Commercial Centrifugal Scroll Fans, forward curved and backward curved impellers, different versions and sizes of double and single inlet fans available. Often classified by two numbers, eg. 10/10, 9/9 etc. This indicates the size of the scroll/squirrel cage impeller. ie. 10 inches long, 10 inches diameter. Closed motor or external rotor versions advised for dirty air.
