Just include from the letters to individual rows then declare what type of fitting or duct that corresponds to.
Double deflection diffusers are outstanding vertical air throwers. They can tackle a higher airflow provide still remain quiet. Having said that, they don't seem to be ready to toss air so far as linear slot diffusers since the air will not be concentrated. However, double deflection diffusers remain well suited for most higher ceilings where by the ceiling top is about nine-12 meters.
