A dual-purpose product for blowing dust out of hard-to-reach places or freezing. In the valve up position, a strong stream of compressed air blows dust from hard-to-reach places, and after turning the container by 180° with the valve down, it acts as a freezer, facilitating, for example, the assembly of small tight-fitting elements or detecting damage in electronic components .Before use, disconnect electrical devices from the power supply and take precautions against electrostatic discharges.
