140MM Dia Blower Fan Wheel

thingiverse

This is a 140MM Diameter, 65MM Wheel width, Blower Fan wheel, with a 31MM inset, and 7.8mm Round hole with retainer clips for a slotted washer and reverse thread nut to secure the fan. This was was made Specifically to replace the internal fan for the "Hot Side" of a Tripp Lite SRCOOL2KWM Rack mounted server AC unit. It is a few blades less due to differences in material strength and printer limitations vs injection molded parts. But should provide ample airflow to operate the unit normally. Feel free to modify as needed. This part is only printable with supports due to the inset of the mounting hole. PLA+ or ABS is strongly recommended. The part must be strong to survive the vibration stresses of high speed operation. Balancing is recommended, if you have the apparatus to perform the balancing. http://whiteglovefans.com/blog/2013/9/22/static-balancing-blades Balancing info (Manual)
