A radial-type fans are belonging to the brand, which contains the wheels in their design with rebel. As a rule, they have a high efficiency, and during operation there is no discomfort from the noise of their motor. Van® trademark was first registered in 2008 and from that time it is considered a sample of comfort and modernity. Each fan is manufactured using the most recent technical developments, as well as the latest equipment. Cutting of all composite products (blades, wheels for wheels, housing walls) is performed using a laser. But the formation of details of conical and toroidal types is performed using a CNC controlled. In this case, welding wheels are carried out using a special welder robot.

Each body of the ventilation products is made of galvanized steel using sunset technology.

Since the production of fans is carried out on high-precision equipment, the serial products fully corresponds to the reference characteristics declared by the manufacturer. This guarantees constant high quality of each fan. Trademark Van® manufactures its products in 16 sizes, providing the widest choice of device performance, which is in the range of 300-120000 m3 / h, and the pressure indicator is about 2600 Pa.

As a rule, the fans from the Van are used in those systems where the functioning technology requires a high efficiency, low noise level, or a set of multiple fans that will work in parallel to each other. Such products have high technical parametersand can also completely replace the famous fan series domestic production (VC 4-70, BP 80-75, BP 86-77). It is over compared to them, the products of Vran have a number of advantages:

• there are several classes of wheel execution that depend on the size of the circumferential speed. It is the wheels that serve as the basis for the reliable operation of the fan mechanism throughout its entire period of operation. All calculations of the working wheels, which use the finite element method, fully comply with experimental data;
• when choosing engines, the manufacturer optimized power reserves, which, ultimately, allows the use of structures with a small installation capacity, which is particularly important for small numbers fans;
• the use of fans of all numbers, which are made on the first constructive scheme. Each of them contains frequency converters, which makes it possible to accurately correct the mode of operation of the device during commissioning tests, as well as during the further operation of the fan. Developed and successfully implemented a technique for selecting an engine for optimal sizes, which is capable of working with frequency converter and change the frequency range of the current used;
• high aerodynamic performance indicators are provided by a simple design of the wheel, as well as seals, which is between the wheel and the nozzle when used in the design quality technology assembly;
• the shape of the spiral case was slightly changed, due to which the average speed of the air flow is reduced in the output section of the device, the pressure loss in the adjacent ventilation network is also reduced.

The main purpose of the fans Van

Fans can be installed in ventilation systems standard type, as well as in the air conditioning system and air heating Buildings in production or in residential premises. To travel during two hours gas-high mixesThe temperature of which is within 400-600 ° C, could not harm the fan, it is manufactured using special VANA® type versions) Du.

Fans are such types of versions:

• general industrial, which manufacturer, as a rule, marks the sign "H";
• heat-resistant, which are labeled as "F";
• anti-corrosion (K1), which may interfere with the formation of corrosion and rust;
• corrosion-heat resistant (k1zh) - such fans combined two types of mechanisms and their properties;
• explosion-proof (marking type "B") - products are performed according to only the first constructive scheme;
• heat resistant, the mechanism of which has protection against explosions (VZH) - execution similar to the previous type of fans;
• fans that have a protective mechanism from the explosion and corrosion formation (VK1; VK3);
• explosion-proof corrosion-heat resistant (VK1ZH);
• fans are resistant to seismic activity that can be easily combined with other types of versions that are listed above.

  Mechanism of fans from within

  In its design, each fan has a impeller, which rotates both in and counterclockwise. Wheel blades have a special shape and bent slightly backwards. The spiral body of the device is also able to rotate. Fan mechanisms are manufactured both in the first and fifth structural scheme according to the adopted 5976 GOST standards.

The fans performed according to the first structural circuit, are directly connected to the engine and there are two modifications of the VANR6 type and vran9. They differ in the number of blades of their impeller.

Fans, which belong to the fifth structural pattern, in its design contain a belt type drive. Such products are only one version modification. Unlike it, Vran9, which belongs to the first constructive scheme, is equipped with engines, thanks to which you can perform a frequency of speed control.
For the climate execution devices of types U1, UHL1, T1 in the design of the mechanism is provided additional protection From atmospheric precipitation, which is equipped with a drive and exhaust part of the fan.

Fans that are used on large industrial enterprises, have a noise insulating casing, which makes it possible to largely reduce the noise level of the device to a value of 12 dB. In this case, the overall sound pressure level decreases by 25-30 dB at a distance of 5 meters.

If desired, the Customer may acquire additional components in the form of vibration insulators and flexible inserts that allow reduced dynamic loads. It will not be superfluous: reverse action flanges, frequency converters, and various devicesthat allow you to perform smooth start Fan.

Operational conditions
According to the operational rules and standards, so that the fans can serve their owner for many years, they must be installed outside the zone in which people are constantly being.

Products on the provisions of GOST 15150 are able to withstand a variety of climatic working conditions, ranging from moderate, and ending with a tropical climate.

Basic operating conditions:

the temperature around the device must match:
- "-" 45 - "+" 40 degrees Celsius for a moderate climate type;
- "-" 60 - "+" 40 degrees - for a moderately cold climate;
- "-" 10 - "+" 50 degrees - for tropics.
At the same time, the average value of the so-called vibrationability of all external mechanisms, which serve as a source of vibration oscillations, should be within 2 mm / s.

Design

The main element of the fan design is the impeller with blades, bent back. The wheel is placed in a rotary spiral case. The inlet nozzle of a special cylindrical shape is placed outside the wheel, which ensures durability. The input flange is also not provided, due to which the air inlet on the suction side is more favorable. To protect the engine from atmospheric precipitation there is a separate mechanism. Engine three-phase asynchronous single-speed. Models Vran9 on the 1st scheme can be equipped with a drive with frequency control of the speed of rotation. Fans are able to operate in smoke mode or in the combined smoke and ventilation mode - in such models installed engines for a long continuous operation.
