Air Conditioning Unit neater. Factories: NEWARK, N. J. L. J. Wing Mfg. Co. Canadian Factory: 59 Seventh Avenue, New York 11, N. Y. MONTREAL Branch Offices in Principal Cities WING REVOLVING UNIT HEATERS This innovation in the method of dis tributing heat produces a sensation in heating comfort never before attained--a sensation of fresh, live, invigorating air. The fact that the outlets revolve assures uniform and thorough distribution of com fortably warmed air throughout the entire working area, without drafts, hot spots or cold spots. Such an unprecedented high efficiency in distributing heat is the result of nearly 20 years of constant study by Wing engi neers to improve on the Floodlight System of heating pioneered by WING in 1921. This method projects the heated air verti cally downward by means of light-weight, ceiling-suspended unit heaters. It has needed only this latest refinement of slowly revolving discharge outlets to bring that method to perfection. The WING Revolving Discharge type supplements the WING line of standard fixed discharge outlets, illustrated and described on the following page. Bulletin HR-4. The latest type of WING Unit Heater-- with Revolving Discharge Outlets--is just as great a contribution to the art of industrial heating as was the Ceiling-Suspended Unit Heater, an nounced by WING in 1921. The area covered by a WING Revolving Unit Heater is slowly swept by the heated air discharged by the outlets which move through an arc of 360 deg. covering every direction of the com pass successively. By maintaining an active, constant circu lation of air through out an industrial plant at all times, a new sensation of refreshing, invigorating comfort to workers is produced. Elevation 1000 L. J. Wing Mfg. Co. Air Conditioning Unit Heaters Fans and Blowers WINGFOIL SAFETY VENTILATING FANS An axial flow fan that will deliver air against static pres sure, quietly and efficiently. Moves the air forward in straight lines with minimum eddy. Capacities to 100,000 cfm. Bul letin F-9. WING FEATHERFIN PROCESS HEATING UNITS For man ufactur ing processes such as drying, aging, etc., re quiring the recirculation of the heated air. Motor or turbine located outside air cur rent. Bulletin P-2. WINGFOIL DUCT FANS For economically moving air wherever ducts are used. It combines the efficient WINGFOIL AXIAL FLOW Fan with a housing which places the motor entirely outside the air duct. Motor and drive remain cool and clean and are easily The powerful WINGFOIL Fan delivers high air volume with low power consumption against any pressures for which duct systems should be designed. V-belt or direct drive. Light, compact and easy to install. Bulletin F-9. WING SYSTEM OF CONTROLLED COMBUSTION For low pressure heating boilers and small power boilers. Increases capacity and permits use of lowest cost fuel. Includes Type EM Blower equipped with fully enclosed dustproof motor with speed regulating rheostat and automatic control. Eliminates necessity of frequent firing, allowing intervals as great as 24 hours even in zero weather. Bulletin M-96. WING TURBINE-DRIVEN BLOWERS - Applied to hand, stoker, oil or pulverized fuel fired boilers, increase boiler capacity, maintain constant steam pressure and permit com plete combus tion of low-cost fuels. The ex haust steam, free from oil, can be used for heating or pro cesses. Bulletin T-98. WING DRAFT INDUCERS Installed in breeching or flue, or on chimney top; provide positive, exact draft regardless of weather conditions or inade quate chimney or breechingcon struction. Suit able for coal, oil, or gas-fired boil ers; industrial furnaces and kilns. Bulletin Chimney-Top Installation 1-10. Installation of Wing System of Controlled Combustion in a large school WING MOTOR-DRIVEN BLOWERS Type COM for static pres sures over 5 in. and volumes up to 35,000 cfm. Type EMD for moderate static pressures up to 5 in. Both blow Type COM ers have fully- enclosed dustproof constant speed motor and built-in adjustable control vanes. Type COM has double-staged axial flow fan; Type EMD, single stage fan. Extremely com pact; discharge can be vertical, horizontal or in clined. Bulletin COS. Type EMD 1001
