What is a Hot Tub Blower?


Hot tub blowers are also commonly referred to as air pumps or bubblers, as these names imply, a blower does just that, blows air into your hot tub water causing bubbling.

How does it work?

The blower is a unit that utilizes a fan to create air flow; it then forces the air through channels into the jets that allow for a release. The combination of air and water flow through the jets can provide a wonderful massage experience for the hot tub user.

What Do I Need to Know about a Blower?

If your spa does not currently use a blower and you are contemplating adding one, first of all you will want to make sure that your control pack will run a blower, it is a specific function that the control pack needs to be capable of operating. Also make sure you are ready to do the plumbing needed to connect in the air flow to your jets.

Also there are a few things to know that some people consider disadvantages of having a blower. The first is having the air injected into your water can cool down the water temperature and it does expend energy to have to keep reheating the water to maintain the higher temperature. Some people also find the blower running with the jets is too loud and interrupts there relaxation, but on the other hand many people count on the jets as their key to relaxation; so it all really comes down to personal preference.

If you already own a blower, they are a fairly simple piece of machinery that basically consists of a fan motor and housing. For this reason we recommend that if your unit goes out you replace the entire unit as it is much simpler and trying to just replace parts will offer little to no cost savings.

When looking for a new blower it is important to make sure you determine the correct voltage needed for your control unit, as they come in both 110V and 220V. Also, make sure your get the correct size to link up to your plumbing, usually 1.5” or 2”.

There are also different plug types available based on what type you need. Our Ultra and Max blowers include both a 4 FT Amp Cord and 4 Pin Plug. Our Silent Aire Blowers come with the option at checkout of a 3-pin Molded Plug, a 4-Pin Amp plug, a Gecko XM/XE 240 Volt Plug, or if you plan on hard-wiring and do not need a plug that is also an option.

How Can I Extend the Life of My Blower?

Premature blower failure is most often caused by water intrusion, there are a few ways to reduce the chance of water intrusion therefore extending the life of you spa blower. A Hartford loop in your plumbing that the use of a check valve will greatly decrease your chances of water intrusion, make sure that your installer/ technician uses both, it is also a recommendation that you replace your blower check valve anytime you replace your blower.

    My blower is connected to a one foot pipe and goes to the hole on the seats it is a old spa there’s no check valve or loop it’s mounted high by water line do I need to change everything to put valve in it doesn’t look like this type of tub was designed for a loop and check valve

      Thank you for your question. It is recommended to have a check valve to prevent water from getting into the blower. You don’t need a loop in the pipe as long as you have the check valve. Please let us know if we can help you with anything else.

    I have an old pdc spa. I just spent a lot of time and money trying to get it up and running. It was originally supposed to be free standing with a skirt around it. Then the previous owners built a deck around it. Now access is a nightmare. Anyway. My problem is that I have replaced the blower. It starts up. Sounds great. Was connected the same way as the previous blower. However, there is no sign of the air bubbles actually gettng into the spa. I have no idea what else to check. The blower is working fine. It has a check valve (installed correctly) attached to a 2 inch hose that goes up into the body of the spa. I don’t see any other tubes or valves near there other than the air valves from my jets that runs along the top of the spas inside. Any ideas? I’m at a loss. Thanks so much

      That’s a hard one to diagnose from a distance. If you aren’t getting any air bubbles when the blower turns on then I would assume that either the check valve is stuck closed or that there is something wrong with the blower. It isn’t likely that anything would be blocking the air lines. I wish I could diagnose the problem further but without being there to look at it the system it is hard to do. Good Luck, please let us know if you have any other questions!

    Hi:

    My blower has stopped working. The plug on my current blower is a four prong AMP plug with a green wire, white wire, empty prong, and black wire. With a voltmeter I measure voltage between the black wire and white wire of 120V. Since I have 120V going to the blower, I am thinking my blower is bad.

    My current blower motor says 240V on the label. This has me confused? Do I need to replace the blower with a 240V motor, or is a 110V motor really the correct application?

    Also, the outside diameter of my check valve that fits into the blower is 1 1/2 inches. I am not sure if I need a 1 1/2 inches blower or a 2 inches?

    Thank you for your help,

    Jerry

      Without being there I don’t really have a way to confirm what the voltage is on the blower you currently have. It isn’t likely that the blower would be labeled incorrectly but it is possible.

      The plumbing size would need to fit the diameter of the pipe the blower attaches to. If you purchased a 2″ blower and you really needed an 1 1/2″ you could simply put a reducer bushing on the plumbing to attach it to the pipe. It would definitely be easier to determine the pipe diameter and purchase a unit with the correct plumbing to begin with. If your check valve is 1 1/2″ then your plumbing is most likely the same.

      Please let us know if you have any other questions.
