A pool air blower works by using a motor to move air, either by pulling it in (vacuuming) or pushing it out under pressure, and then expelling it through channels, primarily to help recirculate pool water.
Pool air blowers, similar to those used in industrial settings, play a key role in maintaining water circulation and often creating therapeutic bubbles in swimming pools or spas. Their fundamental operation is driven by an internal mechanism designed to efficiently handle air.
Understanding the Core Mechanism
The operation of a pool air blower can be broken down into a few steps, powered by its motor(s):
- Air Intake/Mobilization: At the heart of the blower are its motor or motors. These motors are responsible for initiating the air movement. According to the reference, thanks to the motor/motors in the device, the air is vacuumed or mobilized by pressurizing. This means the motor either creates a vacuum to draw air into the blower body or directly pressurizes the air within it.
- Air Handling within the Body: Once air is drawn in or pressurized inside the blower's housing (the blower body), it is prepared for expulsion. The specific internal design varies by blower type, but the goal is to build pressure or ensure a consistent flow.
- Air Expulsion: The handled air is then directed out of the blower. The reference states that the atmosphere in the blower body exits through the necessary channels. These channels are typically connected to plumbing that leads to the pool or spa, often ending at jets located along the bottom or sides.
Purpose and Function
The primary function mentioned in the reference is that blowers provide recirculation of pool water. While they don't move the bulk of the water like a main circulation pump, the injection of air creates bubbles and turbulence that helps to agitate the water. This agitation assists in:
- Mixing water, which can help distribute heat and chemicals.
- Creating a relaxing or therapeutic bubbling effect in spas and hot tubs.
- Enhancing the overall cleanliness and feel of the water.
In essence, the motor enables the blower to capture or pressurize air, contain it briefly, and then force it out through designated pathways into the pool water, serving the purpose of recirculation and aeration.
