For vacuum bagging you will most likely want to add some form of check valve. The venturi itself is back venting and will let air back through the system when turned off. An inline valve would allow you to turn the venturi and air compressor off once the vacuum has been pulled. This would work well for a sealed vacuum bag. Unfortunately we do not have a valve kit available at this time.
