Abstract
An air treatment appliance for treating surrounding air including a body. A spider-mount mounted to the body has a motor mounted thereto in cantilever fashion. A fan attached to the motor may be a radial fan, and is operable to draw in surrounding air and cause it to flow through the appliance. A grommet between the motor and the spider-mount dampens vibrations from the motor. A filtering mechanism in the path of the airflow helps filter out undesirable material from the surrounding air. A radial airflow guide downstream from the fan efficiently guides the airflow to be expelled in a predetermined direction. The motor is at least partially accommodated by the spider-mount and the fan. The apparatus results in reduced noise and vibration during operation of the appliance.
