To choose a ventilation unit that will meet your needs and be efficient, there are a few important criteria that you must take into account when purchasing. Among the most important criteria that exist we have chosen to talk to you about power, air flow, safety, functions and maintenance.
The type of fan
There are several types of fans classified into several categories namely: axial or helical fan, radial or centrifugal fan and bladeless fan. These different categories of fans each have a specific operation and are used in various cases.
The operation of the axial fan is as follows: the air is sucked in parallel to the axis of rotation of the blades and is ventilated in the same direction. The axial fan is capable of generating a large flow of air. While it is true that most models of this type of fan are noisy, it is indeed possible to find models of quiet axial fans. This type of fan can have an efficiency of up to 90%. It is used in households in various forms: wall fan, table fan, or the best stand fan in India. It also comes in the form of powerful air fans used in warehouses. Its use can also extend to the industrial field.
Like the axial fan, the centrifugal fan draws air parallel to the axis of its rotor. On the other hand, the centrifugal fan propels the air perpendicular to the axis of its rotor. This type of ventilator, also called column ventilator, is known to be quiet and easy to store due to its elongated shape. Although this type of fan is not really powerful, it is used in various sectors of activity including maritime, industrial and domestic. The centrifugal fan can be used in an air conditioning or air distribution system.
The third category of fans differs from the other categories by the fact that it does not have visible blades. The bladeless fan is a very recent category of ventilation device. This category has a futuristic look and is composed of an elongated support that acts as a foot and a circular, oval or elongated part. The bladeless fan is most often used for household purposes.
The type of use
The frequency of use of a ventilator varies depending on the user. Some make regular use of their ventilator while others make occasional use. For those who wish to use their ventilator at a high frequency, it is recommended to opt for a device which has a good efficiency. It is also important that the fan does not consume electricity at the risk of skyrocketing the electricity consumption of the household or business.
The choice of a fan must also be made according to the size of the room to be ventilated. To ensure good ventilation in a large room, it is necessary to opt for a large fan. If you want to ventilate a room with an area of about 25 square meters, an air flow of just over 100 cubic meters per minute is recommended. However, for optimal use of a ventilator’s air flow, the unit must be placed in a strategic location. This is particularly useful for distributing the air evenly in the room.
Power and air flow
Power and air flow are two parameters that go hand in hand. The power is linked to the fan motor and determines the speed of rotation of the rotor to which the blades are attached. Power is expressed in watts (W). Regarding the air flow, it expresses the quantity of air propelled by the fan and is expressed in cubic meters per hour (m 3 / h) or in cubic meters per minute (m 3 / min). A powerful motor allows for a high air flow. As fans have multiple speeds, the power and airflow of a fan can be increased up to a certain level by selecting a speed. The user can therefore select according to his needs a strong ventilation or more moderate ventilation.
Noise level and aesthetics
The sound level of a fan is an important parameter for good user comfort. It is measured in decibels and measures the noise of the device. Before purchasing a fan, it is necessary to find out about the sound level of the model you want to choose. A fan that rumbles like a turbine is unpleasant and its use ends up being a torment, especially when you need quiet sleeping or concentrating. Conversely, a silent fan gives you fresh air and silence for your greatest pleasure. The sound level becomes unpleasant when it greatly exceeds 60 decibels. However, there are silent fans with a noise level of about 35 decibels.
Regarding the aesthetics of a fan, it depends among other things on its color and its design. The aesthetics of the fans are variable. So, there are fans of all shapes and colors. Blades with blades can be circular, square, elongated like a tower, or composite with an elongated bottom and a rounded top. The design of bladeless fans is generally made up of an elongated foot and an upper part called the “amplifier ring” of very different shapes to satisfy a maximum of tastes. In addition, the aesthetics of a fan partly influence the ventilation of the device. Column fans that have an elongated shape let the user feel the ventilated air from head to toe.
Fans have more and more features that improve the comfort of their users. The most sophisticated models of fans combine a wide range of digital and programmable features. These models are equipped with a remote control that allows you to activate features without having to move from your seat. It is therefore possible to increase or decrease the speed of rotation of the fan blades remotely. Some models also have buttons for choosing different speeds, a turbo boost button which considerably increases the rotational speed of the blades to generate an even greater air flow. In order to make judicious use of the air flow produced by the fan, it is possible to activate the function which allows the upper part of the fan to oscillate. The oscillation of the fan allows to widen the spectrum of diffusion of the air in the room for a more equitable ventilation.
A fan can also be equipped with a timer to program its automatic shutdown after a certain period of operation. This feature is useful, for example, if you want to stop the fan at a time that coincides with your sleep. There is also a “night” function which gives you the possibility to adjust your fan so that its operation does not disturb your sleep. You can also benefit from the mist or humidifier function of a fan. With this function, your fan cools and softens the air in your home when it is dry by humidifying it. For this, the fan must be equipped with a water tank. The fogger function can be used both in an enclosed space and in an open space. It is also possible that your fan performs the function of ionizer. This consists in balancing the quantity of negative and positive ions contained in the air in order to purify it. Ionization improves the well-being of a ventilator. The fact that these different functions are programmable considerably facilitates their use.
