Cooling with blowers by SEPA EUROPE is child’s play and simply because they are excellent in overcoming obstacles. In this particular case by overcoming frictional resistance because radial fans suction in the air and blow it out again at a 90°angle°. They are thus in the position to provide a high flow rate even in the event of high pressure loss.
There is hardly another mechanical component that has such diverse usage as a finger guard.
Fan sleeves are an underestimated accessory as far as electronics cooling is concerned. When applied correctly however, they can avoid the transmission of vibrations and oscillations and significantly reduce the noise development. If you only require small quantities in special dimensions then production using innovative 3D printing would lend itself to this purpose.
