Properly placed behind the ornamental grille, the deflecting vanes of the Bulator give the air throw and spread specified by the engineer. The vanes are adjust able so that the air flow can be deflected to right or left, up or down, or in a combination of directions. Although mounted just behind the ornamental metal grille, the deflecting grille is not noticeable, as will be seen from the illustration, made from an un retouched photograph. deflecting vanes, have little effect on the air stream pattern and air throw. Using a 24 im wide by 8 in. high combi nation of control louvers, vertical de flecting vanes, set 45 each way, and a metal grille with 65 per cent open area, the tests showed the following resistance pressure in inches of water: Air flow volume cubic feet per minute 400 500 800 1000 1200 Total throw of air stream in feet 5.5 8.2 10.9 13.6 16.4 Resistance pressure with grille attached 0.03* . 0.08* 0.13* 0.21* 0.29* Tests made at the Case Institute of Technology, Cleveland, under the direc tion of Professor G.

Hendrick Manufacturing Company Air System Equipment < Grilles ; HENDRICK PERFORATED METAL GRILLES Hendrick decorative grilles are fur nished in over a hundred patterns, and in a wide variety of overall dimensions, bar sizes, and number and size of per forations. -- Many exclusive Hendrick designs, orig inally produced to meet an architect's specifications for some particular proj ect, are now available as standard numbers, and facilities for making spe cial designs to specifications make the Hendrick service even more complete. The wide range of patterns permits the choice of a grille that will harmonize with any style of architectural design or period construction. Arglin--63 per cent Open Area Grilles are fabricated in heavy-gauge aluminum, bronze, copper, Monel, steel, stainless steel, and other commercially rolled metals. With ample open areas and accurate sizes, Hendrick grilles are characterized by clean-cut perforations, fine finish, and freedom from burrs and other imperfections. They are easy to install, and always lie flat because of a special flattening opera tion in their manufacture. ,- ; Argive--60 per cent Open Area lOT MIW! PI pal PJi!

All types are furnished with either horizontal or vertical directional bars. The standard mesh can either be fur nished with grille bars permanently set at the factory for straight or directional air flow, or furnished so that the grille bars may be individually adjusted on the job to direct air flow to any desired degree.
