The airflow charge is not the similar point as velocity. Velocity refers to simply how much ground air handles relative to time. Meanwhile, the airflow charge highlights air output because it relates to time.
Double deflection diffusers are excellent vertical air throwers. They will handle a significant airflow supply however stay quiet. However, they are not able to toss air so far as linear slot diffusers since the air is not concentrated. Even so, double deflection diffusers are still appropriate for most high ceilings where by the ceiling peak is about 9-twelve meters.
