Pollution Engineering - October 2008 - (Page 41) Taking the PRESSURE off By JAY JARBOE, Sales Manager, Ametek Technical and Industrial Products y , g Blower Selection Regenerative blowers are finding their niche in many pressureblower applications. Energy efficiency, low maintenance and reduced pollution are several reasons why. B lowers provide critical aeration for proper biological oxygen demand in water treatment applications. But changes are in the wind concerning the equipment used to perform these jobs, largely due to mounting industry pressures to reduce energy and maintenance costs, simplify processes, and improve reliability. Most blower applications can be satisfied by multi-stage or positive-air-displacement blowers and compressors, but at a relatively high price when factoring in their levels of energy consumption and maintenance requirements. In contrast, regenerative-blower technology can serve as a practical, efficient and industry-friendly alternative to help keep costs down and output high. How does it work? Regenerative blowers draw air or other gases into the blower unit by impeller blades passing an inlet port. The blades then accelerate the air in an outward and forward direction using centrifugal force. The air is turned back, or regenerated, by the blower’s annular-shaped housing to the base of followOCTOBER2008 www.pollutionengineering.com 41 http://www.pollutionengineering.com
