Trusted Roots Blower Solutions for Industrial Applications


Proven Technology and Reliability

■ Legacy of Innovation: Original pioneer of the Roots Blower, established in 1854

■ Unmatched Reliability: Guaranteed durability and dependability with over 170 years of proven expertise

Roots Blower – The Industry Standard in Positive Displacement

What is a Positive Displacement Blower?

 Positive Displacement (PD) blowers are engineered to deliver a constant volume of air per revolution, regardless of changes in discharge pressure. This characteristic is essential for various industrial processes that require stable airflow under fluctuating pressure conditions, ensuring consistent and efficient performance. 

Features and Benefits

Compact Design and Easy Installation

■ Space-Efficient : Small footprint allows for seamless integration into existing systems

■ Flexibility : Available as a Bare shaft unit or a Complete Package Configuration

Low Operating Costs via Robust Design

■ Industrial Strength : Cast-iron construction and heavy-duty bearings ensure continuous operation

■ Simplified Maintenance : Designed with a simple structure for easy servicing

■ Cost-Efficiency : Minimal consumables lead to significantly lower operating costs

Consistent Airflow and Versatile Applications

■ Consistent Performance : Positive displacement technology provides constant airflow regardless of pressure fluctuations

■ Wide Application Range : Ideal for wastewater treatment, pneumatic conveying, combustion, and vacuum systems

■ Multi-Gas Compatibility : Capable of handling various gases, from steam to nitrogen and hydrogen

■ Steel Degassing : High-performance vacuum boosting for specialized industrial processes

High Efficiency & Low Noise with WHISPAIR™

■ Reduced Pulsation : Achieves up to 40% pulsation reduction for lower noise and vibration

■ Enhanced Stability : Improves mechanical durability through low-load and low-vibration design

■ Optimized Power : Boosts energy efficiency by supporting impeller motion and reducing power loss
