What is a Root Blower? A root blower , also known as a roots type blower or positive displacement blower , is a mechanical device designed to move a fixed volume of air or gas from in let to outlet. Unlike centrifugal blowers, a root blower provides constant airflow regardless o...

In modern industrial processes, Positive Displacement Blowers (PD Blowers) play a vital role wherever consistent airflow at controlled pressure is required. From wastewater treatment to pneumatic conveying, PD blowers are trusted for their reliability, efficiency, and rugged design. At SWAM , we manufacture high-performance Rotary PD Blowers engineered to deliver dependable airflow solutions across industries. This blog explains what positive displacement blowers are, their working principle, major types like tri lobe rotary piston and twin lobe blower , and their key applications. What Are Positive Displacement Blowers? Positive displacement blowers are mechanical devices that move a fixed volume of air or gas per revolution, regardless of pressure changes. Unlike centrifugal blowers, PD blowers maintain a nearly constant flow rate even when system pressure fluctuates. Key Characteristics of Positive Displacement Blowers: Constant airflow at varying pressures High efficie...
