The Vane Axial Fan

The axial fans are mainly used in applications that have been designed to exchange heat through environmental air. These may include the air-cooled condensers or the air cooled heat exchangers. A number of industries use these fans in the package cooling towers where they are incorporated in the heating ventilation and air conditioning systems. They are available in very many configurations depending on the type of material.

The vane axial fans are known to be some of the most efficient axial fans in in the market. The fans have been designed with the straight ending vanes that can improve their efficiency and pressure capability. Their blades have an airfoil shape and they can be used for both high and medium pressure applications.

They are a perfect choice for the HVAC systems since they can achieve a good downstream in air distribution. They are compact and robust.

There are a number of reasons why most industries prefer vane axial fans to other types of fans and these include:

1. These fans are mainly used for both medium and high pressure applications. This is a common scenario in most industrial settings. It is for these reason that they are used in crucial applications such as the induced draft services in the boiler equipment.
2. The fans have been designed with a low rotating mass. This makes it easier to achieve high speeds within a very short period of time. Furthermore, these fans can generate air flow in the reverse direction. It is for this reason that these fans are used in a number of ventilation applications.
3. The fans can be coupled directly to the motor shafts
4. This fans is energy efficient considering that it can attain up to 85% energy efficiency. This essential feature has been attributed to the airfoils and clearance.

These are some of the main reasons why a good number of people opt for these fans as opposed to other fans in the same category such as the propeller and the tube axial fans.

To enjoy all the above benefits, the consumer will have to pay more money to acquire a vane-axial fans with the same specifications as the propeller fan. Therefore, it is upon the end user to conduct a cost benefit analysis.

Remember, you can opt for a propeller fan and pay more when it comes to the operational costs. On the other hand, you can invest more money to purchase a vane axial fan and save more on the operational costs. You need to balance all the two aspects.
