Manufacturers of Wing Featherweight Unit Heaters, Wing Turbine and Motor Driven Blowers, Wing-Scruplex Fans and Exhausters Wing Featherweight Unit Heaters The outstanding features of Wing Feather weight unit heaters are their extreme light weight (about one-tenth that of the old style) and small dimensions, combined with the fact that driving motors are direct connected (no belts) and are out of the path of heated air. These features open a much broader' field of application for this system of heating--in effect the hot blast system--which is generally accepted by engineers and architects as the best system for industrial plants and other buildings of large open areas such as parages, armor ies. etc. The features emphasized make possible suspending the units from ceiling or roof of any Horizontal Type building, old or new, without necessitating additional strengthening of the structure; and the overhead installation makes it possible Vertical High Ceiling Heater to run all steam and return lines overhead out of the way. Wing Featherweight unit heaters beat the floor or working level first. Being placed near the roof or ceiling, they withdraw the heated air which tends to accumulate there and return it to the working level where it is needed. Con siderable economy is effected by reducing the temperature directly under the roof where heat transmission is always the greatest. Wing Featherweight unit heaters are made in four different designs: vertical, high ceiling, vertical medium ceiling, vertical low ceiling, and horizontal. mtid I .3S0S 7E 7FJ7K LJ1 * Methods of Installation The above cut3 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 travelling crane. The .column of heated air leaves the heater with sufficient velocity to 6trike the floor with considerable force from this point, but by the aid of adjustable diffusers the column is divided and directed so that no objectionable velocity is felt at the head line. ---- The best and most economical installation of Wing Featherweight unit heaters is when they are placed dose to the roof or ceiling.

Fans and Ventilating Equipment WING FORCED DRAFT BLOWERS The Wing Type E M blower makes the ideal forced draft for heating boilers. This small, compact propeller fan outfit is an integral unit, ready to install- No belting or coupling; the fan is right on the motor shaft. Where the base of the boiler is not high enough to accommo date the fan casing, the blower is provided with feet for mounting, placed a short distance away and connected to the boiler by means of a piece of duct. E M units are furnished either in D. C., polyphase or single phase with speed regulation; or with squirrel cage motors and damper regulation. Ask for Bulletin 26. Type B M Motor Driven The Wing Turbine Blower, while long con sidered standard equip ment for supplying forced draft to handfired boilers, has in more recent years be come widely used for stokered boilers as well, a single blower deliver ing enough air to develop as high as 1000 b. p. fether manual or automatic operation may be had. Ask for Bulletin 67. 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 the outside, where it wijl keep clean and cool andbe easy of access. Because of these features it is used for duct work, where the resistance is low, instead of propeller fans with motors directly attached. Being designed in the form of an elbow, it fits very well into any run of duct. Its rectangular frame greatly simplifies installation as mil be seen from the following diagrams. -.. ..
