🔍 Key Concepts

• Roots-type blower design and how air moves through it • Difference between positive displacement devices and dynamic (non-positive displacement) compressors • Common examples of centrifugal and axial flow compressors

💭 Think About

• Think about whether a Roots blower traps fixed pockets of air and moves them, or whether it accelerates air with high velocity and then slows it down to raise pressure. • Compare how a rotary vane pump works versus how a Roots blower’s lobes rotate and interact with the casing. • Ask yourself which types of compressors (axial, centrifugal, or positive displacement) are normally used for high-volume, low-pressure versus steady, fixed-volume delivery per revolution.

✅ Before You Answer

• Verify whether a Roots blower delivers a nearly fixed volume of air per revolution regardless of discharge pressure (within limits). • Confirm that axial flow and centrifugal machines are usually classified as dynamic, not positive displacement. • Check drawings or descriptions showing whether the blower has two intermeshing lobes that carry air from inlet to outlet in sealed spaces.
