Positive Displacement Blowers
Positive displacement blowers are mechanical devices used to move air or gas by trapping a fixed volume of fluid and forcing it through the discharge outlet. They are commonly employed in various industrial applications, such as wastewater treatment, pneumatic conveying, and aeration systems. Here’s a detailed overview of positive displacement blowers, including their features, advantages, applications, and maintenance considerations.
- Features of Positive Displacement Blowers
Fixed Volume Displacement: These blowers operate by mechanically trapping a specific volume of air or gas and moving it to the discharge outlet, ensuring a consistent airflow.
Variety of Designs: Common types of positive displacement blowers include rotary lobe blowers, rotary screw blowers, and diaphragm blowers, each with unique operational principles.
Variable Speed Options: Some models are equipped with variable speed drives (VSDs) to allow for precise control of airflow according to demand.
Low Pulsation: They typically provide a steady and smooth airflow with minimal pulsation, which is beneficial in sensitive applications.
- Advantages of Positive Displacement Blowers
High Efficiency: They offer high efficiency, particularly in applications requiring consistent airflow at lower pressures.
Durability: Designed for robust performance, these blowers have fewer moving parts than some other types of blowers, leading to longer operational lifespans.
Wide Range of Applications: Positive displacement blowers can handle a variety of gases, making them versatile for different industrial needs.
Simple Maintenance: With fewer components that can wear out, these blowers are often easier and less expensive to maintain.
- Applications of Positive Displacement Blowers
Wastewater Treatment: Commonly used for aeration in biological treatment processes to maintain oxygen levels for microbial activity.
Pneumatic Conveying: Employed in conveying bulk materials such as powders, grains, and pellets in various manufacturing and processing applications.
Aquaculture: Used to aerate water in fish farming and aquaculture systems, ensuring a healthy environment for aquatic life.
Food and Beverage Industry: Utilized for packaging, conveying, and aeration processes in food and beverage production.
- Maintenance Considerations
Regular Inspections: Routine inspections are necessary to check for wear, leaks, and overall performance.
Lubrication: Ensure proper lubrication of moving parts according to the manufacturer’s specifications to minimize friction and wear.
Filter Maintenance: Keep intake filters clean and replace them as needed to prevent contaminants from entering the blower.
Monitoring Performance: Utilize performance monitoring tools to track metrics like pressure and airflow to identify any inefficiencies.
- Selection Criteria
Flow Rate and Pressure Requirements: Assess the specific flow and pressure needs of your application to select the appropriate blower model.
Energy Efficiency: Look for blowers with high efficiency ratings to reduce operational costs and energy consumption.
Construction Material: Consider the materials used in the blower’s construction, especially for applications involving corrosive gases or harsh environments.
Noise Level: Evaluate the noise level of the blower, particularly if it will be used in noise-sensitive environments.
Conclusion
Positive displacement blowers are reliable and efficient solutions for a wide range of industrial applications requiring consistent airflow and pressure. Their robust design, high efficiency, and versatility make them a valuable asset in industries such as wastewater treatment, food processing, and pneumatic conveying. When selecting a positive displacement blower, it is essential to consider the specific needs of your application to ensure optimal performance and efficiency.

AERZEN offers a wide range of products in the field of compression technology, possibly the widest that you will find anywhere. The highly-developed machines are available in a wide range of designs, sizes and special models; for conveying air, oxygen, neutral, aggressive or toxic gases; with vertical or horizontal flow; in negative pressure, positive pressure or vacuum modes. They can be used anywhere in the world where gas needs to be conveyed and compressed, and anywhere where reliable availability, energy efficiency and oilfree supply are the decisive factors.
They are tried and tested – and more innovative than ever.
AERZEN made Europe’s first positive displacement blower. That was in 1868. Today these stages and packaged units are numbered among the most successful compressors of all time. We manufacture highly-developed standard products for the most diverse range of applications that are used in all branches of industry. Our machines are high-performance, economical and extremely durable.
The roots design paved the way for the development of the AERZEN positive displacement blowers, and it is a good thing that it did. Even now, 150 years later, it is still one of our most successful construction designs. Today AERZEN twin-shaft positive displacement blowers for oil-free conveyance are more innovative than ever. The many developments in construction ensure first-class values when it comes to efficiency. AERZEN patented technology such as the integrated pulsation reduction ensure low noise emissions and vibrations. Also typical for AERZEN blowers is the ease of servicing and long term reduction in life-cycle costs. And the list of innovative details goes on and on. But what matters most in practical
everyday terms? The lasting quality of our blowers. That is what Made in AERZEN is known for.
