Based on pressure output, the root blower market is segmented low (Upto 15 PSI), medium (15 PSI-30 PSI) and high (above 30 PSI). The low segment held around 52.6% of the market share in 2024.
 

• Low-pressure Roots blowers (up to 15 PSI operating pressure) are often used in municipal wastewater treatment, aquaculture and light industrial processes. Most often, low pressure Roots blowers are used because the application requires a continual, non-pulsating flow of air at low pressures.
   
• Most often used for aeration in biological treatment systems, low-pressure Roots blowers can also be used for other processes in which high pressure is not necessary, but where low pressure is critical or benefit, such as pneumatic conveying of powders or grains. Thus, the long-life and reliability position the low-pressure Roots blower as the preferred solution by public utilities for emergency response projects, as well as small to medium industrial projects.
   
• A major advantage of low-pressure Roots blowers is their energy efficiency. Low-pressure operation reduces energy consumption, an important factor for organizations looking to reduce costs and achieve their sustainability goals. Low pressure Roots blowers also have a simple mechanical construction with fewer moving parts, which simplifies maintenance and improves longevity. These can be easily installed with standard control systems, which is another advantage in retrofit and upgrading situations when convenience is a concern.
   

Based on the application, the root blower market is segmented into wastewater treatment, pneumatic conveying systems, cement production, chemical processing, power generation and other. In 2024, wastewater treatment held a major market share, generating a revenue of USD 204.3 million.
 

• Root blowers are essential for wastewater treatment operations, especially in aeration processes in biological treatment systems. Roots blowers provide a steady flow of air to allow aerobic bacteria to grow in the wastewater for the purpose of digesting the organic waste in the wastewater. These low-pressure Roots blowers generate continuous, oil-free air flow to increase oxygen transfer rates which improves operating efficiency and process stability for activated sludge processes. Additionally, Roots blowers perform effectively and consistently under variable loads, which is why they are preferred in municipal and industrial treatment facilities.
   
• These are a critical end-use market for the wastewater treatment sector because aeration is key to proper biological treatment processes. They are designed to provide a continuous flow of air to a treatment plant's aeration tanks to promote the growth of aerobic bacteria that breaks down organic waste in wastewater. They are often used due to their ability to provide a continuous flow of steady, oil-free, and pulsation-free air, which teaches proper oxygen levels for effective biological treatment. They are also used for backwashing filters and agitating sludge, while the liquid continues to flow through the treatment plant uninterrupted.
   
• As more global focus on environmentally sustainable development grows combined with more stringent requirements for wastewater discharge, inclusive of high-level performance and reliability, the need for aeration systems has grown. These two issues are positively impacting the root blower market, especially in regions that are investing heavily into removing wastewater infrastructure, as technology improves in design and function to better the wastewater treatment processes, i.e. producing a blower that consumes less energy while producing lower noise levels. Municipalities and industries are looking for ways to do more with less investment while meeting environmental specs which evidently identifies the key role of root blowers in complementing innovations in modern wastewater treatment.
