Airflow Valve

This airflow valve can be used in conjunction with diaphragms to build mechanical respirators (ventilators) and can also be used in conjunction with ultrasonic nebulizers to divert the air exhaled from the lungs of people with COVID 19 to a filter to avoid contamination of the environment. There are some pictures with suggested use. All connections respect the standard of 22 mm hoses and the inlet and outlet valves can be changed for a better adaptation to the project. In my tests it´s better to put the exaust valve directly in front of the in/out connection.
