"Availability or lack of availability of technologies for improving the energy efficiency of fans, blowers, and fume hoods": ******************* Response: * Fan system efficiency depends very much on a perfect combination of aerodynamics + transmission (belts) + motor + control system. --------------------- * ISO 12759 describes fan systems well and energy legislation is released in Europe with the ecodesign directive 2009/125/EC for product group lot 11 of directive 327/2011. --------------------- * Especially sections 7.0 (Improvement Potential; page 148) and section 7.5.2 (Trends in efficiency of fans and how they can further improved; page 156) of the linked document describes many innovations in the field of energy efficient fan systems. http://www.erp-richtlinie.at/fileadmin/eup/docs/Lot11_fans_final.pdf --------------------- regards/Armin Hauer
