Inquiry (采购产品): Operating Heat Range I am looking at an application for an airfoil wheel plug fan with an arrangement 4. What is the maximum temperature range for this type of application. Can you put a shaft cooler on the shaft. If so what is the increase in temperature operating range. **** Hidden Message ***** Ken Moran 2400 E.
