Topring 60.465 TOPGUN Extra Thrust Safety Blow Gun Venturi Nozzle 12 Inch

Designed to move a large volume of debris through the venturi nozzle increasing the available air thrust by 40% compared to conventional blow guns. Should the tip of the nozzle be blocked, the entire airflow is diverted through the side openings so the static pressure remains under 30 PSI (meeting OSHA standards).
