Hot tub air controls are used to regulate the amount of air that is added to the hot tub's water jets. The air controls are usually located on the by the hot tub's control panel and consist of a valve or knob that can be adjusted to increase or decrease the amount of air being added to the water.
When the air controls are turned up, more air is added to the water jets, which can create a more intense massage experience. On the other hand, when the air controls are turned down, less air is added to the water jets, which can create a more gentle massage experience.
Air controls can also be used to balance the water pressure in the hot tub. If the water pressure is too high or too low, it can affect the performance of the jets, and make the massage experience less enjoyable. By adjusting the air controls, you can fine-tune the water pressure to ensure that the jets are working properly.
Some hot tubs also have additional air controls that allow you to customize the massage experience even further. For example, some hot tubs have "directional air controls" that allow you to direct the air flow from the jets to specific areas of the body, such as the back, legs, or feet. Other hot tubs have "zone air controls" that allow you to control the air flow from the jets in different areas of the hot tub, such as the seating area, the foot well, or the lounge.
It's important to note that the specific location and operation of the air controls can vary depending on the make and model of the hot tub. It's recommended to refer to the owner's manual of your hot tub to understand the specific location and operation of the air controls on your unit
