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.

Cooling system for a blower

Leaf blower that is carried on the back of the operator comprising at least an engine () and a fan. The fan is provided with an air inlet () placed on the side of the fan that is facing away from the back of the operator. The air stream is passing the engine () on its way to the air inlet () so that the engine () is cooled.

Leaf blower

Conventional leaf blowers have a supporting frame to where the different components are attached. In order to reduce the noise from the tool and protect some of the components are they provided with covers. This makes the tool heavy and complicated for the operator to use. The claimed invention is a covering casing () that also is the supporting structure for the different components in the tool. The casing reduces the amount of noise spread from the tool and protects the components inside the casing ().
