In late October 2023, professionals from around the world gathered at the Best Practices 2023 EXPO & Conference at McCormick Place in Chicago, Illinois to source and learn about Sustainable, Safe and Reliable On-Site Utilities Powering Automation including compressed air, blowers, vacuum, pneumatics, motors and cooling water systems. 

Blowing a jet of compressed air at an object is a common but “poor” use of compressed air. Often the blowing nozzle is a piece of pipe on a hose with a manual valve for control. This quickly solves a production problem when a more efficient factory made nozzle is either physically too big, too expensive, or not on site when needed. Retrofitting with factory made nozzles is often ruled out by for the same reasons, and the time needed by managers and fitters to change a nozzle for often little gain in production.

Weftec 2023, a leading event for industrial and municipal wastewater treatment facilities took place October 2-5, 2023 at Chicago's McCormick Place. The objective of this article is to provide readers with a sampling of aeration blower technologies on display at the show. We regret not being able to include all exhibitors or visits made due to article length considerations. 

If your vacuum pump is malfunctioning, you are faced with a choice: repair or replacement. Our guide will take you through both options and provide recommendations on when it makes sense to repair vacuum pumps and when to replace them. We will also take a look at how to spot and diagnose common issues before they lead to system failure.
Whatever the path of action, the decision to repair or replace always begins with testing and diagnosis. A factory-trained service technician who specializes in vacuum pump services inspects the equipment and identifies the problem.
