Diffuser throw refers to the distance that conditioned air travels from a register or grille before it slows down to a specific speed. Proper throw is essential for ensuring that the air reaches all corners of a room rather than just dumping it right below the vent. In Ceiling Cassettes, the throw is designed to move air along the ceiling and down the walls to provide a gentle, even cooling effect. If the throw is too short, the center of the room will be cold while the perimeter remains warm; if it's too long, it can create uncomfortable drafts. Engineers use throw data to determine the best placement for Ducted registers in a new floor plan. You can adjust the throw on many of our Filter Grille products to customize the airflow for your specific room layout. Achieving the perfect throw ensures that every square inch of your home benefits from your ACIq system. It is a critical factor in the science of air distribution and occupant comfort.
