T Dgi hi "products" BAGITAIR DIFFUSERS Agents in All Principal Cities Square or Rectangular in Shape Type A Western Rotary Efficiency: Extremely high exhaust ca pacity due to "backward curved blower wheel" type mechanism. Momentum operates the Western Rotary Ventilator between wind peaks when any stationary ventilator is inoperative. Capacities certified by a foremost uni versity laboratory. (See results in our catalog.) CERTIFIED CAPACITY RATINGS (See our complete catalog) Bulk, height, weight and cost are below other types yielding comparable capa cities. Weight is important when de signing roof loading. Appearance: Modem functional design adds beauty. No guy wires needed. Guarantee: Bearings are guaranteed for ventilator life. Sizes: Available from stock in sizes 6 in. through 48 in. Forbes Syphonalre Efficiency: Exhausts high volume. Will not backdraft. Tests of a foremost uni versity laboratory show the outstanding capabilities. Openings exposed to wind will lower efficiency in a stationary venti lator. The Forbes Syphonaire has a solid 360 degree wind-band to prevent this possibility. CERTIFIED CAPACITY RATINGS (See our complete catalog in Sweet's) Bulk: Low design, light in weight. Appearance: Modern, attractive, no guy wires needed. Projects: Used for many Government projects. Sizes: Fabricated from galvanized iron. Also available in aluminum and copper or stainless steel. Sizes from 6 in. through 48 in. Westemalre Curb-Mounted Fan May be used with any ventilator of same throat size to increase exhaust volume. High speed-High velocity or Slow SpeedQUIET Operation. For fumes, smokes, dust or excessive heat.

ACOUSTICAL CEILINGS TheAGITAIR Type RTC square or rec tangular in shape is especially designed for installation in acoustical ceilings. Made in sizes to conform to standard tile dimensions. AGITAIR WIND-ACTUATED ii EXHAUSTERS Provide proper ventilation regardless of wind direction, and with positive elimi nation of down-draft. Functions at peak efficiency at average low wind ve locities. Will not restrict the flow of air or gases when there is no movement of out door air across the head. Fan-equipped units also for higher rat ings. 1263
