Centrifugal Scroll Fans

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.
Also known as snail fans.
These need an enclosure to operate and are normally at one end of a system. For inline commercial fans, see our Centrifugal & MixVent Fans or industrial section. for larger units.
