Fans are easy a set screw holds the shaft or a hex nut make sure to get the same pitch and diameter they can … What can be done. Blade pitch is the angle at which the blades are set relative to parallel to the ground. It is always best to check the specs on the fan blade before replacing the condenser fan motor on any unit, and especially on older models. Pitch is measured at the spider/lobe, not on the blade, and it's common for fan blades to have slightly different pitches and still achieve the same performance. I don't think 5mm or so on the blade length will make that big a difference in the calculations. The condensing coil is the part the fan draws air through. 0000004306 00000 n 0000009280 00000 n Another way of looking at it is that the fan is moving an 800-foot-long column of air that is 1 foot in diameter through space each minute. h�bbbd`b``Ń3�E� �� endstream endobj 113 0 obj <>/Metadata 6 0 R/PageLabels 3 0 R/Pages 5 0 R/StructTreeRoot 8 0 R/Type/Catalog/ViewerPreferences<>>> endobj 114 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/StructParents 0/TrimBox[9.0 9.0 603.0 783.0]/Type/Page>> endobj 115 0 obj <> endobj 116 0 obj <> endobj 117 0 obj [/ICCBased 129 0 R] endobj 118 0 obj <>stream Click the part number and you’re done.
