This device is particularly suitable for the use of tubes with internal diameters of less than3 mm and allows an air flow to pass through them so that they can be introduced into the Dosaset solvent dosing bushings, without these filling up, thus avoiding possible occlusions.
The air outlet flow is limited by fixed bottlenecks inside the AST body and by the inlet pressure adjustment carried out by means of a reducer positioned at the rear: the outlet air adjustment pressure is displayed by the pointer pressure gauge positioned at the front of the device.
