Roots Blower - Types & Works of Roots Blower

Roots Blower Rotary positive blower is also known as positive displacement Roots blower (PD Roots blower). The mechanism of blower is unique and much traditional use from years of time. The roots blower design was first time patented in 1860 by Philander Higley and Francis Marian Roots. Based on the name of the scientist, the blower is recognized as roots blower.

How Roots Blower Works-

The executing mechanism of blower is intake the air from inlet and dual impellers rotating in different directions trap the air during the rotation between the casing and impeller and discharge at the outlet. The equipment throws the consistent volume of gas to the outlet without discharge thus roots blower is unique compare to compressor. The gas blowing capacity of roots blower depend on the size of casing and rotating part. The air pressure of thrown gas is constant without any change. There is the feature that can operate the blower at high pressure with RAM Types of Roots Blower


Roots Blower are used where needs to blow large volume of air with constant pressure. Single roots blower can blow up the air at limited pressure. Twin lobe roots blower can pump the air with increased pressure at constant rate. High volume low pressure air is achieved from positive displacement pump. These PD types’ blowers are mechanically distributed based on application mechanisms like small PD type roots blowers that generate variable pressure and vacuum capacity. Large PD type roots blower are used in oil & gas production with variable size. Tri Lobe roots blower is faster than normal twin lobe root blower with additional pumping capacity of one more blower into the system. There are various types of roots blower categorized as air cooled blowers and water cooled roots blower are manufactured by the air equipments provider company with varying capacities from 10 M/Hr to 14000 M/Hr.

Parameters to check for selecting efficient Roots Blower

-Twin lobe/Tri lobe roots blower should be made up of good quality sturdy parts for rugged operation.

-There should not be the machine vibration during operation execution that may inferior the blowing capacity of the machine.

-The roots blower must be power saving unit continuing the function for long period with low electricity consumption.


-The resulted air blow should be oil free that depends on machine to work properly to generate oil free conveyance.

-The roots blower should be capable to handle overpressure and vacuum condition. If you are looking for standard quality air equipments like twin/tri lobe roots blower, dewatering system, gas booster, dust collection system for pollution control and other industrial machineries.
