Manufacturers of Wing Featherweight Unit Heaters, Wing Turbine and Motor Driven Blowers, Wing-Scruplex Fans and Exhausters Win* Featherweight Unit Heaters--The outstanding features of Wing Featherweight Unit Heaters are their extreme light weight (about 1/10 that of the old style) and small dimensions, combined with the tact that the driving motors are direct connected (no belts) and are out of the path of the heated air. Horizontal Type These features open a much broader field of application for this system of heating--in effect the hot-blast sys tem--which is generally accepted by engineers and architects as the best system for industrial plants and other buildings of large open areas such as garages, armories, etc. The features emphasized above make possible the suspending of the units from the ceiling or roof of any building old or new, without neces sitating additional strengthening of the structure. It is not necessary to place the units on the ground where they will occupy space valuable for other purposes, and in addition to this, all steam and return lines may be carried overhead, out of the way, eliminating the necessity of pipe trenches. Wing Featherweight Unit Heaters are made in four different designs; Vertical High ceiling--Vertical Low ceiling--Horizontal and Floor type, the latter for use where the roof is very high and there are no convenient columns from which to support the units overhead. Two of these designs are shown also the method of installation. Low Ceiling Type Saves Valuable Floor Space DATA FOR WING FEATHERWEIGHT UNIT HEATERS Size Unit Ax A B C D Air Motor C. F. M. H. P.

Fans and Ventilating Equipment WING FORCED DRAFT BLOWERS Type E-M Motor Driven The Wing motor-driven units come in various sizes to fit all kinds and types of boilers. Installation is usually made in side ashpit walls to eliminate ducts and save space. For control purposes hand regulating rheostats are employed on single phase and direct current motors. For polyphase current dampers are used. Automatic control can be supplied if de sired. Wing E-M Units in service have proven highly efficient in overcoming deficiencies in draft due to low stacks, poor weather conditions, etc., and they are admirably suited for the burning of the finer grades of coal such as Rice, Barley, Screenings, Culm and the like. Write for Bulletin 16 for further details. In high pressure plants the Wing Turbine blower has become standard equipment for serving the forced draft to stokered or hand-fired furnaces. The units are com pact and easily installed and have air deliveries up to 20,000 cu. ft. per min. with static pressure up to 8 in. The exhaust steam from the turbine is clean and can be used for feed water heating, process work, etc., where the back pressures run as high as 8-10 lb. Hand or automatic con trol can be effected. For further details write for Bulletin 57. Type REV Turbine Driven WING-SCRUPLEX EXHAUSTERS The Wing-Scruplex Exhauster consists of a highly efficient screw-propeller fan, combined with a casing of convenient design with the motor on^he outside where it will keep clean and cool, and be easy of access. Because of these features it is used for duct work where the r ir Wing-Scruplex Exhauster resistance is low in stead of propeller fans with motors directly attached, where here tofore to obtain these features it has been necessary to use encased fans of the multivane type. Being designed in the form of an elbow, it fits very well into any run of duct. It's rectangular frame greatly simplifies installation. Exhauster Makes Hotel Kitchen Comfortable Place to Work Wing-Scruplex Fan WING-SCRUPLEX FANS Sizes including 25" in diameter are furnished with propellers of cast aluminum alloy. Larger than this are steel, pressed to the same form. Note particularly-the true screw design of the. propeller. Built in sizes 10", 13", 17", 22", 25", 30", 36", 42", 48", . 54", arid 60".
