Weathervane brand drum industrial fan is not better? Rotating can run stand-alone, is a manufacturer of promotional packaging is another main focus. Rotating system of two-stage axial fan is the same diameter, counter-rotating to each other in series two single-stage impeller. Theoretically, at this time single-level traffic flow and the same pressure as the single-level 2-fold. Rotating stand-alone operation, it should be a rotating impeller running alone, that is, either Ⅱ stage impeller KⅡ shutdown, workers stage impeller KⅠ run; or KⅠ down, KⅡ run. In 2004, [28] the experimental study of the spin-alone operation states: seen from the performance curve, compared with KⅠ + KⅡ machine is running, the pressure KⅠ or KⅡ stand-alone operation, and efficiency curves have undergone fundamental changes that QI
