Blower Standards

Blower & Vacuum Best Practices® Magazine interviewed Ms. Julie Gass P.E., Lead Process Mechanical Engineer, from Black & Veatch on trends in the wastewater treatment industry especially pertaining to new technology aeration blowers and energy efficiency.
Hoffman & Lamson has been manufacturing multi-stage centrifugal blowers for a long time. Lamson was founded in 1880, and Hoffman was established in 1905. Now a single entity under the Gardner Denver Nash Division, the company has some serious resources to complement its 100-plus years of blower expertise.
Industrial standards provide a common means of understanding and communicating performance. This article examines the rationale and applications of the Compressed Air & Gas Institute’s standards for determining the energy efficiency of low-pressure blower packages.
In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove.
Most readers of this magazine are familiar with the ISO 9000 and 14000 families of standards.  The 9000 family pertains to quality management systems and the 14000 family deals with environmental management.
