Air System Equipment Grfflea'r* The Independent Register Co. Established 1898 3747 East 93rd Street, Cleveland 5, Ohio AIR CONDITIONING REGISTERS AND GRILLES No. StlA-HMY Taniom With these grilles, compound deflections of air flows can be obtained with ac curacy and certainty. The directional adjustment can be made at the time of installing or after the grille is in position. Each vertical bar on the front may be individually adjusted for air flow right or left. The HMV valves on the back may be adjusted by the levers in front so as to direct the air flow up or down, or they may be fully closed. If width exceeds 24 in. the valves are made tandem as illustrated above. Adjustable Vertical Front Bars. Adjust able Horizontal Rear Bars. Key Control opposed blades for volume control attached. No. 311D`WG Bare Fixed Down These grilles are designed for com mercial installations. Style No. 311D-WG illustrated has grille bars set permanently at approximately 35 deg down. Other models available have grille bars set for straight flow. No. 17 Rear View Opposed blades for volume control. No. 60A For floor installations. Bars are set to iifluse the air up and out to both sides! Famous "Fabrikated" construction; excelling in rigidity, open area and fine appearance. Size shown 2J4 x 14. Other sizes are made and comply with code requirements of NWAH and ACA. 254 Air System Equipment jenn-Air Products Company, Inc. 1102 Stadium Drive, Indianapolis 7, Indiana Warehouse stocks in all major cities Roof Exhauster Equipment for Public, Commercial and Industrial Buildings QUIET-TESTED! Jenn-Air Quiet-Tested Roof Exhausters are pre-proved under simulated field conditions. Each unit must pass rigid inspection by the critical nVoibisreo,nvicibErayteio.n... is "screened" in Jenn-Air's Sound-Elec Test Chamber to detect Direct Drive Power Roof Exhauster Axial Roof Exhauster Dependable U-Spring Suspension - of Jenn-Air's Direct Drive Roof Exhauster virtually eliminates noise caused by vibration. U-Springs suspend the power assembly, isolate it from the base. Motor and blade are balanced together, elim inating vibration and noise. Heavy Gage All Aluminum Housing . . . Non-Over loading All Aluminum Wheel . . . assure trouble free performance. Low Contour. Streamlining meets requirements of modern building design. Jenn-Air's Ball Bearing Motor is lubricated for 10 years of continuous service. The Axial type Jenn-Air Roof Exhauster is recommended for general ventilation work and for duct-type applications where static pressures do not exceed onehalf inch. Special Non-Overloading Design protects against motor failures. Dependable U-Spring Suspension elim inates noise caused by vibration. USprings suspend the power assembly; isolate it from the base. Centrifugal Wall Exhauster Belt Drive Power Roof Exhauster Jenn-Air Centrifugal Wall Exhausters eliminate most duct work . . . provide a In this Quiet-Tested Belt Drive Power Roof Exhauster, Positive Weather-Proof Engineering is combined with trim Low Contour Design. Full Ball Bearing Drive and Motor are mounted out of the air stream. Heavy Gage All Aluminum Con struction gives strength without weight; Exhauster can be quickly, easily, disas sembled for re-assembly on the roof. All models come with a disconnect switch as integral part of the unit. Non-Overload ing Blade, dynamically and statically balanced, also assures long life, smooth, quiet operation. Jenn-Air's Sound-Elec Test Chamber, means of ventilation through the wall when roof exhausters would prove un suitable or more costly, as in multi-story construction. One single opening through the outer wall permits Wall Ex hauster to be connected directly to the area of ventilation . . . saves valuable interior space, lowers installation costs . . . reduces fire, explosion hazards. Con structed of heavy gage aluminum, ex hausters are completely weather-proof, unusually quiet. Dependable U-Spring Suspension eliminates noise caused by vibration. U-Springs suspend the power assembly; isolate it from the wall. where every Quiet-Tested Jenn-Air ex hauster is individually checked by the Vibronic Eye in a sound-control room * . line-lab tested for vibration, sound, motor load and insulation breakdown. Tests take the guess work out of noise Sound-Elec Test Chamber control--only units which pass this rigid inspection are accepted for shipment. . zy Jenn-Air Exhausters are rated in accordance with the Standard Test Code by the Texas Engineering Experiment station. 255
