Wax-Filled Cylinder Operation
The cylinder contains a wax and oil mixture. As temperatures rise, the wax expands and pushes the piston rod outward. As temperatures fall, the wax contracts and the piston retracts. This movement allows the greenhouse window mechanism to respond to temperature changes as intended when installed within a compatible Gardening Naturally autovent system.
