Wing Blowers for Forced Draft Wing motor-driven Type EM Blowers are chosen for forced draft for heating boilers of all sizes because they maintain the same high standards which have made the Wing Turbine Blower standard forced draft equipment for pressure boilers for 25 years. The installation of a Wing Unit makes possible the use of Buckwheat coal and other inexpensive fuels with great savings in.fuel costs, which usually pay for the blower in the first year of operation. These blowers are'of the propeller type fan construction. They affords large air passages and- low air velocities, re sulting in quiet operation and even fires. Wing EM. Blower Wing Blowers are con-, trolled byspieed regulation, conveniently operated from the front of the boiler. Totally enclosed' motors keep out the dust and dirt of the boiler room; insuring many years of service without' repair. Automatically controlled, they make the fireman's work easier. There' is also the Wing Intensi-Fire System for burning Buckwheat coal .in the home. Askfor Bulletin No. 46 describing Wing EM Units, and Bulletin No. 87 describing Turbine Blowers. The Wing Blower in foreground supplies forced draft to hot water supply heater; while blower in .background serves two return tubular heating boilers 654 Furnaces, Warm Air Langenberg Manufacturing Co. 4549 No. Euclid Ave. St. Louis, Mo.

The above data in connection with the . Standard Code, published as a part of the Chapter on Gravity Warm Air Heating, will enable the Architect, Engineer or Con tractor to specify the correct size Front Rank furnace for any project. Any Front Rank furnace installed by an authorized dealer according to the Standard Code is guaranteed to maintain. an average temperature of 70 deg. in zero weather. The Front Rank is such a system-- equipped with fan, vapor supply, air filters, etc. Stratification is reduced by a positive air movement thus providing a higher degree of comfort than is ordinarily pos sible. Air conditions are under control. Wind pressures are overcome. The system occupies no usable space in the parts of the building to be heated. In small buildings the Standard Code is followed. In large buildings modern engineering principles are used in accu rately computing heat losses and estimat ing required capacities. Each system is designed especially for the building in which it is to be erected. We have specialized in good Warm Air Heating since 1888. 655 ! I.
