Air System Equipment Air Diffusers Universal Diffuser Corp. 890 Whittier St., New York 59, N. Y. Manufacturers of FLEXIFLO Adjustable Diffusers Flexiflu-Typc R VARIABLE EFFECTIVE AREA The FLEXIFLO diffuser is unique in that it has an infinitely variable effective area. All the blades move simultaneously when the control knob is rotated. This provides a simple and effective means of controlling the volume of air. The pattern of diffusion for cooling purposes will remain constant on the Type "R" FLEXIFLO. For cooling and heating purposes the Type "V" FLEXIFLO will provide a variable pattern of diffusion from horizontal to downflow. Flexiflo-Type S Built-in Equalizer Deflector Type R--For Cooling Provides a diffusion pattern and radius of diffusion that are not altered by change in air volume. Air leaving the Type R diffuser always travels parallel to the ceiling, assuring satisfactory per formance under all operating conditions. Type V--For Cooling, Ventilating and Heating Has a special configuration of the blades that gives a variable air distribution cone from horizontal to downward flow. Thus air can be delivered at practically any angle. Type CH--For Heating, Ventilating and Cooling Has concentric supply and return out lets with outer and inner portions con nected by sliding collars, the lower one fastened to the blades and the upper to the cross bar. The lower collar has a flared edge like the blades so that the delivery of air is shunted outward and peripherally, preventing short-circuiting of the room air. Type S--For Side Wall or Ceiling Instal lations Model SC is designed for ceiling installa tions in cooling work. Model SW is designed for wall installations. Every Type S diffuser has one set of equalizing deflectors. 1338 Air System Equipment Air Flow Remutors Young Regulator Company 5209 Euclid Avenue, Cleveland 3, Ohio DAMPER-REGULATORS; REMOTE CONTROLS SYSTEMS Sales Representatives in Principal Cities YOUNG DAMPER REGULATORS Meet practically every condition where control of air volume is required.
