Universal Diffuser Corp 1360 Garrison Ave., New York 59, N. Y. Manufacturers of FLEXIFLO Adjustable Diffusers Flexiflo-Type R and V Flexiflo-Type S Flexiflo-Series MP Flexifio-Adjustable Series IIAR VARIABLE EFFECTIVE AREA The FLEXIFLO diffuser is unique in that it has an infinitely variable effective area. All blades move simultaneously when the control knob is moved up or down. This provides a simple, effective means of controlling the volume of air. The pattern of diffusion for cooling pur poses remains constant on the Type "R" FLEXIFLO. For cooling and heat ing purposes the Type "V" FLEXIFLO provides a variable pattern of diffusion from horizontal to downflow. 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 blade configuration that gives a variable air distribution cone from horizontal to downward flow. Air can be delivered at practically any angle. Type S--For Side Wall or Ceiling Instal lations Model SC is for ceiling installations in cooling work. Model SW is for wall installations. Every Type S diffuser has one set of equalizing deflectors. Series MP--Multi-Pattern Diffusers FLEXIFLO Series MP diffusers are made to order in all rectangular shapes for one, two, three and four way blows to accommodate rooms of irregular shape. The diffusion pattern is parallel to the ceiling in all cases. Standard finish is metallic gray baked enamel. Other cqlors are available at no extra cost. Series H^R The FLEXIFLO HAR Series of adjust able square diffusers is built for either i ceiling or acoustical tile installation. The blades move simultaneously when the control knob is moved up and down. Air volume can thus be controlled with great precision and can be varied be tween near zero and full output at con stant horizontal pattern. 1464 I /' \ -y.
