, Series 3Cone Introduction: Series The series are square face, 3cone, round neck ceiling diffusers and are available in a variety of frame styles to help meet the architectural requirements of today s ceilings. The spacing of the inner cones in relation to the backpan result in a design possessing antismudge characteristics, preventing the buildup of particles on the ceiling, which is achieved by minimizing the low pressure region inherent to most way directional blow diffusers. lso known as concentric cone diffusers, s are constructed of onepiece stamped cones which provide a clean, smooth appearance without mitered corner joints. The series is an excellent variable air volume diffuser as represented in its throw characteristics at lower airflows; at typical flow rates, isothermal throws of 96 feet make this diffuser ideal for mounting centrally in many spaces while providing high mixing rates in the space.

PNEL SIZES 2 x2, 2 x2, 2 x2, and 2 x8 3x3mm and 6x6mm FETURES Three cones for optimum airflow control. Great choice for variable air volume spaces. Cones feature a onepiece stamped construction without mitered joints. Round neck for easy connection to round duct. ntismudge design prevents smeared ceilings. Two earthquake tabs are standard.
