Efficiency Comparison - PD Blowers vs. Turbo Blowers

Have you ever wondered where the Turbo Blower manufacturers obtained their data for their wild claims of 30-40% increase in efficiency over PD blowers? While pursuing a recent project we found that a turbo blower manufacturer (which we will keep unnamed) took the owner out to an existing WWTP plant in the area to compare the currently installed PD blower to their turbo machines.  The owner was amazed at how quiet and efficient the turbo blowers were and wanted his engineer to use them for their plant upgrades! What no one discussed that day, and what the turbo blower manufacturers hope no one discusses period, is that the PD blower packages used in the comparison were 20+ years old! Think about that for a moment. Technology makes leaps and bounds every 3-5 years, let alone 20! Existing technology is modified and improved upon constantly in a competitive market!

Today, PD blower systems are much more efficient than those installed in the past. There are multiple reasons why this is true, but the most significant reasons are as follows: improved blower efficiencies, improved motor efficiencies, direct driven systems. We will touch on each one of these in the attached paper.  There are even comparisons at the end for you to evaluate!

A Brief History Lesson - Universal Blower Pac

Universal Blower Pac was founded in May of 1979 by Ray Fiechter.  UBP was founded because there was a lack of customization regarding blower packages in the pneumatic conveying industry.  From his time working as a sales manager for a bare blower manufacturer, Ray noticed that the current manufacturers were limited in their ability to provide a customized solution to their clients.  In certain instances the manufacturer’s representative would package the equipment for their regional customers!   He felt that this gaping hole in the industry could be filled by an independent blower package manufacturer.  Thus UBP came into existence.

UBP manufactured packages primarily for the pneumatic conveying industry until 1985 when it entered the Water Treatment market.  Because Ray’s previous experience was in pneumatic conveying he wanted to establish the company and secure a place in that market prior to venturing into another market.  He knew there were plenty of opportunities in the water treatment industry and it wasn’t long before water treatment sales became a staple of the company.  Universal Blower Pac maintains a presence in the Pneumatic Conveying industry and also has experience building SVE (Soil Vapor Extraction) systems.  Shortly after entering the water treatment market, Universal Blower Pac was moved to its current location in 1986.  Due to the growth of the company the facility has expanded three times since the original building was erected!  1990, 1995, and 2009 were all years where the facility grew with the company.   The most recent expansion, which was completed earlier this year, is a topic in a previous post.

In 1988 UBP begins an alliance with Gardner Denver which had acquired the Sutorbilt and Duroflow PD blower lines in 1987.  What separates UBP from the rest of the blower packager manufacturers is our ability to customize our product and include any component requested by our clients.  This enables us to meet their needs to the fullest extent.  This ability also helps UBP adapt, as the industry and economy are always changing.  As an example, UBP has customers that are pressed for time and may not need customized products.  They only require a blower package that operates at their specified conditions.  Therefore UBP introduced the EXP package, or Express Package, in 1993.  This package can accommodate a range of flows and has a very short lead time when compared to other blower packages.

Fun Fact:  In the early 1980’s there were only two nationwide independent manufacturers of blower packages and the other company no longer manufactures blower packages.  Therefore, UBP is the oldest independent blower manufacturer that operates on a national level. 

The company has grown significantly with each passing year.  From time to time UBP has grown slower as the company adjusted its managerial and marketing methods to accommodate the market and economy changes.  Below is a timeline that highlights the significant events in the history of Universal Blower Pac.


We are currently working on future timeline worthy events such as the new product we will be unveiling in a few months!  An Energy Efficient Positive Displacement Blower System that remains efficient at multiple operating points or while turned down significantly!  More information on this system will be available in the coming months.  We also just secured our second best sales year in this unpredictable economy and have a chance to make it 4 straight record sales years!  Check back soon for more information on UBP.  There will also be a few “informational posts” that will help explain some of the technology we use and how it compares to other types of technology in the market

UBP Sound Attenuation


Universal Blower Pac has nearly 30 years experience engineering and producing acoustical enclosures for our customers. Noise regulations are much more prevalent than when we started and workplace safety has arisen as a key issue to private and public entities alike. Additionally, noise pollution has become a community concern and, in turn, its reduction a factor in the buying process of almost all customers.  Universal Blower Pac has addressed these concerns with continued testing and refinement of our custom sound enclosures built to meet your specific needs. We offer a wide variety of options available for almost any attenuation application.  Please view the technical paper prepared by a member of the UBP team.  This is only supplied as a PDF due to the size of the paper.  Please let us know if you have questions about the paper, we will gladly discuss it with you!

Positive Displacement (PD) Blower Basics

A technical post! Now we will provide some technical content to the blog.  A brief overview of how positive displacement blowers operate follows.

Positive displacement blowers do not generate pressure internally.  Instead, PD blowers overcome line pressure when they are in operation.  Air enters the inlet port of the blower and is trapped as the impeller rotates beyond the limits of the port opening.  There is no contact between the moving parts inside of the machine.  The air is trapped by the tight tolerances between the impeller and blower casing.  The air is moved around the impeller and blower casing to the opposite side of the blower towards the discharge port. Once the impeller chamber opens into the discharge port there is an equalization of pressure between the impeller chamber and the discharge line.  As the rotation continues, the air is forced out the blower and the process repeats.  The following illustration should help explain the process of how a PD blower overcomes line pressure.
Different applications require different blowers.  There are various types of blowers available and Universal Blower Pac selects the appropriate blower based on the needs of the facility.   We analyze the needs of the process or facility and package the right blower to maximize efficiency, lower noise, or reduce costs, whatever your prerogative may be!

Expanded Facility

We recently expanded our facility to accommodate our growing client base.  We have increased our storage capacity for stocking items and increased our package repair area.  What does this mean for you?  We can turn around new projects quicker than before and we can repair your existing blowers if you aren't in the market for a new one!  Also, some office space has been added to accommodate our growing sales and engineering teams.  Take a look at our new facility by clicking on the pictures below!
