Exploring the Spa Bubble System—The Key to Enhance Your Hydrotherapy Experience
When you step into a spa, you're most likely captivated and delighted by the delicate, continuous bubbles constantly being sprayed. But have you ever wondered where these soothing bubbles come from? How are they generated? Or why your spa doesn't produce a consistent, dense stream of bubbles? This article will take you on a journey to explore the spa bubble system, a key component that greatly enhances your overall hydrotherapy experience.
Where Do the Bubbles in the Spa Come From?
The bubbles generated by the water-air mixing of the spa whirlpool system are not the only source of bubbles in a spa. As the name suggests, the bubble system is also one of the main systems responsible for generating bubbles in the bathtub [ bubble spa / hot tub with bubbles ].
·The spa whirlpool system provides water flow power through the water pump, introducing air into the water stream via the air regulator. The specially designed water jets mix the water flow with the air to create bubbles. Additionally, by adjusting the air regulator, users can control the intensity and density of the water flow and bubbles, thus customizing different whirlpool massage experiences.
·While the bubble system, also known as the air bubble massage system or air therapy system, is a system that provides a massage effect by generating a large number of bubbles in the water. It is an all-around comfortable massage device that integrates air jets, a high-efficiency blower, precision air manifolds, a check valve, durable hoses, and stable hose clamps. Powered by the strong force of the blower, the air is precisely and steadily delivered to each air jet, generating fine and dense smooth bubbles that cover your body thoroughly.
Detailed Introduction of the Spa Bubble System Components
Spa Blower
Activated by the air switch or the electric control system, the spa blower draws in external dry air. The electric motor inside the pump drives the fan impeller to rotate, generating airflow and pressurizing it. The air is then released through the blower’s outlet into the hoses until it exits through the air jets.
To understand spa blower, you should focus on the parameters are:
| Parameter | Unit | Parameter | Unit |
| Noise Level | dB(A) | Max Air Pressure | Mpa |
| Available Jets Qty | pc | Air volume | m3/min |
| Power | kW | Recommended water depth | m |
Current | A | Max working pressure | MPa |
Environmental temperature | ℃ | Recognize certified | UL/ETL/CE/TUV/SAA/ROHS... |
Among them, spa blower maximum air pressure and maximum working pressure, although both are referred to as "pressure," represent completely different concepts:
·Maximum air pressure: This refers to the highest air pressure the blower can reach during operation, indicating the blower's maximum ability to push air into the bubble system. It is typically used to measure the performance strength of the spa blower. The higher the air pressure, resulting in the stronger and denser the bubbles, the more intense bubble massage effect.
·Maximum working pressure: This refers to the highest pressure that the entire spa system can safely handle without causing damage, representing the critical pressure threshold at which the system remains undamaged. It is typically used to confirm whether the spa system operates within safe parameters.
Hoses and Clamps：
Main Air Hose
This is the primary pipeline for air circulation in the spa bubble system, which can compress and transport the air produced by the blower to other sub-pipes or air jets. The main air hose is characterized by large diameter and long length, typically made of PVC or TPE, ensuring it is more durable and robust.
Other Air Hoses
These hoses are used to connect the main air hose to the individual air jet. They are characterized by smaller diameters and are more numerous and widely distributed throughout the system. They are typically made of PVC or PU. (Larger diameter hoses may also be used in the main air hose).
Hose clamps
These are used to secure the hoses to the air jets, air regulators, or blower connections, ensuring there is no air leakage. They are typically made of metal (e.g. stainless steel) or plastic.
Air Manifold:
The air manifold in the spa bubble system connects the main air hoses to multiple branch hoses, ensuring each air jet receives a stable air supply through even distribution and pressure balance. Air manifolds are typically made of high-pressure resistant, corrosion-resistant engineering plastics such as PVC, ABS, or PP.
Spa quick coupling air manifold
The air manifold connection usually uses quick couplings to connect branch air hoses, and some of them are featuring built-in quick connectors. The flexible expandability and ease of installation of air manifolds dramatically increase the maintainability and adaptability of the system.
Check Valve:
Principle: Typically designed with a one-way spring mechanism, the valve opens when the airflow is in the forward direction and closes when the airflow is reversed.
Function: It is used to prevent accidental backflow of air or water, which could damage the blower or pollute the water.
Material: The valve body is usually made of plastic (e.g. PP, POM) or metal (e.g. stainless steel), and the internal sealing ring is made of rubber or silicone.
Installation: It is typically installed between the blower and the air manifold or before air jets. Installation should be in accordance with the direction of airflow marked on the valve in order to effectively prevent gas backflow.
The spa air jets are evenly distributed along the bottom and sidewalls of the spa, injecting high-pressure air produced by the blower into the water, creating a large number of fine bubbles that provide a full-body massage effect. The air jet’s main body is usually made of copper, with a small portion made of plastic. The cover material options include ABS (plated), stainless steel, and copper. Additionally, it's important to note that spa air jets and the pipeline system typically do not have quick connectors, which differs from bathtubs.
What Indicates That Your Spa Bubble System Needs Maintenance and How to Fix It?
·Bubbles in the spa become fewer or even disappear
Blower: Insufficient power, reduced efficiency, resulting in insufficient air supply.
Hoses: Poor air circulation, resulting in unsatisfactory bubble formation.
Air jets: Blocked by scale, impurities, or grease, resulting in gas that can not be sprayed smoothly.
·Abnormal sound of spa bubble system operation
Blower: Malfunction or impeller damage.
Hoses: Loose pipe joints and connectors can cause vibration and unusual noise when air flows through.
Air jets: Clogged jets lead to poor airflow and abnormal noises.
·Spa bubble system stops working
Electric control: Power not properly connected, or malfunctioning controller/control panel.
Blower: The pump overheats and activates automatic protection, causing it to stop running.
How to maintain the spa bubble system properly?
1. Regular Cleaning: Keep the air inlet of the blower, hoses and jets clean to avoid accumulation of debris and scale.
2. Checking the electrical controls: Ensure that the circuits are properly connected and that the control panel performs well
3. Reinforce the hoses: In addition to cleaning, the hoses and connections need to be checked for tightness.
4. Prevent backflow: Regularly check if the spring in the check valve is aging or if the seal ring is damaged.
A well-maintained bubble system should always deliver consistent, gentle bubbles.
If you're not sure what the problem is, or if you're experiencing a complex malfunction, it's best to contact a maintenance professional for inspection and repair. This will ensure that your spa bubble system stays in top condition for a long time, delivering the best spa experience!
