A venturi tube attachment for dusting in extreme conditions. The inner panel is used with the forced air source for the triggering of aspiration through the venturi tube of airborne dust from the ingress opening, a vacuum hose in communication with the atmosphere and the ingress opening by narrow air gap to synergistically combine the features of a forced air component and a vacuum component. The forced air component acting as a trigger at the egress end of the venturi tube to start aspiration through the venturi tube at its ingress end which is in close proximity by narrow air gap to the vacuum hose intake. The aspiration of the venturi draws in airborne dust quickly and from a greater distance than the vacuum component acting alone. The forced air component can be used with the venturi tube alone to direct airborne dust to the floor, open window, or door.
