GLEN-VENT app for iPhone and iPad

Glen Vents and flow resistance refer to some existing vents that use air directing elements to form at least two channels for directing vertical airflow, by using flat baffles to regulate the airflow in both channels. Air conditioning elements are not Aerodynamically based, i.e. it does not appear as an extension of the air guiding element in the direction of the air intake and obstructs the airflow when it is in an intermediate or open position, which is the airflow in the two channels Location of the same airflow adjustment element.
