Manufacturers of Wing Featherweight Unit Heaters, .Wing Turbine and Motor Driven Blowers, Wing-Scruplex Fans, Exhausters, Fog Eliminators 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 dimen sions. For instance, a unit equal in heating effect to 12,000 sq. ft. of direct radiation, weighs only 332 lbs. A few advan tages 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. 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.

J. Wing Mfg. Co. Fans and Ventilating Equipment Methods of Installation The drawings below show typical high ceiling and low ceiling installations, together with a plan view illustrating the general distribution and diffu sion of the heated air from the unit heaters. The first illustration shows the high ceiling type heater installed 30 or more feet from the floor, above the travelling crane, the heater arranged so that the left lower portion of the building is also heated. The third illustration shows a typical multi-story building heated with Wing low-ceiling type Unit heaters. 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 Five Wing Heaters in this Shop 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.

Wing Fog Eliminators Wing Fog Eliminators supply tempered fresh air to completely de-fog dyehouses, bottling, preserving and pasteurizing plants, paper mills, and in general any building or room where steam, fog or fumes are liberated in manufacturing processes. Wino-ScrwpUx Exhauster Wing-Scruplex Exhausters Wing Scruplex Exhausters consist of the highly efficient "screw propeller" fan encased 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 diagrams at top of next page show the methods of installation.
