Centrifugal fans are great for industrial applications that require moving air because they offer a great deal of efficiency and are highly versatile. However, it's important to put some thought into which type of centrifugal fan is ideal for your application to maximize the efficiency of this industrial device.
The following are five of the most common kinds of centrifugal blower out there and a brief explanation of what situations they're best for:
Backward inclined blower
A backward inclined blower is good for providing general ventilation functions and also collecting dust. This type of blower offers a horsepower curve that's designed to be non-overloading and it's not quite as noisy as some of the other types of blower listed here.
Where durability is an important consideration, a backward inclined blower can be chosen to handle higher volumes of air and to exceed the durability of airfoil blowers.
Radial blade blower
For air movement applications requiring material handling and an overloading horsepower curve, radial blade blowers are often the most appropriate option. Radial blowers offer medium airflow and are perfect for dusty environments or industrial atmospheres where exposure to moisture is inevitable.
It's important to note that radial blades tend to be on the noisy side in comparison with other common types of centrifugal blower. They therefore might not be the best choice if you're trying to keep noise down at your facility.
Airfoil blower
An airfoil blower doesn't make a lot of noise during operation, but it also is only suitable for working in clean air situations. A few of their key features include high efficiency operation and a non-overloading horsepower curve.
Forward curve blower
A forward curve blower is a centrifugal blower that operates at medium pressure and offers high airflow. Like airfoil blowers, forward curve blowers are appropriate for operating in clean air environments. However, they also work well with both exhaust and ventilating applications.
Forward curve blowers tend to be among the quieter centrifugal blowers and they feature overloading horsepower curves.
Backward curve blower
Backward curve blowers are perhaps the quietest types of centrifugal blower out there. They are suitable for high volume and low pressure situations.
Like airfoil blowers, backward curve blowers should only be used in clean air settings. Another similarity backward curve blowers share with airfoil blowers is that they are also non-overloading horsepower curve blowers. Backward curve blowers offer a fairly high level of efficiency.
