GMI has developped this useful accessory as a easy and efficient, low cost, vacuum generation source. This vacuum bag valve can be easily mounted on the vacuum bag. It is a Venturi-Pump that means that is necessitates only compressed air input. Low good vacuum level is obtained together with very good pumping flow.
• Optimum compressed air pressure : 5.5 bars (22.5 psi)
• Vacuum achieved : 87 % (-0.87 b/ 27 InHg)
• Flow at atmospheric pressure : 200 N Liter /mn 4.6 cfm
