Industrial Utility Efficiency

Air Compressors

From October 29-31, 2024, professionals who operate, maintain and design industrial compressed air, vacuum, blower, nitrogen generation, process cooling and HVAC systems gathered at the Cobb Galleria Centre in Atlanta, GA, for the 6th annual Best Practices 2024 EXPO & Conference. The event featured two tracks of conference presentations and panels.

2026 Compressed Air Distributor Sales Survey

Compressed Air Best Practices® Magazine has conducted its first-ever reader survey for this 20th anniversary issue, and the results show a positive outlook for compressed air system sales in the near future. 

The CABP Interview: FS-Elliott CEO Everson De Campos on Centrifugal Air Compressor Engineering

In this interview, FS-Elliott CEO Everson De Campos discusses the company’s strategic direction, emphasizing innovation, sustainability and advanced manufacturing in centrifugal air compressor technology. He highlights investments in global production, engineered-to-order solutions and new product development, including the Polaris platform, as well as growing demand for oil-free compressed air in critical industries. The conversation also explores lifecycle service innovations, digital monitoring approaches and the importance of workforce and channel partner training in meeting increasingly complex customer requirements.

Variable-Speed Rotary Screw Air Compressors, Food-Grade Oil Selection and System Audits for Food Processing Facilities

Through detailed plant audits, load profiling and system standardization, a regional distributor helped a multi-plant food processor optimize its compressed air infrastructure using 200 hp lubricated VSD rotary screw compressors, 10,000 gallons of storage and properly specified food-grade lubricants. By focusing on correct sizing, temperature monitoring, contamination prevention and lifecycle maintenance practices in dusty environments, the installations delivered stable operating pressures, improved energy performance and scalable capacity for continued expansion.

Rotary Screw Booster Advances for Blow Molding

Compressed air boosters are engineered to amplify medium-pressure air (90–150 psig) to high-pressure ranges up to 435 psig (30 barg) using oil-free rotary screw technology, IE5 permanent magnet motors and advanced VSD+ drivetrains for improved turndown and energy efficiency. By combining Class 0 oil-free air quality, synchronous PM motor performance (up to 97% efficiency) and intelligent controls, next-generation booster systems deliver higher flow stability, reduced specific energy consumption and seamless integration into existing compressed air networks.

Demystifying the Myths of Centrifugal Air Compressors

Centrifugal air compressors are widely used in industrial compressed air systems, yet misconceptions remain regarding capacity control, surge behavior, and operational complexity. This article provides a technical overview of modern centrifugal compressor design, explaining how inlet guide vanes, bypass controls, and microprocessor-based algorithms enable efficient operation across varying demand while mitigating surge. It clarifies proper application and sizing considerations to help engineers and plant operators make informed equipment decisions.

Advanced Compressor Technologies Solves Oversupply Problem

A Southern Indiana office furniture plant was wasting hundreds of dollars per day because its oversized VSD air compressor could not turn down low enough to match reduced demand after a shift to metal fabrication. To avoid drive faults, the plant vented compressed air to create false load. The audit revealed 300 cfm of wasted air—about $400 per day—and led to a redesigned system using a fixed-speed compressor for base load and a VSD unit for trim. The new configuration eliminated artificial demand and cut compressed air energy use in half, setting the stage for further savings through advanced sequencing, storage, and demand control.

Lubricant Analysis Improves Air Compressor Reliability

Effective lubricant analysis delivers substantial and proven ROI measured in increased productivity, oil drain intervals and equipment life. With disciplined deployment and technical oversight, lubricant analysis transforms maintenance from reactive to predictive, aligning with industry best practices and RCM principles.

Egger Modernizes Its Compressed Air System for the ESG Era

Wood-based materials manufacturing plant transformed its compressed air system from an invisible utility into a data-driven energy asset by deploying a modern, multi-zone monitoring and control platform. The upgrade delivered real-time transparency, ISO 50001- and ESG-ready reporting, and verified annual savings of 1.43 GWh, \$166,500 and 889 tons of CO2.

Best Practices 2025 EXPO & Conference Show Report

The Best Practices 2025 EXPO & Conference was the busiest one yet, with 89 presentations, 84 exhibitors and nearly 1,000 registered attendees. It included two conference tracks, five workshops and five EXPO classroom pavilions. The event was so big, we’re splitting our show report into three reports to capture all the activity. 

The Business Case for Air Compressor Rentals and Air-Over-the-Fence

There is no single right approach to putting the necessary volume and pressure of air in the pipe to meet production needs. There is a place for purchasing assets, there is a place for renting assets and there is a place for an AOF contract. Just as the business models around these assets change, so do the needs of an industrial plant. This article aims to explore these options and explore some of the pros and cons associated with different methods.
