The jet nozzle contains no moving parts, does not create any swirl, and is very lightweight. It expands the airflow from a connected air flow generator. The air exits from the tubular nozzles in the area of the plastic ring and mixes with the secondary air to form an overall airflow of large diameter. The jet nozzle is mounted on a handle; a hose for connecting to the air flow generator (see "Required") is included in the delivery.
