Axial Flow Fan Vs Centrifugal Fan

A centrifugal blower uses centrifugal forces to rotate the blades.

Axial flow fan vs centrifugal fan.

F wheel curved forward blades. Centrifugal fans radial fans in a centrifugal fan the air flows is in a radial direction relative to the shaft. Use of axial fans in the low pressure range up to 100 mm. The axial flow fan is well known around the average household as a ceiling fan.

Axial fans move a lot of air from place to place when working against little pressure. Centrifugal fans create a steadier flow of air but also require more power to run. Centrifugal fans also referred to as blowers and squirrel cage fans because they resemble a hamster wheel were invented in 1832 by lt. Regardless both types of fans are used for industrial applications.

Blades mounted to the circular fan hub spin essentially catching the incoming air and throwing it away from the hub at a 90 angle. The motor spins blades around a hub which moves air parallel to the axis of rotation. Centrifugal fans can be classified by their wheel like. Airflow is directed through a duct which creates a higher pressure air flow than an axial fan despite its lower flow rate.

To create the air radial fans first pull it into the fan. Mixed flow fan vs axial fan vs centrifugal fan generally most fans or blowers can be categorised into one of four fundamental types which are named in relation to the direction of flow through the impeller. Axial flow and centrifugal flow classifications. The alternative option for an industrial fan is a centrifugal fan.

Although there are some similarities between centrifugal fans and axial fans there are also distinct differences. Mixed flow fan in the impeller of the fan the direction. Also known as centrifugal fans radial fans don t pull air parallel to the axis as axial fans do. History of centrifugal fans.

The axial fans are much more noisy it often happens that to contain noise the axial fan requires the use of silencers where there would be no need for a centrifugal fan. Check out some quick facts on centrifugal fans to see if it s right for you. Alexander sablukov a military engineer with the. There are two primary varieties of fan axial fans and centrifugal fans.

Axial flow fans centrifugal fans mixed flow fans crossflow fans next we will briefly introduce some common fans in hvac system. Instead they move air from the center radially hence their name. To help clear up that confusion here is a breakdown of the fan types their benefits and their uses. The centrifugal fan was invented in 1556 to ventilate mines.

Pti a global leader in fan technology for more than 25 years manufactures both axial and centrifugal fans. Axial fans are suited for relatively large volumes compared to pressure. Axial vs centrifugal fans.
