Blower & Vacuum Best Practices — Industrial Utility Efficiency

As the Best Practices Magazines celebrate their twentieth anniversary, we wanted to take a moment to reflect on the remarkable system efficiency gains achieved since our first issue. We also wanted to give subscribers a peek at what the next decades might bring. To do this, we asked a hand-selected list of original equipment manufacturers, independent compressed air system sales and service companies, manufacturing plants and independent system auditors to share their thoughts, highlighting the changes they’ve seen over the past 20 years, then predicting what the next 20 years will bring.

This article examines how industrial facilities can quantify the return on investment associated with disciplined filter change scheduling. By connecting pressure drop, energy consumption, maintenance costs and equipment longevity, facilities can move from reactive maintenance to measurable operational control.

In 2019, the City of East Peoria, IL, began a comprehensive modernization of its wastewater infrastructure, including a $68 million upgrade covering two operating facilities, Wastewater Treatment Plant No. 1 and Wastewater Treatment Plant No. 3. The project addressed aging equipment, regulatory pressure and the need for improved process control.

By replacing liquid ring and compressed air systems with centralized rotary claw vacuum pumps, Austrian pasta manufacturer Wolf Nudeln significantly reduced water consumption, maintenance requirements and operating costs. This case study demonstrates how modern vacuum technology improves efficiency, reliability and product quality in food manufacturing while supporting long-term sustainability goals.

Learn the key differences between positive displacement (PD) and centrifugal blowers and how advances in blower technology, variable-speed controls and lifecycle cost analysis are reshaping equipment selection. This article explains blower operating principles, performance characteristics and application considerations to help engineers optimize energy efficiency, reliability and long-term operating costs in wastewater, industrial and process air systems.
