Through a compact and handy design, built-in battery and convenient foldaway handle, Flow Kleaner ensures an optimal clearance throughout the entire bronchial tree for adult and pediatric patients. Beside the innovative suction system, EFA ^® technology allows a deep, safe and comfortable airways clearance, purely by means of expiratory flow acceleration. EFA ^® technology decreases the need for intervention with deep aspirations, that often cause discomfort and sometimes are even harmful for the patients.
