Terminal selection

Grille, diffuser or nozzle.

Perimeter and sill installations want grilles: aimable blades that direct air along a surface. Occupied ceilings want diffusers: swirl or radial faces that mix air into the room within a short distance. Very tall or long spaces want jet nozzles: focused columns that keep their energy across throws ordinary terminals cannot reach. Exhaust points want disk valves.

TerminalDischarge patternBest forKeep it away from
Grille (single / double deflection)Flat, aimable sheet of airPerimeter and sill supply, return and exhaust, under-window runsWide occupied ceilings, where mixing matters more than aim

Longer answers: grille or diffuser? and what throw distance really means. The terminals live in Air Distribution Products; the valves that balance them in Air Control Products.
