PB 42 Twin Lobe Air Blower(RPM - 1200) 0.7 Kg/cm2:- Twin Lobe Air Blower is also known as a positive displacement Roots blower (PD Roots blower). The mechanism of the blower is unique and much traditionally used for years of time. The roots blower design was first time patented in 1860 by Philander Higley and Francis Marian Roots. Based on the scientist's name, the blower is recognized as a root blower.How Roots Blower Works-The executing mechanism of the blower is to intake the air from the 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 a consistent volume of gas to the outlet without discharge thus roots blower is unique compared to the compressor. The gas-blowing capacity of the roots blower depends on the size of the casing and rotating part. The air pressure of thrown gas is constant without any change.Twin Roots Blower are used where needs to blow large volume of air with constant pressure. Single roots blower can blow up the air at little pressure. The twin lobe root blower can pump the air with increased pressure at a constant rate. High volume low-pressure air is achieved from a positive displacement pump. These PD types of blowers are mechanically distributed based on application mechanisms like small PD-type root blowers that generate variable pressure and vacuum capacity. Large PD-type root blowers are used in oil & gas production with variable sizes.
