A gravity feed iron is a type of iron that is designed to use gravity to feed water into the steam chamber. It typically has a water tank that is mounted on the top or back of the iron, and a valve or spout that controls the flow of water into the steam chamber. As the iron is used, the water in the tank is heated and turns into steam, which is then used to press and smooth fabrics.

One of the main advantages of a gravity feed iron is that it allows you to easily refill the water tank without interrupting your ironing. You can simply pour water into the tank as needed, and the iron will continue to produce steam as you work. Gravity feed irons are also typically more lightweight and portable than other types of irons, as they do not have a large water reservoir built into the base.

Gravity feed irons are commonly used in a variety of settings, including home ironing, professional dry cleaning, and garment manufacturing. They are available in a range of sizes and styles, and they can be used with a variety of fabrics, including cotton, linen, silk, and wool.
