The Difference Between Roots Blower and Centrifugal Fan by Xianrun Blower

The Difference Between Roots Blower and Centrifugal Fan by Xianrun Blower

1. Different working principle, centrifugal blower impeller is forward curved impeller or backward curved impeller. The air is exhausted from casing by centrifugal force. 
While roots blower impeller is two rotor, and the interval is very small. The air is exhausted from casing by the two impeller extrusion.

2. Different working pressure, roots blower outlet air pressure is much higher than centrifugal fan. 

3. Different airflow. In general, roots blower is suitable for higher pressure and smaller airflow situation, while centrifugal fan is suitable for larger airflow and lower air pressure situation. 

4. Different manufacturing accuracy, roots blower is more precision, and has more strict matching requirements.

Under the synchromesh gear drive, the air goes along the inner shell wall from air inlet to the discharge side. Roots blowers are always used in aquaculture, waste water treatment, and increasing oxygen aeration, transporting biogas, cement conveying and so on. 

High Capacity Double Suction Fans for Power Plant

While centrifugal fan is depending on the input mechanical energy, to improve the air pressure side by side to exhaust air out, so centrifugal fan is a kind of driven fluid machinery.

Coupling Driving FD Fan with High CFM

Centrifugal fan is widely used in factories, mines, tunnels, cooling towers, vehicles, ships, these structure of ventilation, dust and cooling system; 
and the ventilation of the boilers and industrial furnaces, kilns and so on.

Casing: 
Casing is mainly used to support the wallboard, impeller, mufflers and fix them.
Wallboard: 
To connect casing and impeller, and support the impeller rotation, and have end face sealing effect.
Roots Blower Impeller: 
Impeller is rotating part of the roots blower. Roots blower is divided into two lobes roots blower and three lobes roots blower. Compared with two lobes roots blower, three lobes roots blower has the features of small gas pulsation, low noise, stable running and so on, so three lobes roots blower gradually replace two blades roots blower.

Positive Displacement Roots Blower

Silencer: 
To reduce the gas pulsation noise in air inlet and outlet of roots blower. 
Safety valve: 
To restrict the roots blower booster operation. 
Back-pressure valve: 
To prevent the roots blower counter-rotating when the roots blower shutdown load. 
Pressure relief valve: 
According to different requirements, pressure relief valve is used in roots blower no-load startup. 
Sound proof enclosures: 
To satisfy and meet the required noise to the environment.
