Manufacturers of Wing Featherweight Unit Heaters, Wing Turbine and Motor Driven Blowers, Wing-Scruplex Fans and Exhausters WING FEATHERWEIGHT UNIT HEATERS The Wing Featherweight Unit Heater, expressly designed for overhead installation, makes available for any industrial building a heating system that leaves all floor and'wall space absolutely unobstructed. The success of this system has been proven by the satisfactory operation of several hundred units in industrial buildings of every kind and description. The installation of Wing Featherweight Unit Heaters is extremely simple, due to their light weight and small dimensions. For instance, a unit equal in heating effect to 12,000 sq. ft. of direct radiation, weighs only 332 pounds. A few advantages attending the installation of Wing Featherweight Unit Heaters may be briefly summarized as follows: . The heated air from the units, located at or near the ceiling or roof, is delivered directly downward toward the floor, heating the working level first. Chilled areas, caused by opening of doors, are almost instantly brought back to normal temperature by this downward method of heating. Since the air recirculated by the heaters is taken from the upper spaces and delivered to the lower levels, it is evident that an active circulation of air from the ceiling to the floor is continuously maintained and that, therefore, excessive heat is not allowed to accumulate in the upper spaces, as is the case with any system of heating that allows the heat to rise to the ceiling immediately, as it does in the case of direct radiation. . The steam and return lines are carried entirely overhead, eliminating costly pipe trenches which are necessary when radiation is placed at or near the floor. All vertical type heaters are furnished with ball bearing motors that do not require attention more than once a heating season. METHODS OF INSTALLATION The cuts show three different methods of installation, the units in each case being located well above the head line, out of the way. The third illustration shows the high ceiling type heater installed thirty feet from the floor above a traveling crane. The column of heated air leaves the heater with sufficient velocity to strike the floor with considerable force from this point, but by. the aid of adjustable diffusers the column is divided and directed so that no objec tionable velocity is felt at the head line. The best and most economical installation of Wing Featherweight Unit Heaters is when they are placed close to the roof or ceiling.

Capacities from 950 C. F. M. to 33,000 C. F. M. Up to 25 in. diameter, propellers are made of cast aluminum alloy while the larger sizes are of pressed steel. Wing-Scruplex Fan WING TYPE E M MOTOR DRIVEN BLOWER Wing motor-driven Blowers are installed in heating boilers so that low cost Buckwheat coal can be burned with great savings in fuel bills and with better heating results. They are also used in industrial plants where motor drive is preferred to turbine drive. The'Wing E M Blower is a simple compact unit of motor, fan, and casing, of the same general design as the Wing Turbine Blower, the first individual forced draft fan blower ever built Where Wing units cannot be set directly into the brick base of the boiler, they are equipped with feet or base and mounted to the floor with the discharge connected to the ashpit by a short sheet metal duct. Motors are fully enclosed and Ask for Bulletin 36 dustproof. Because of this feature they stand up for years in the dusty atmosphere of boiler rooms without repair. Another feature of prime im portance is variable speed control; this permits of regulation without the use of dampers and saves power. Wing Blowers are cutting down fuel bills in hundreds of schools, apartment houses, lofts, hotels, churches and institutions throughout " the country. Booklet 36 describes Wing motor-driven units. Information on Wing turbine- TyPe E M Blower driven units in Bulletin 77. Typical installation in a New York, apartment house where the use ofBuckwheat coal in place of domestic sizes is satring the owner a large part of his previous fuel bill. In the right foreground is shown an E M Blower connecting directly into the rear end of a cast-iron hot water boiler; the E M Blower in the background serves the two steam heating boilers. Note how com pact this installation is--a characteristic of Wing E M Blower layouts. 411
