How does an air blower work in a spa?
In simple terms, think of the air blower as nothing more than an air pump, forcing a thin fluid — air — through a piping system.In a spa, the piping system may lead to an air channel or air injectors installed in the floor, seat or walls; or, it might be connected to the hydrotherapy jets in a manner that will enhance their hydro-massaging operation. Various valve arrangements allow blowers to serve double duty, feeding an air channel for basic bubbling and acting as a hydrotherapy-jet booster, often referred to as “turbo-charging.”
How many degrees does a spa blower turn?
The number of 90-degree turns: Remember these turns add to the work a blower must do to force air into the spa.Water depth: Water pressure bearing down into the air channel or air injectors must be countered by the force of the air pushed through the piping.

This minimizes the temperature differential between the water circulating in the spa and the (often) much cooler air being drawn into the system — increasing user comfort and easing the heating burden on the spa’s primary heater.
