• 1. The gas rod itself does not contain batteries and sensors, which need to be used with the window opener shelf.
• 2. When the ambient temperature rises, the thermal expansion increases the pressure in the gas rod, the gas rod slowly extends out, and the top window is opened.
• 3. When the ambient temperature drops, the internal pressure shrinks, the window opener spring pulls the gas rod back, and the window is closed, and the whole process is automatic without manual intervention.
