Axial Flow Fan Vs Centrifugal Fan
The alternative option for an industrial fan is a centrifugal fan.
Axial flow fan vs centrifugal fan. F wheel curved forward blades. 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. 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.
A centrifugal blower uses centrifugal forces to rotate the blades. To create the air radial fans first pull it into the fan. Axial fans move a lot of air from place to place when working against little pressure. History of centrifugal fans.
This type of blower is primarily used in ventilation systems. Use of axial fans in the low pressure range up to 100 mm. Alexander sablukov a military engineer with the. This is often done via a side intake which varies based on how the size of the fan.
Airflow is directed through a duct which creates a higher pressure air flow than an axial fan despite its lower flow rate. Axial vs centrifugal fans. Mixed flow fan in the impeller of the fan the direction. Centrifugal fans radial fans in a centrifugal fan the air flows is in a radial direction relative to the shaft.
To help clear up that confusion here is a breakdown of the fan types their benefits and their uses. Check out some quick facts on centrifugal fans to see if it s right for you. 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 fans are suited for relatively large volumes compared to pressure.
Centrifugal fans create a steadier flow of air but also require more power to run. Also known as centrifugal fans radial fans don t pull air parallel to the axis as axial fans do. Centrifugal fans also referred to as blowers and squirrel cage fans because they resemble a hamster wheel were invented in 1832 by lt. There are two primary varieties of fan axial fans and centrifugal fans.
These negative aspects are opposed to a lower weight less space and lower cost. The centrifugal fan was invented in 1556 to ventilate mines. Regardless both types of fans are used for industrial applications. Instead they move air from the center radially hence their name.
The axial flow fan is well known around the average household as a ceiling fan. Axial flow and centrifugal flow classifications. Axial flow fans centrifugal fans mixed flow fans crossflow fans next we will briefly introduce some common fans in hvac system.
