The DB-M dust suppressor.
The DB-M is designed for operating conditions involving very fine dust particles, including slag dust or fly ash. The unit generates an umbrella-shaped cloud of atomized droplets averaging 50-200 microns in size, projecting the mist about 30 feet (9.14 m) under calm conditions. The new design features selectable flow settings and proprietary Variable Particle Sizing (VPS) Technology to improve capture efficiency. Nozzles can be added, removed or re-sized as the application dictates. Just 10 PSI of water pressure is required from the supply hose when using the integrated booster pump, giving the DB-M an output as high as 24 GPM at 200 PSI. An in-line 30 mesh filter stops any solids 600 microns and larger, and the manufacturer recommends that it be used at all times. If using potable water, nozzles can be inspected just once a year.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
