Hi-Temp blower fans

Any bushing/bearing special requirement ? For example I bought this 80 cfm blower, for a cyclone project, not yet started, so no feedback so far: https://www.ebay....2364909396

If I?m sucking air from drum I?m afraid air will be too hot for the lesser fan? https://www.grainger.com/product/1TDP2?cm_mmc=Share:MOB_Message-_-iPhone_IDPShare-_-1TDP2 https://www.grainger.com/product/1TDU9?cm_mmc=Share:MOB_Message-_-iPhone_IDPShare-_-1TDU9
