dresser roots blower

A Dresser Roots blower is a type of positive displacement blower, specifically a rotary lobe blower, used for moving air or gas. It’s known for its ability to provide a consistent airflow, even under varying pressure conditions, making it suitable for a wide range of industrial applications. Dresser, formerly a company, now a brand, is known for its Roots blowers, which are widely used in various industries like water treatment, wastewater treatment, and pneumatic conveying.

Key features and characteristics of Dresser Roots blowers:

Positive Displacement:

Roots blowers trap a fixed volume of air or gas and move it against pressure.
Rotary Lobe Design:

They utilize two rotating lobes (or impellers) within a casing to move the fluid.
Consistent Airflow:

Roots blowers are known for delivering a steady flow of air, making them reliable for processes requiring a consistent supply.
Industrial Applications:

They are used in diverse sectors like water and wastewater treatment, pneumatic conveying, and various industrial processes requiring air or gas movement.
Dresser Brand:

Dresser Industries was a company that acquired the Roots blower brand, which is now part of Ingersoll Rand.

How it works:

The blower’s rotors, often called lobes, rotate in opposite directions within a casing. As they rotate, they trap a volume of air and carry it from the inlet to the outlet, creating a flow of air or gas. The pressure at the outlet is determined by the resistance of the system it’s connected to.
