A Roots blower is a type of positive displacement blower used to move a specific volume of air or gas from the inlet side to the discharge side.
The blower generally uses two specially designed lobes rotating inside a casing. As the lobes rotate, air is carried from the inlet toward the outlet. The design allows the blower to deliver a relatively consistent airflow for applications that require continuous air movement.
Roots blowers are commonly used in:
Sewage Treatment Plants (STP)
Effluent Treatment Plants (ETP)
Water Treatment Plants (WTP)
Biogas plants
Pneumatic conveying systems
Industrial aeration systems
Aquaculture
Cement and process industries
Chemical industries
Food processing industries
Industrial vacuum and air applications
Why Choose a Professional Roots Blower Manufacturer?
Selecting the right Roots blower manufacturer in India is important because blower performance depends on several factors, including airflow, pressure, operating conditions, installation and maintenance.
A professional manufacturer can help customers select a blower according to the actual application rather than simply supplying a standard machine.
Important factors include:
1. Airflow Requirement
The required airflow is normally specified in units such as m³/hr, CFM or other applicable flow units.
The correct blower size should be selected according to the required air volume and operating conditions.
2. Operating Pressure
Different applications require different discharge pressures. A blower should be selected according to the application’s pressure requirement.
3. Continuous Operation
STP, ETP and other industrial plants may require blowers to operate for long periods. Therefore, blower construction, cooling, lubrication and installation become important considerations.
4. Application Environment
The environment around the blower can affect its performance and maintenance requirements.
For example, wastewater treatment plants may have humid or corrosive environments, while biogas applications can involve specific gas-handling requirements.
Twin Lobe Roots Blower
A Twin Lobe Roots Blower uses two lobes rotating in opposite directions inside a casing.
The synchronized rotation of the lobes allows the blower to transfer air from the inlet to the discharge side without direct contact between the rotating lobes.
Twin lobe Roots blowers are widely used because of their relatively simple mechanical design and suitability for continuous air-moving applications.
Depending on the application, a complete blower package may include components such as:
Blower body
Lobes
Shafts

Roots Blower for STP Applications
One of the major applications of industrial Roots blowers is Sewage Treatment Plants (STPs).
In biological wastewater treatment, microorganisms require oxygen to break down organic matter. Blowers can supply the required air to the aeration system through pipelines and diffusers.
A typical STP aeration process can involve:
Blower → Air Pipeline → Air Diffusers → Aeration Tank → Oxygen Transfer → Biological Treatment
For this reason, selecting an appropriately sized Roots blower for STP is important for maintaining the required aeration conditions.
A1 Blowers provides Roots blower solutions for wastewater treatment applications based on plant requirements.
Roots blowers are also used in Effluent Treatment Plants (ETPs) and certain water treatment processes.
In ETP applications, the blower may be used for aeration and other air requirements depending on the treatment process.
In water treatment applications, air blowers can be used for processes such as:
