Abstract
A blower having a fan mounted perpendicularly relative to an airflow discharge port. The fan is disposed within a volute formed in the housing at a rear area of the housing. This places the volute slightly behind the user's leg or hip when the blower is suspended or being held by a user along one side of the user's body. This significantly increases the ergonomics, efficiency and comfort of the blower by allowing the blower to rest more comfortably along the user's side without interference from the volute portion of the housing. This also allows the motor to be located directly underneath the handle of the housing to provide a better balance and feel to the housing when the user is holding onto the blower via the handle.
