"Axial Fan" suction chamber similar to the centrifugal fan, the only two kinds of non-free gas collector and into the freedom of the intake air into the tank. Power plant boiler feed, Fan are set airbox. Airflow from the airbox intake air flows into the radial rim, then turning in the annular flow path through the current collector (convergence device) into the impeller. Airbox and the current collector and the structural requirements of the role is to make a steady air flow evenly into the soil under the wheel with minimal loss. Fairing mounted on the front wheel or inlet guide vanes, so that the inlet conditions more perfect, reduce fan noise. The quality of the fairing great influence on the performance of the fan, which is generally designed as a semicircular or semi-elliptical, can also be expanded and the rear pressure inside the cylinder is designed to streamline together.
