The AU exhaust nozzles are designed to capture the exhaust flow at the source without interfering with the airflow.
The AU exhaust nozzles are designed to capture the exhaust flow at the source without interfering with the airflow. This makes the nozzle highly suitable for service stations where the vehicles may be operated indoors for emission testing, according to TRGS-554 Jan-2019 and BAR-97 EIS Specification (July 2017). The edge of the nozzles are equipped with edge protection so accidental scratching can be prevented.
The AU nozzle is recommended for use in emission testing stations in combination with a Plymovent hose and fan.
