Your hot tub’s air blower uses a fan to create air flow and then channels that air flow through the jets in your tub or spa. It is sometimes referred to as an “air pump” or “bubbler” because it is the force behind the bubbling in the water — different from a hot tub jet. If you’ve had your hot tub or spa for a while now, then it may be time to install a replacement air blower. We carry hot tub and spa blowers from many top brands, including Zodiac and Air Supply of the Future. Many of our models come with inbuilt silencers so you can enjoy your hot tub or spa’s bubbles without the noise characteristic of many older air blowers.
