Design Medical Suction Controllers suit many applications. High Vacuum Suction Units are used in Operating Theatres, Intensive Care Units, A&E Departments, and Ward Areas. The controller can set the vacuum level between zero and the full vacuum pipeline. Low Vacuum Suction Units are used in Pediatric departments; the controller can set the vacuum level between zero but not exceeding (-150mmHg). Thoracic Suction Units are used where Abdominal or Pleural cavity drainage is required; the controller can set the vacuum level between zero but not exceed (-53mmHg)
