What Does a Pool Blower Do

Blowers mix the air and water and create a relaxing environment, particularly when used in conjunction with the hot tub’s jets.

How does a pool blower work?

An electric motor — directly coupled to an impeller (or impellers, in a multistage design) — adds energy to the flow of air passing through the blower as the motor spins. Result: The velocity and pressure of the air flow increase dramatically. Water pumps normally operate at 3,450 revolutions per minute.

What is the purpose of a blower in a spa?

Also called air pumps or bubblers, blowers push air into the spa through small ports or jets. This creates bubbles not unlike those in a glass of champagne. Although water pumps create strong pressure for the best massage, many enjoy the tingling feeling added by a blower.
