OUND DIFFUSES G, A Series Cone Diffusers Introduction:, A Series Krueger s /A round ceiling diffusers provide excellent performance in variable air volume systems. The round ceiling diffusers have three or four cones depending on model selected to provide a uniform appearance regardless of design specifications. Krueger s round ceiling diffusers come in three styles. The first style, /, is used when vertical throw is not needed, but the consumer needs to adjust the room air induction. This is accomplished by utilizing the two position inner cones. At position one, capacity is maximized. In position two, room air induction is increased. The second style, 2/2/4/4, is used when horizontal and vertical discharge is required. This is accomplished by utilizing the three position inner cones. At position one, capacity is maximized and throw is horizontal. In position two, room air induction is increased and the throw remains horizontal. When set in position three, the air projects vertically from the diffuser. OUND DIFFUSES The third style, A2/A4, is used when horizontal and vertical discharge is required with infinite adjustability between horizontal and vertical. In the full open setting, capacity is maximized and throw is horizontal. In the full closed setting, air projects vertically from the diffuser. Krueger s round ceiling diffusers come with a safety cable to secure the inner cones after removal. (Safety cable is optional for 2 inlet size or smaller.)
