A roots blower is a valve-less displacement compressor without internal compression. When the compression chamber comes into contact with the outlet port, compressed air flows back into the housing from the pressure side. Subsequently, further compression takes place when the volume of the compression chamber further decreases with continued rotation. Accordingly, compression takes place against full counter-pressure, which results in low efficiency and a high noise level. Two identical, usually symmetrical, counter-rotating rotors work in a housing, synchronized by means of a set of gear wheels. Blowers are usually air-cooled and oil-free. Their low efficiency limits these blowers to very low pressure applications and compression in a single stage, even if two- and three-stage versions are available. Roots blowers are frequently used as vacuum pumps and for pneumatic conveyance.
Airus Roots blowers, also known as roots blowers or rotary lobe blowers, offer several advantages in various industrial and commercial applications:
1. High Volume, Low Pressure:
Roots blowers can efficiently move large volumes of air at relatively low pressures, making them suitable for applications such as aeration, pneumatic conveying, and ventilation.
2. Oil-Free Operation:
Many roots blowers are designed for oil-free operation, making them ideal for applications where oil contamination must be avoided, such as in food processing or pharmaceutical manufacturing.
3. Sturdy and Low Maintenance:
Roots blowers are typically robust and have a simple design, requiring minimal maintenance. This makes them reliable and cost-effective over the long term.
4. Constant Airflow:
They provide a consistent airflow, which is useful in applications such as wastewater treatment, combustion air supply, and industrial vacuum systems.
5. Energy Efficient:
Modern roots blowers are designed to be energy-efficient, helping to reduce operational costs and environmental impact.
6. Wide Range of Applications:
Roots blowers are used in diverse industries including wastewater treatment, chemical processing, power generation, and pneumatic conveying due to their versatility and reliability.
Overall, the advantages of Roots blowers make them a popular choice for various industrial and commercial air handling applications.
