A hand held appliance including a wall, a fluid flow path extending within the wall from a fluid inlet into the appliance to a fluid outlet from the appliance, a fan unit extending longitudinally within the wall for drawing fluid into the fluid inlet wherein the fan unit is non-concentric with respect to the wall. The fan unit may be positioned coaxially within the fluid flow path. The wall has a thickness and the thickness of the wall may varies. The wall may be generally tubular and the thickness of the wall varies around a circumference of the wall. The wall may be generally tubular and has an inner surface and an outer surface. A central axis of the inner surface may be different to a central axis of the outer surface.
A hand held appliance comprising a wall having a cylindrical outer surface and an inner surface, the cylindrical outer surface having a central longitudinal axis, a fluid flow path extending within the wall from a fluid inlet into the appliance to a fluid outlet from the appliance, a fan extending longitudinally within the wall for drawing fluid into the fluid inlet, wherein the fan has a rotation axis that is the same as a central longitudinal axis of the inner surface of the wall and different than the central longitudinal axis of the cylindrical outer surface of the wall.
