Power consumption
The maximum power consumed by the fan during operation. The higher the power consumption, the higher, usually, the greater the airflow rate created by the fan, and, accordingly, the higher the performance of the device. On the other hand, power usually directly affects the price, all other things being equal.
Number of speeds
The number of preset speeds at which the fan blades can rotate. The rotation speed is usually set by pressing the corresponding button (in addition, there is also a stepless adjustment, see the relevant paragraph). Most modern models with step adjustment have three preset speeds.
Number of blades
With the same power and blade width, fans with numerous blades can boast of greater air mass distillation performance. However, the formation of a powerful airflow is not affected by the number of blades, but by their
diameter. In addition, the operation of multi-bladed fans is usually associated with an increased level of noise.
Base
—
Cross base. The most common type of base for floor-standing fans, it provides sufficient stability while maintaining a lightweight design. Also, fans with a cross base are usually cheaper than others. Of the advantages, a collapsible design can be noted, which creates additional convenience for storage or transportation.
—
Disk base. This type of base is massive, usually, such discs at the base can weigh 3-5 kg, depending on the fan model. They are made from various materials. Usually, the disk comes as a separate part of the structure, on which a decorative overlay is put on top. It is believed that such a base provides better stability than many cross bases.
—
Tripod. The least common type of base, in which, apart from the aesthetic component, there is nothing else. In terms of structure, such models are too voluminous, and in terms of reliability, they are at the level of models with a disk.
