The HVAC equipment industry is not known for rapid change. Although control systems have improved rapidly over the past few years, fans are still much the same as they were 20 years ago. Accessories such as air diffusers and vibration isolators have gone through small, incremental changes in the same time period. In the past 12 months, several new products have caught the author's attention. These represent significant improvements in noise control and/or design flexibility and installation quality. This presentation will include product information on these new products along with a discussion of their pertinent advantages. Industry trends such as wider availability of sound data and custom engineered air handling units will also be discussed.
