The fan assembly () may be operably coupled to the motor () to force air through a blower tube () responsive to operation of the motor (). The blower tube () may define a tube axis (). The inlet assembly () may provide a path for air to the fan assembly (). The inlet assembly () may include an inlet aperture () formed at an end of the housing (). The inlet assembly () may further include an inlet mesh () disposed within the housing () spaced apart from the inlet aperture ().

Blower with improved sound reduction

A method of cooling blower components may include rotating a fan assembly () responsive to operation of a motor (). The rotation of the fan assembly may create an underpressure region in an inlet portion () and an overpressure region at a main channel () of the fan assembly (). The method may further include drawing air into the inlet portion () through a control unit housing portion () of a housing () of the blower () to cool a control unit () of the blower (), drawing air into the inlet portion () through a battery compartment () to cool a battery () of the blower (), and pushing air from the main channel () through a motor housing () to cool the motor ().
