A1 Blowers’ Roots-type air blowers are designed to deliver a continuous and steady airflow at the required pressure. These high-performance blowers feature robust construction, require minimal maintenance, and operate without noise or vibration. They are ideal for applications where a reliable air supply is essential for continuous, 24/7 plant operations.
What is a Roots-type air blower?
A Roots-type air blower is a positive displacement blower in which two rotors rotate in opposite directions within a specially designed casing. As the rotors turn, air is trapped between the rotors and the casing, moving it from the inlet side to the discharge side. Unlike centrifugal blowers, Roots blowers deliver high-pressure air within their rated range, making them ideal for STP, ETP, and WTP plants that require continuous (24/7) airflow at a constant pressure. These blowers are widely used in industries where a reliable supply of oil-free air and continuous operation are essential.
How Does a Roots Air Blower Work?
The operating principle of a Roots Type Air Blower is simple and reliable.
Air enters the blower through the suction inlet.
The two rotors rotate in opposite directions.
A fixed volume of air becomes trapped between the rotor and casing.
The trapped air is carried toward the discharge outlet.
Air is delivered continuously into the connected pipeline or process.
The rotors do not normally come into direct contact with each other or the blower casing. Proper clearances allow smooth operation while reducing mechanical wear.
The blower’s actual performance depends on factors such as blower size, rotational speed, pressure, temperature, system resistance, and motor selection.

Applications of Roots Type Air Blower
Roots blowers are used in a wide range of industries and processes.
1. Sewage Treatment Plants (STP)
In sewage treatment plants, Roots blowers supply air to aeration tanks. The air supports the biological treatment process by providing oxygen to microorganisms that help break down organic matter.
2. Effluent Treatment Plants (ETP)
ETP systems often require continuous aeration for biological wastewater treatment. Roots Type Air Blowers can provide the required airflow to aeration tanks and related treatment processes.
3. Water Treatment
Roots blowers are used in various water and wastewater treatment applications where continuous air supply is required.
4. Aquaculture
Aeration is essential in aquaculture systems for maintaining dissolved oxygen levels. Roots blowers can provide continuous air to fish and shrimp farming systems.
5. Pneumatic Conveying
Roots blowers can be used for conveying powders, granules, and other dry materials through pipelines using positive-pressure or vacuum conveying systems.
6. Biogas Plants
Roots blowers can be used for gas handling and other air or gas movement requirements in biogas and renewable-energy applications, subject to suitable blower selection and gas compatibility.
7. Industrial Aeration
Various manufacturing processes require continuous air for aeration, agitation, combustion support, or process operations. Roots blowers can be selected according to the required operating conditions.
8. Cement & Construction Industries
Roots-type blowers are commonly used in applications such as silo aeration, pneumatic conveying, and material handling.
9. Food & Beverage Industry
They can be used in pneumatic conveying and process-air applications where an appropriate hygienic and application-specific blower configuration is selected.
10. Chemical & Process Industries
Roots blowers can support air movement, aeration, pneumatic conveying, and other industrial processes depending on the application.

Frequently Asked Questions
What is a Roots Type Air Blower?
A Roots Type Air Blower is a positive displacement blower that uses two rotating lobes to move a relatively fixed volume of air from the inlet to the discharge side.
Is a Roots blower suitable for STP?
Yes. Roots blowers are widely used for aeration in sewage treatment plants because they can provide continuous airflow required by biological treatment processes.
The compression chamber of a conventional Roots blower is designed so that lubricating oil does not enter the air compression path. However, the complete blower system should be selected and maintained appropriately for the required air-quality specification.
They are used in wastewater treatment, sewage treatment, aquaculture, pneumatic conveying, industrial aeration, cement handling, biogas-related applications, and several other industrial processes.
How do I select a Roots blower?
The main parameters are required airflow, operating pressure, application, operating temperature, altitude, gas characteristics, duty cycle, and installation conditions.
What is the difference between a Roots blower and an air compressor?
A Roots blower is primarily designed to move a large volume of air at relatively low to moderate pressure compared with many compressors. Air compressors are generally designed to achieve substantially higher pressures.
Can a Roots blower run continuously?
Yes, Roots blowers are commonly used in continuous-duty industrial applications when correctly selected, installed, ventilated, and maintained.
