Howden Roots Positive Displacement Blowers

Howden Roots positive displacement blowers, often simply called Roots blowers, are a type of rotary lobe pump used for moving air or gas in various industrial and wastewater treatment applications. They are known for their durability, reliability, and suitability for medium-pressure applications. Howden continues to manufacture these blowers at the original factory in Connersville, Indiana, USA.

Key Features and Characteristics:

Positive Displacement:
Roots blowers operate by trapping a fixed volume of air or gas between rotating lobes (resembling stretched gears) and physically pushing it out, rather than relying on centrifugal force like fans.
Durability and Reliability:
They are known for their rugged construction and ability to handle demanding industrial conditions, often with features like heavy-duty cast iron casings and alloy steel timing gears.
Versatility:
Roots blowers are available in various sizes and can be customized for specific applications, including different pressure and vacuum requirements.
Medium Pressure Applications:
They are particularly well-suited for applications where moderate pressure increases are needed, offering a good balance of performance and efficiency.
Applications:
Common uses include wastewater treatment (aeration), pneumatic conveying, and various industrial processes where a reliable source of pressurized air or gas is required.
Howden Roots Specifics:
Howden continues to manufacture the original Roots blowers from the Connersville factory, and their product line includes models like the URAI, RAM, and RCS series, each designed for specific applications and performance characteristics.
