High SpeedHigh speed fans deliver more air but are louder than low speed fans of the same size. They are more suitable in applications where maximizing airflow is the primary objective and a louder noise level is tolerable.ApplicationsNote that unlike 115V fans, 230V fans cannot be powered directly by an US outlet. This model is used to replace fans in industrial equipment running at 220-240V such as ovens and washing machines; and also products from Europe.PDF Specification Sheethttp://www.acfdserver.com/products/FA1225B22T9-96/2012-2013%20COOLTRON%20E-Catalog_133.pdf Other AC Infinity products to consider (Airflow CFM, Noise dBA): Copy and paste links to view115V AC Cooling Fan 120mm x 25mm High Speed (68 CFM, 39 dBA): http://www.amazon.com/gp/product/B004YZ5B9C230V AC Cooling Fan 120mm x 38mm Low Speed (80 CFM, 39 dBA): http://www.amazon.com/gp/product/B0071HDDY0230V AC Cooling Fan 92mm x 25mm High Speed (34 CFM, 35 dBA): http://www.amazon.com/gp/product/B007OOOK88
