The Aria Free system delivers gradient sequential therapy with a pressure range of 45mmHG at the foot to 35mmHG at the thigh. This fixed preset eliminates the need for any adjustments in pressure. Aria Free is designed to target the lymphatic system with gentle gradient pressure, which should feel like the light touch of a manual lymph drainage (MLD) massage.
