Air System Equipment Ventilators Western Engineering & Mfg. Co. ESTABLISHED 4112 Glencoe Ave. 1921 Venice, Calif. - Representatives in Principal Cities HIGH EFFICIENCY ROOF VENTILATORS Westem Rotary Ventilator High exhaust capacity for relatively small bulk in weight. Remains in con tinuous motion between gusts, and is stormproof. It cannot backdraft because the throat velocity rises at an increasing rate with the wind speed. Wind tunnel tested. Rigid center support, and vibra tion absorptive rubber mountings, quiet performance. Enclosed, long-life lubrica tion, and durable hammertone sea-green finish. Sizes: 6 in. to 48 in. inclusive. Western Continuous Ridge Ventilator For high volume, low velocity exhaust capitalizing on air movement generated by temperature difference plus induced draft, this ventilator provides a continu ous opening of any length desired in 17 throat sizes. The structure is storm and rain proof and is available with or with out adjustable dampers and screens. In herent characteristics qualify this venti lator for use in factories, foundries,.mills and similar buildings. Forbes Syphonaire A highly-engineered stationary type roof ventilator employing a circular wind band that prevents the entrance of out side air. High capacity, rain and storm proof, rugged construction, and low silhouette, obviating the need for guy wires. Wind tunnel tested by aeronauti cal laboratory. Sizes range from 6 in. to 48 in. inclusive. Westemaire Curb-mounted Fan For low cost air movement under low static conditions, this unit is designed to meet practically every application in volving a roof-mounted exhaust fan. High speed, high velocity for industrial use or slow speed, quiet operation for commercial use. Available in 39 models. 8 in. to 48 in. Can be used in conjunction with any type gravity ventilator.

GALVANIZED STEEL for high quality results and ease of fabrication U.S.S. Galvanized Steel Sheets are espe cially processed for the jobs they have to handle. They arejmiform in flatness and surface. They can be bent, cut, stamped, rolled and formed--all with unusual ease of handling. In the pro duction of U.S.S. Galvanized Steel . Sheets careful attention is paid to the adherence of the zinc coating. This is done in order that forming operations may not fracture or flake the coating and thereby expose the base metal to atmospheric corrosion and rust. Because of all these outstanding quali ties, U.S.S. Galvanized Steel Sheets per mit true bends, tight joints and neat seams, even in. forming difficult angles ' and Bhapes when working in close and confining places. U.S.S. Galvanized Steel Sheets are produced in a wide variety of sizes and forms. Our engineers are specialists in their use and will gladly assist you in their application. Other U.S.S. Steels famous for service U.S.S. STAINLESS STEEL is ideal for use in chemical plants, laboratories, and other places where highly corrosive at mospheres would spell early destruction for less durable materials. Its high re sistance to corrosive attack, great strength, ease of cleaning and high re sistance to extremes of temperature are definite money-saving advantages. U.S.S. COPPER STEEL--coated or uncoated, insures increased resistance to corrosion, and increases life under all conditions of atmospheric exposure. U.S.S. GALVANIZED PAINTBOND STEEL--for ductwork requiring imme diate painting without preliminary treatment or weathering. Paint will not flake. Bonderized surface prevents dete riorating action between paint and gal vanized coating. A similar sheet, U.S.S. DULKOTE, is available in the South and the West. 1425
