Dual purpose product for blowing dust out of hard to reach areas or for freezing. In position with the valve up, a strong stream of compressed air blows out dust from hard to reach places. When the container is inverted by 180° with the valve facing down, it works as a freezer, e.g. making it easier to assemble small, tightly fitting parts or to detect defects in electronic components. Disconnect electrical equipment before use and take precautions against electrostatic discharge.
