Vacuum tweezer operates on compressed air

VIRTUAL INDUSTRIES STEALTH-VAC ELITE vacuum tweezer operates directly on 30 to 50psi filtered compressed air or nitrogen. The normally closed vacuum pen contains a whisper-quiet venturi vacuum generator that is activated only when the control button is depressed. This helps conserve factory-compressed air when the tool is not in use. The vacuum level can be controlled by adjusting the input pressure. With a 50 psi input, the vacuum level is 21 InHg with 2 lpm of free air flow. At 30 psi input, the vacuum level is 18 InHg with 1.75 lpm of free air flow and at 10 psi input, the vacuum level is 3 InHg with 0.75 lpm of free air flow.
