Reading a fan curve
WebApr 1, 2024 · Reading a fan curve (correctly) is a skill worth possessing, as it allows those who select and specify fans to understand the performance characteristics and capabilities of different equipment so they may determine the fan that best suits the requirements of an application. For them, this article will help to straighten out fan curves. Webthe point of operation will lie somewhere on the fan curve (sometimes even this is in doubt depending on the duct geometry, which will be explained later). Where along the fan curve the operating point lies depends entirely on the ductwork. The fan will operate at the place where the system line intersects the fan curve. System Effects
