ABSTRACT:
An impeller formed from sheet-metal by stamping and bending, at a low production cost, capable of delivering an increased quantity of air at a reduced noise level and with reduced power consumption and enhanced efficiency. The method of manufacturing the impeller from sheet metal incorporates sufficient versitility to allow the blades of the impeller to be formed to any desired configuration in order to provide an optimum shape for the intended impeller use. The blades can be curved or twisted and can extend perpendicular from the sheet-metal surface or at any desired angle for optimum utilization.
