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 Featherweight unit heaters are their extreme light weight (about one-tenth that of the old style) and small dimen sions, 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--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 emphasised make possible suspending the units from ceiling or roof of any building, old or new. without necessitating additional strengthen ing of the structure; and the overhead installation makes it possible to run all steam and return lines overhead out of the way. Wing Featherweight unit heaters heat 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. Horizontal Type 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 con siderable 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 close to the roof or ceiling.

J. Wing Mfg. Co. Fans and Ventilating Equipment WING-SCRUPLEX EXHAUSTERS Wing Scruplex Exhausters consist of the highly efficient "screw propeller" fan and cased in appro priate manner with a motor on the outside where it is clean, cool and easy of access. They are used in duct work where the resistance is low and being de signed in the form of an elbow fit snugly in any line. The accompanying diagrams show the methods of installation.

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 sixes are of pressed steel' Wing-Scruplex Fan WING FORCED DRAFT BLOWERS The Wing Type E M blower makes the ideal forced draft for heating bodere. This small, compact propeller fan outfit is an integral unit, ready to mstalL No belting or coupling; the fan is right on the motor shfcft. 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 small 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. Type REV. Turbine 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 nigh as 1000 h. p. Either manual or automatic operation may be had. Ask for Bulletin 67. 369 Type E M Motor Driven
