SR fans are thought to be employed in applications that require low noise emission levels, like radiators and engine coolers.
550 -1100 mm 
20°-37,5° T -40° C to +120° C° SR impellers are manufactured assembling sickle profile blades, with a light aluminum alloy hub. The impellers are thought to be employed in applications that require low noise emission levels. The impellers can be assembled with 3/5/6/8 blades, using TM family hubs for 5/9/12/16 blades. Blades have variable right setting angles ranging from 20° to 37,5°, and can produce a sucking or blowing air flow.
