Positive Displacement Blower: Types, Working Principle, Applications, and Choosing the Right Manufacturer
A positive displacement blower is one of the most reliable and widely used air-moving solutions across industries that require consistent airflow, controlled pressure, and durability. From wastewater treatment plants to pneumatic conveying systems, this equipment plays a critical role in maintaining operational efficiency.
Unlike dynamic blowers that rely on velocity to create pressure, a positive displacement air blower works by trapping a fixed volume of air and forcing it through the system. This simple yet powerful principle makes it highly dependable in demanding industrial environments.
In this in-depth guide, we’ll break down everything you need to know—how a positive displacement blower works, the different types available, real-world applications, advantages over alternatives, and what to look for when choosing among positive displacement blower manufacturers like akash blowers.
What Is a Positive Displacement Blower?
A positive displacement blower is a mechanical device that moves air or gas by repeatedly enclosing a fixed amount and transporting it from the inlet to the outlet. The airflow remains nearly constant regardless of pressure changes, making it ideal for processes that require stable performance.
Key Characteristics
- Delivers constant airflow
- Operates efficiently under varying pressure
- Handles clean air and gases
- Long service life with proper maintenance
Industries choose positive displacement blowers when process stability is more important than variable flow control.
Positive Displacement Blower Working Principle Explained
Understanding the positive displacement blower working principle helps users select the right equipment and operate it efficiently.
Step-by-Step Working Mechanism
Air enters the blower through the inlet port
Rotating elements (lobes, screws, or vanes) trap a fixed volume of air
The trapped air is carried from inlet to outlet
Air is discharged at higher pressure into the system
The critical point is that air is not compressed internally. Pressure builds only when airflow meets system resistance.
Why This Matters
Consistent flow regardless of pressure
Predictable performance
Better control in industrial processes
Types of Positive Displacement Blowers
There are several positive displacement blower types, each designed for specific operational needs. Choosing the right type depends on pressure requirements, airflow volume, noise limits, and energy efficiency.

Roots Blowers (Classic PD Blowers)
Roots blowers are a traditional form of positive displacement rotary lobe blowers, known for their rugged performance.
Key Characteristics
- Two-lobe or three-lobe design
- Constant air delivery
- Minimal internal wear
Typical Uses
- Mining
- Steel plants
- Bulk material handling
- Environmental engineering
