Twin/Tri Lobe Roots Blower

RPE takes pride in its range of Twin Lobe Roots Blowers, offering a versatile and comprehensive lineup with capacities ranging from 10 cubic meters per hour (CMH) to an impressive 10,000 CMH. These blowers are designed to handle various industrial applications, providing robust and efficient air and gas handling solutions.

What sets RPE’s Twin Lobe Roots Blowers apart is their ability to deliver exceptional performance even under challenging conditions. With a maximum differential pressure of 1 kg/cm², these blowers excel in applications requiring substantial pressure generation, such as aeration in wastewater treatment, pneumatic conveying, and more.

RPE’s commitment to precision engineering ensures that our Twin Lobe Roots Blowers are built to last, with minimal maintenance requirements. Whether you need a reliable solution for large-scale industrial processes or smaller applications, our versatile range of blowers has you covered.

Description

The two rotors rotate in opposite directions.

As each rotor passes the blower inlet, it traps a definite volume of air/gas and carries it around the casing all the way to the blower’s outlet. With constant speed operation, the displaced volume remains approximately the same at different inlet temperatures, inlet pressures, and discharge pressures.

As each rotor passes the blower outlet the air is compressed to the system pressure there and expelled.

There exist finite clearances between every part inside the casing of the blower, which allows operation without lubrication being required inside the casing, and hence the blower provides 100% oil-free air at the discharge end.

Timing gears control the relative position of the rotors to each other.
