TOPGUN Protective Air Screen Safety Blow Gun

Blow gun with amplified air jet Nzl: the air flow accelerates as it passes through the tip, drawing in ambient air through the side openings. The increased speed and volume of air ejected produce a much higher thrust.Part of the main air stream is deflected through slots at the Nzl’s periphery to form an air screen that protects against the return of debris and dust.In the event of tip obstruction, air escapes through the side openings, keeping static pressure below 30 PSI.The flow control screw enables air flow to be reduced for delicate work.Built-in hook on blow gun body for easy storage and easy access.
