blower & vacuum
Blowers and vacuums are essential tools in various industrial and commercial applications, serving different purposes in air movement and fluid handling. Here’s a detailed overview of both blowers and vacuums, including their features, types, applications, and maintenance considerations.
Blowers
Definition: Blowers are devices designed to move air or gases by generating a flow of air. They are often used to supply, exhaust, or recirculate air in various applications.
- Types of Blowers
Positive Displacement Blowers: These blowers trap a specific volume of air and move it through the discharge. Common examples include rotary lobe blowers and screw blowers.
Centrifugal Blowers: These blowers use a rotating impeller to increase the velocity of the air, which is then converted into pressure. They are often used for high flow rates.
Regenerative Blowers: These utilize a rotating impeller that increases air pressure by repeatedly passing it through a series of blades, providing a compact design with moderate pressure capabilities.
- Applications of Blowers
Wastewater Treatment: Used for aeration in treatment tanks to maintain necessary oxygen levels for microbial activity.
Pneumatic Conveying: Employed to transport bulk materials like powders and grains in manufacturing and processing industries.
HVAC Systems: Used for ventilation and air circulation in heating, ventilation, and air conditioning systems.
Aquaculture: Used to aerate water in fish farms, ensuring a healthy environment for aquatic life.
- Maintenance Considerations for Blowers
Regular Inspections: Routine checks for wear, leaks, and overall performance are essential.
Lubrication: Follow the manufacturer’s specifications for lubricating moving parts.
Air Filter Maintenance: Keep intake filters clean to prevent contaminants from entering the blower.
Performance Monitoring: Utilize tools to track pressure and airflow metrics for efficiency.
Vacuums
Definition: Vacuums are devices that create a negative pressure to suck air or other substances, often used for cleaning, material handling, or extracting dust and debris.
- Types of Vacuums
Industrial Vacuums: Designed for heavy-duty applications, capable of handling large volumes of dust, debris, or liquids. Examples include wet/dry vacuums and portable industrial vacuums.
Centralized Vacuum Systems: Permanent installations in buildings that use a network of pipes to transport debris to a central collection point.
HVAC Vacuums: Used specifically to remove debris and contaminants from HVAC systems during maintenance or installation.
- Applications of Vacuums
Cleaning: Used in industrial settings for cleaning floors, machinery, and work surfaces.
Material Handling: Employed to transport bulk materials, such as powders and granules, in manufacturing processes.
Laboratory and Medical Uses: Used to create a vacuum in laboratory equipment or for suction in medical applications.
HVAC Maintenance: Utilized to remove dirt and debris from ductwork and other components.
- Maintenance Considerations for Vacuums
Filter Cleaning or Replacement: Regularly clean or replace filters to maintain suction power and efficiency.
Inspect Hoses and Attachments: Check for wear or damage that could affect performance.
Monitor Performance: Regularly evaluate vacuum performance to ensure optimal operation.
Motor Maintenance: Follow manufacturer guidelines for motor care to prevent overheating and extend the vacuum’s lifespan.
Conclusion
Blowers and vacuums play critical roles in various industrial and commercial applications. Blowers are primarily used to move air or gases, while vacuums create negative pressure to suck in air or materials. Understanding the different types, applications, and maintenance needs of each can help ensure optimal performance and efficiency in their respective uses. When selecting a blower or vacuum, consider the specific requirements of your application to choose the right equipment.

I had a very interesting meeting with Julie Gass and Patrick Dunlap, this summer at Black & Veatch’s offices in Kansas City. In a fascinating conversation, we reviewed a host of technologies ranging from panel diffusers to aeration blowers. Somewhere in the middle we did a long, challenging, review of DO Control, Most Open Valve Control, Flow Control and even Ammonia Control strategies. Leading off this Issue, we hope you learn as much as I did and enjoy “Part 1: The Demand Side – Diffusers and DO Control”.
The wastewater treatment plant in the Town of Hurlock, Maryland provides service to approximately 2,100 residences. However, the majority of the water treated comes from a nearby poultry processing plant, giving the plant influent a high organic content. That is why the Town
of Hurlock replaced its two million-gallon-per-day (MGD) lagoon plant with a 1.65 MGD four- stage activated sludge facility ten years ago. Paul Petersen, from Atlas Copco, shares this story with us about how they reconfigured their aeration blowers to reduce energy consumption.
Tim Hilgart, from Howden Roots, writes about how their DO Control system was able to optimize the 180 MGD challenge at the Bird Island wastewater treatment plant in Buffalo, N.Y.. This article demonstrates expertise in Most Open Valve Control logic, an expertise for which there is growing demand. The project delivered an annual savings of 3.8 million kWh equaling
$345,000 with an excellent ROI assisted by a NYSERDA rebate covering fifty percent of the cost.
Tom Jenkins is the President of JenTech and is an expert consultant on aeration blowers. He also explains things in a way I can understand! For those of you in the field, he has provided a very useful article (one for the files) with the steps to calculate the air flow rate, how
to determine the best strategy for blower turndown, and the calculations to establish the required discharge pressure.
Last but not least, I hope you enjoy our Show Report on blower and vacuum technologies at AISTech 2016. Steel degassing processes are switching to mechanical vacuum systems, providing up to 97% energy reductions according to Edwards and Oerlikon Leybold booth personnel. Blow-off air processes are also being optimized with dedicated blower and custom air knife technologies and we enjoyed visiting with Sonic Air Systems and Silvent InTech. Our technologies really are helping the steel industry be more efficient.

CAGI Blower Section Announces
New BL300 Blower Data Sheets
The Compressed Air and Gas Institute’s (CAGI) Blower Section has announced plans to make Blower Package Data Sheets available in the near future. The sheets are based on testing conducted according to the CAGI/PNEUROP
BL 300 standard, Performance Test Code for Electric Driven Low Pressure Air Compressor Packages. BL300 is a new joint standard developed through cooperative work by US
and European trade associations. The CAGI/ PNEUROP standard is designed to enable the collection and presentation of comprehensive and consistent performance data independent of blower technology.
In addition to the BL300 document, CAGI has established a standard means for manufacturers to report their machines’ performance and efficiency in the form of data sheets. Blower Section Chair, John Conover, said “Members have committed to publishing data sheets for 75 hp, 100 hp, and 150 hp models in the second half of 2016.”
Committee Chair
The data sheets will cover fixed and variable speed drive units for both positive displacement and dynamic blower technologies. These
data sheets will be accessible via a link on the CAGI website under the “Performance Verification” tab.
The joint standard enables the fair comparison of package performance on a level playing
field. “BL 300 is a standard means of evaluating blowers which provides users with complete package performance data that was just not available before,” according to Chris Johnson, Executive Director of CAGI. “It includes a reference to ISO 1217, the standard for testing positive displacement blowers, and to BL 5389, the standard for testing turbo blowers.”
The development of BL 300 was initiated at the request of the wastewater treatment industry; however, the standard was expanded to make
it suitable for use with blowers in general industry and other applications. When blower packages are compared using BL 300 results, plant managers, engineers, and technical advisors can use CAGI datasheets to access the following performance information:
