Process fans are one of the key components of an Industrial manufacturing plant. Industrial process fans serve a significant purpose by improving the efficiency of a whole variety of industrial activities. Having the right type and number of process fans in factory helps to not only improve efficiency and manufacturing capacity it also helps in maintaining a comfortable and safe environment for workers.

There are different types of fans that are used in an industrial set up. When you are in the process of finalizing the manufacturing plant layout design, you need to keep in mind which kind of fan would be more apt in a given situation. Would it be the direct drive kind of a fan, or the belt line variety of an industrial fan?

Let us look at both these types to understand the nuances and the reasons for picking one over the other.

Belt Drive FanIn case of a belt drive fan, the motor is independent of the blades of the fan. Moreover, at least one of the belts, or sometimes more, would connect the motor of this industrial fan to the moving parts of the fan.

Now, let us look at some of the benefits of going with this kind of a fan. To begin with, industrial fans that are belt driven offer a greater level of flexibility, when it comes to determining the RPM speed of a fan. These fans usually tend to be cheaper than a direct drive industrial fan of the same dimension and size.

Having said that, there is a slight disadvantage tagged with this kind of an industrial fan as well, and that is, there tends to be greater friction between the moving parts of this kind of a fan. This friction could possibly lead to a higher energy cost as well as a higher rate of maintenance.

Direct Drive FanThe other kind of industrial fan is the direct drive fan. In case of a direct drive industrial fan, the motor of the fan that is in control of the movement of the blades of the fan is either connected to a fan axle or a shaft. This ensures that this kind of industrial fan rotates at more or less the same speed as the motor. So, the motor and the fan rotating at the same speed is definitely a plus here, when it comes to choosing this kind of an industrial fan.

Coming to the advantage of this kind of an industrial fan, the biggest advantage is greater efficiency. Unlike the belt driven fans, in case of a direct drive fan, there is lesser energy loss. This is because of the fact that the amount of friction is greatly reduced in case of this fan, when the fan is operating. More often than not, the maintenance cost of this kind of fan is also comparatively lower. Hence, this fan happens to be a more popular choice for industrial set ups, when compared to belt drives.

Choosing a Belt Drive Fan or Direct Drive Fan for an Industrial ProcessWhen choosing a suitable industrial fan, consider flexibility, energy efficiency, and maintenance costs while making a decision. Belt drive fans and direct drive fans have their advantages and limitations. It is important to choose the correct type based on the objective assessment of that specific industrial process.
