Medium Pressure Centrifugal Fans: Backward Curved Benefits

What is a backward curved centrifugal fan? The backward curved centrifugal fan design uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is known as the fan wheel, and often includes other components with aerodynamic or structural functions. The centrifugal fan wheel is typically contained within a scroll-shaped fan housing. How does a backward curved centrifugal fan work? Backward cu...


Enclosure Ventilation – An Axair Guide to Power Electronics Cooling

Fan filter kits have been in use for around 20 years and are now considered ‘part of the scenery’ and a commodity product.
