Roots Blower – The Original Positive Displacement Blower
What is a Positive Displacement Blower?
A positive displacement blower is designed to deliver a consistent air volume with each rotation, regardless of changes in discharge pressure. This characteristic makes it indispensable for applications requiring a reliable airflow under variable pressure conditions, ensuring steady, efficient performance across industries.
Advantages of Roots Positive Displacement Blowers
Consistent Airflow
Roots blowers provide a set volume of air per rotation, making them ideal for applications where steady airflow is crucial, such as pneumatic conveying.
High Reliability and Durability
Roots blowers are renowned for their robust design and resilience in harsh environments. Their construction ensures that they continue to operate effectively with minimal maintenance, reducing downtime and operating costs.
Adaptable Pressure Range
With pressure ratings up to 18 PSI and vacuum capabilities down to 27"HgV, Roots blowers are highly versatile for a wide range of industrial uses.
Compact and Efficient
Roots blowers often have a compact footprint, allowing for easy integration into existing systems, especially when space is limited. This also aids in simpler installation and maintenance, further enhancing their value.
Availability and Support
Positive displacement blowers, including the renowned Roots blowers, are readily available from suppliers, often in stock for prompt shipment. These suppliers provide a comprehensive range of services, including parts, maintenance, and custom solutions tailored to your needs.

ROOTS RCS Rotary Positive Blowers
Designed for robust industrial use, the RCS series offers reliable performance with superior materials and precision engineering, meeting the needs of high-demand environments.
Why Choose a Roots Blower Over Fans or Compressors?
Compared to fans and compressors, positive displacement blowers like Roots blowers offer medium pressure with exceptional durability and reliability. These units excel in industrial applications that require constant airflow without interruptions due to pressure fluctuations. This dependable performance ensures process consistency and superior product quality.
