If several fans are used in parallel, e.g. in a FanGrid (fan wall), this problem can be exac\u00ader\u00adbated by inter\u00adac\u00adtions between the fan and the design prop\u00ader\u00adties of the system. In addi\u00adtion, fan vibra\u00adtion char\u00adac\u00adter\u00adis\u00adtics usually change when the fans are installed in the customer\u2019s device. An addi\u00adtional imbal\u00adance caused, for example, by damage during trans\u00adport or handling can also have a nega\u00adtive impact on the service life and lead to the fan falling short of its usual 40,000 oper\u00adating hours.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Crit\u00adical speed ranges \u201coverrun\u201d<\/h2>\n\n\n\n<p>If a fan is oper\u00adated frequently at exces\u00adsive vibra\u00adtion levels, the bearing system may be damaged and prema\u00adture fail\u00adures may occur. Although vibra\u00adtions can be measured, it is not easy to stop them. Motor and fan specialist ebm-papst now solves this problem with its RadiPac centrifugal fans with auto\u00admatic reso\u00adnance detec\u00adtion: in as-deliv\u00adered condi\u00adtion, each RadiPac centrifugal fan has its own reso\u00adnance char\u00adac\u00adter\u00adis\u00adtics, induced, for example, by an unavoid\u00adable residual imbal\u00adance.<\/p>\n\n\n<div class=\"wp-block-image wp-image-16226 size-medium\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"660\" height=\"371\" src=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-660x371.jpg\" alt class=\"wp-image-16226\" srcset=\"https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-660x371.jpg 660w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-960x540.jpg 960w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-260x146.jpg 260w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-1536x864.jpg 1536w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-450x253.jpg 450w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN-300x169.jpg 300w, https:\/\/ebmpapst-7237.kxcdn.com\/en\/files\/2022\/07\/Fig_2_Vibration_characteristics_fan_EN.jpg 1920w\" sizes=\"auto, (max-width: 660px) 100vw, 660px\"><figcaption class=\"wp-element-caption\">Vibra\u00adtion char\u00adac\u00adter\u00adis\u00adtics of the fan.

High speeds ensure high air flow and high pres\u00adsures, meaning that even high-pres\u00adsure appli\u00adca\u00adtions can be covered.
