By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

Industrial air guns are essential for cleaning manufacturing equipment and production areas, but improper selection or misuse can create serious safety and compliance risks. This article explains OSHA Standard 1910.242(b), the engineering behind OSHA-compliant safety air guns, and how nozzle design, thrust, noise control, and operator training help facilities improve worker safety while maintaining effective industrial cleaning performance.

Engineering Sales Associates Maintains Production with Preventive Maintenance

By Arthur Pue, President, Engineering Sales Associates 

Preventive maintenance is seldom newsworthy inside manufacturing facilities. By design, preventive maintenance should be a non-event. Production keeps running, shifts continue to change, trucks are reloaded and unloaded and work goes on. The reliability of a compressed air system requires focus, attention and discipline: paying attention to variables, detecting patterns and knowing when something seems amiss. Looking deeper into system performance turns routine maintenance into a strategic tool for improving reliability and production stability.

Advanced Compressor Technologies Solves Oversupply Problem

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine 

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.

High-Altitude Mining and Steel Production in Peru

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

Before CAGI data sheets were created, air compressor distributors and their customers could only go by the manufacturers’ claims. He found there wasn’t any uniformity to the numbers manufacturers put out, so making comparisons was challenging. Some compressed air manufacturers measured capacity from the bare airend, while others measured from the air compressor’s outlet.
