Abstract
The present invention relates to a hot air-generating device, combining a catalytic gas burner and a fan. According to the invention, on the one hand, the catalytic burner is of the induced-air type, for which means for mixing primary air in with the pressurized fuel gas are arranged upstream of the burner and, on the other hand, these same means comprise a component for drawing off oxidant air, independently of the circulation conduit which draws off primary air outside the latter. The invention can be applied to any kind of hot air-generating device, such as a hair drier and a hot-air gun for stripping paint.
