Roots blowers equipped with impellers consisting of two lobes are referred as twin lobe roots blowers.
Operation of Twin Lobe Roots Blowers
The roots blowers are primarily of the twin lobe configuration and have a pair of impellers with two lobes equipped in each. These are eight shaped impellers rotating in opposite directions on the parallel situated shafts. In these positive displacement or PD type roots blowers the lobes work against the varying pressure to move the air trapped in the spaces between impellers. The impellers in the blower or the air compressor rotate in opposite direction thus carrying the trapped air to the outlet of the compressor.
The impellers rotate at a constant speed at a constant pressure and constant temperature to displace the required volume of air for efficient performance. The volume of air discharged by the blower depends on the speed of the impellers rotating inside the blowers and pressure of the air. The modern air blowers are equipped with the timing gears. These timing gears will control the position of the impellers relative to one another thereby helping to maintain small and definite clearances in between. Therefore lubrication is not required within the air casing in the blower.
As the operation of twin lobe postive displacement roots blower is dependent on the rotation of the impellers these are also referred as the rotary positive displacement blowers at times.
How are Twin Lobe Roots Blowers different from the Tri-Lobe Blowers?
The roots blowers are classified into two categories – twin lobe roots blowers and tri lobe roots blowers. The basic difference between both of them is the number of lobes in the impellers of each. While in the twin lobe blowers there are only two lobes, the tri lobe roots blowers are equipped with impellers consisting of three lobes each. For high pressure and heavy duty applications tri lobe roots blowers are better options than the twin lobe configurations. The tri lobe roots blowers can compress and sweep nearly 6 times the volume of air/gas in a revolution as compared to twin lobe roots blowers.

Applications of Twin Lobe Roots Blowers
Pneumatic conveying system, sewage treatment plants, central vacuum cleaning system, aeration in storage silos, charging of kilns in cement and steel plants, effluent treatment plants and water treatment plants are some of the areas where these twin lobe roots blowers are widely used. These Twin Lobe Roots Blowers are used for numerous applications in cement, steel, aluminum, power, chemical, pharmaceutical, petro-chemical, food processing, dairy, space, textile and construction industries.
Conclusion:
The roots blowers are important equipments in several industries. Their operation is based on rotation of the impellers which are responsible for movement of air for various applications in industries.
