👉 A bellows is a device used in air compression and heating, particularly for producing steam. It consists of two or more cylinders connected by a tube, which is heated to high temperatures through a gas-filled chamber. The steam produced from this chamber is then compressed using a piston, which draws the steam back into the cylinder, creating a vacuum that generates pressure. This process is known as compressing air. Bellows are commonly used in various applications such as heating plants, industrial processes, and household appliances
