The RELAX IMPACT system is designed to give a relaxing massage. All of the spas that come with this optional feature have an additional massage pump that drives air through the nozzles placed around the leg area.
As the air bubbles generate impact on the body, they produce a relaxing and stimulating effect.
This is the best way of relaxing muscles after a workout.
A standalone massage pump is used to give this type of massage and it works on a separate circuit to that used by the water massage jets.
