Air blowers are responsible for making the bubbles on your tub water. A lot of people find it more relaxing to have them. It is important to check if your control pack can handle air blowers before purchasing one for your spa or hot tub.
For existing owners, water intrusion can damage the blowers and you may need to replace it.
It's a good thing that PST Pool Supplies stock good quality air blowers with different specifications. Just make sure to check the power supply if you need to buy a 115v or 230v blower. If you are unsure please let us assist you by calling us at: 866-535-0899.
