven paths. To protect against rapid warming, cooling devices are installed.

Application
Industrial blowers can save up to 50% energy. When choosing a device, it is necessary to take into account the amount of air consumed by the ventilation station. The devices are used in various technical processes.
Flooding equipment is used in such areas.
- Pneumatic conveyor systems for moving bulk components for household and food use;
- In various buildings to solve problems of engineering systems;
- In the metallurgical industry;
- Construction work during the construction of buildings and road construction;
- Complex processes for cleaning water bodies;
- In agricultural organizations.
Popular manufacturers.
Industrial blowers are produced by a number of Russian and Chinese manufacturers. Domestic devices are assembled in factories and sold to other countries.
Models from famous brands are especially popular.
- Bosch models can operate with air flow at pressures up to 500 mbar. The brand offers equipment with an optimal ratio of quality and price. The devices are used in vacuum and compression modes;
- The domestic company SpetsStroyMash produces high-quality blowers and additional accessories. The equipment is used in the mining industry;
- Atlas Copco devices are highly efficient and reliable. Benefits include efficient use of compressed air. The use of screw equipment is a guarantee against contamination;
- The Italian manufacturer Robuschi offers models for supplying and compressing large volumes of air. The devices are distinguished by reliability, increased performance and natural cooling;
- The Elmo rietschle device is the standard for such devices. Models are used in high pressure installations. They are characterized by durability and performance.
Popular manufacturers.
FPZ models from Italian companies are in particular demand. The organization produces devices of various capacities. The range includes single-stage and two-stage units, as well as equipment for hazardous environments.
The company’s blowers are used to supply air masses up to 700 mbar. High quality elements are used in the production of equipment. These are double-impregnated electric motors, special thermal protection couplings and new generation bearings. Many models are installed vertically. For fastening elements, strong supports are used that are protected from vibrations.
