WTP Roots Blower Manufacturer in India – Reliable Air Blowers for Water Treatment Plants
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.
Clean water is essential for various applications, including municipal wastewater treatment, effluent treatment, aquaculture, pneumatic conveying, and Sewage Treatment Plants (STPs) for commercial, industrial, and hotel sectors. STP plants are used to treat this water, and their operation relies on Roots blowers—often referred to as the “heart” of the STP plant. A1 Blowers India Private Limited stands out as India’s leading manufacturer of Roots blowers for STP, ETP, and WTP plants.
The company offers a 2-year warranty, lifetime free inspection support, 24/7 service availability through a pan-India branch network, and manufactures blowers designed for low noise and vibration. Thanks to these factors, A1 Blowers India Private Limited boasts a repeat client rate of over 87% and holds the top position in India for Roots blower manufacturing; indeed, the company is regarded as the “heart” of the STP due to its superior quality and service.
A Roots blower is a positive displacement air blower that moves a specific volume of air from the inlet side to the discharge side with every rotation of its lobes.
Unlike centrifugal blowers, Roots blowers are designed around positive displacement technology. This makes them suitable for applications where a steady and dependable supply of air is required.
A typical Roots blower consists of:
Twin-lobe rotors
Blower casing
Shafts
Bearings
Timing gears
Drive arrangement
Inlet and discharge connections
Lubrication system
Base frame and accessories
The synchronized rotation of the two lobes allows the blower to continuously transfer air from the suction side to the discharge side.
For water-treatment applications, this continuous airflow can play an important role in aeration and other treatment processes.
Why Are Roots Blowers Used in WTP Applications?
A Water Treatment Plant requires reliable equipment because interruptions in the treatment process can affect overall plant performance.
Depending on the WTP process and system design, air blowers may be used for applications such as:
1. Aeration
Aeration introduces air into water to support specific treatment processes and improve oxygen transfer where required.
A Roots blower can provide the continuous airflow necessary for aeration systems.
2. Air Scouring
In certain filtration systems, air is used for cleaning or scouring filter media during backwashing operations.
The blower must be capable of delivering the required airflow at the specified pressure.
3. Biological Treatment Support
In treatment systems involving biological processes, maintaining an appropriate oxygen supply can be critical.
A dependable blower helps maintain the required airflow throughout the process.
4. Continuous Air Supply
Many water-treatment processes operate continuously. Therefore, the blower needs to deliver stable airflow for extended operating periods.
This is one of the reasons twin lobe Roots blowers are widely considered for industrial water-treatment applications.

Key Features of A1 WTP Roots Blowers
When selecting a blower for a water-treatment plant, performance and reliability are two of the most important considerations.
A1 Blowers’ twin lobe air blowers offer features intended for industrial operating conditions.
100% Oil-Free Air
For applications where clean air is important, an oil-free air delivery arrangement is highly desirable.
A1 Blowers’ Roots blower design separates the compression chamber from the lubricated bearing and gear sections, helping provide clean air at the discharge.
This makes the technology suitable for various water and wastewater treatment applications.
Low Noise and Vibration
Blower rooms can become uncomfortable when equipment generates excessive noise and vibration.
Properly designed Roots blower systems can help minimize operational noise and vibration, contributing to a better working environment and smoother plant operation.
Reliable Continuous Operation
WTP and wastewater-treatment facilities may need to operate for extended periods.
A robust blower construction helps provide dependable airflow during continuous operation when the system is correctly selected, installed, and maintained.
High Performance
Airflow and pressure requirements can vary from one treatment plant to another.
Selecting the correct blower based on operating conditions is essential for achieving the desired performance.
Long Service Life
A properly selected and maintained Roots blower can provide long-term service in industrial applications.
Regular inspection, lubrication of the appropriate components, correct alignment, and proper operating conditions can significantly contribute to equipment life.
How to Select the Right Roots Blower for a WTP
Selecting a blower should not be based only on the blower’s physical size or motor power.
A proper blower selection requires consideration of the actual operating requirements.
Airflow Requirement
The required airflow is one of the first parameters to determine.
It is generally expressed in units such as:
m³/hr
m³/min
CFM
The blower should be selected according to the actual airflow requirement of the treatment system.
Operating Pressure
The discharge pressure or pressure differential is equally important.
A blower must be capable of delivering the required airflow at the specified operating pressure.
Operating Hours
If the WTP operates continuously, the blower should be selected for the expected duty cycle.
Continuous-duty applications require appropriate equipment sizing and installation.
Installation Environment
The installation location can affect blower performance.
Temperature, ventilation, humidity, dust, and available space should all be considered during installation.
Motor Selection
Motor power should be matched to the blower operating point.
Oversizing or undersizing the motor can affect efficiency and operating costs.
Blower Configuration
Depending on the plant requirements, the system may require one or more operating blowers along with a standby unit.
A suitable configuration helps improve operational reliability and maintenance flexibility.
Applications of WTP Roots Blowers
Roots blowers can be used across multiple stages and systems associated with water and wastewater treatment.
Some common applications include:
1. Sewage Treatment Plant
2. Effluent Treatment Plant
3. Wastewater Treatment Plant
4. Water Treatment
5. Aquaculture/Fishing
6. Pneumatic Conveying
7. Electroplanting
8. Hatchery

Proper electrical connections
The suction and discharge piping should be designed according to the blower’s operating requirements.
Improper piping can increase pressure losses and place unnecessary load on the blower.
Roots Blower Maintenance for WTP
Regular maintenance helps improve blower reliability and service life.
A maintenance program may include:
Check Lubrication
Lubrication levels and condition should be inspected according to the manufacturer’s recommendations.
Inspect Belts and Coupling
Where applicable, belt tension and coupling alignment should be checked periodically.
Monitor Temperature
Unusual increases in bearing, gearbox, or discharge temperature should be investigated.
Check Vibration
Changes in vibration levels can indicate alignment, bearing, foundation, or other mechanical issues.
Inspect Air Filters
Dirty inlet filters can restrict airflow and increase blower load.
Check for Abnormal Noise
Any sudden or unusual noise should be investigated rather than ignored.
Preventive maintenance is generally more cost-effective than waiting for an unexpected equipment failure.
