260 Air System Equipment RmI Vfntilrttn WESTERN ENGINEERING & MFG. CO P.O. Box 66455, Los Angeles 66, California Factory: 4114 Glencoe Avenue, Venice, California Representatives in Principal Cities (Established 1921) Western Roof Ventilators have been installed throughout the world. Since 1921 Western Air Engineers have improved and designed new ventilators as new facilities demanded-new adap tations. Representative models are described here briefly. See complete catalog in Sweet's Architectural File, Sweet's In dustrial Construction File and Western States A-E-C Catalog [File. I. Western Rotary with lifetime bearing guarantee. High ex haust capacity. Continuous motion. Storm proof- No back -draft. Enclosed, long life lubrication. 2: Westemaire low sillhouette Hooded Exhaust Ventilator is a high efficiency power unit engineered into a low, weather proof, streamlined housing to go with modem architecture. Heavy gage steel, aluminum or non-corrosive Fiberglas.* 3. Westemaire low silhouette Vertical Exhaust Ventilator is a high capacity power unit for vertical air discharge___designed . specifically for industrial usage in high velocity discharge of fumes, smoke, dust laden and foul air. Completely weather proof. 4. Forbes Syphonaire. Certified capacity ratings. Government projects approved. Low design Rigid construction. Attractive. 5. Forbes Amvent. Fills government specifications for station ary roof ventilator. Write for complete engineering information. 6. Forbes Econovent. Rugged design of finest ventilators. En gineered construction at low price. Certified capacity ratings. 7. Western Airout. Directional stormproof type ventilator with lifetime guaranteed bearing suspension. Exhaust capacities cer tified. 8. Westemaire Curb Mounted Fan is a fan assembly mounted in a square-to-round base to be used with any Western Venti lator where excessive air contamination requires power opera tion during peak periods. Increases capacity, lower height, re- duces vent throat size. Sealed-in motor unit. 9. The Westemaire Booster Fan fits any Western Ventilator and may be added after the original installation. Available as a high speed, high velocity industrial unit or slow speed, quiet operating, commercial structure. 10. Western Transaire Ventilators provide continuity of roof appearance. Units available in gravity, power, intake or exhaust types, all engineered into the same low silhouette housing for clean roof design. II. Western Continuous Ridge Ventilator exhausts tremendous volumes of foul air and heat. Made in any length. Stormproof, excellent drainage, efficient, heavy construction. 12. Low silhouette Western Thermoflow Unit Ventilator... a gravity type for exhausting tremendous masses of air by the convection principle. Engineered for heavy industrial applica tions. Installed on schools, warehouses or factories, the units are relatively inconspicuous. Standard unit is 7 ft 6 in. wide and 10 ft long, only 21V4 in. low, and has three operating cells. May be installed singly, multiples.side by side, multiples end .to end, or multiples of double units. 13. Solar&ire modifications for all stationary ventilators are available to provide "sky-light ventilators." Standard units em ploy translucent Fiberglas* top-plates to allow the entrance of daylight into building areas. If dampers are required, they are also fabricated of Fiberglas.* *TM Owens Coming Fiberglas Corporation Air System.
