Abstract
Arrangement in a blower including at least an engine and a fan, the fan includes a fan housing enclosing a fan wheel and a fan inlet. The engine and fan are surrounded by a casing provided with an air inlet to let air in to the fan inlet placed inside the casing. The air stream from the air inlet in the housing to the fan inlet cools the engine and components inside the casing before it enters the fan inlet and leaves the blower via a blower tube. The fan housing is provided with an opening () placed in the fan housing so that air is allowed to leave the fan in case of blocked air stream in the fan outlet or blower tube.
