Fans and Ventilating Equipment L. J. Wing Mfg. Co. Branch Offices In Principal Cities 59 SeventhAvenUe, New York Phone: CHelsea-3 0027-0030 Factory: NEWARK, N. J. Wing Featherweight Unit Heaters and Process Heating Units; Utility Unit Heaters; Wing Scruplex Safety Ventilating Fans, Fog Eliminators and Exhausters; Wing Forced Draft Blowers, Turbine or Motor-Driven; Steam Turbines; Man-Coolers. THE original and exclusive features of Wing Feather Standard Discharge. Outlets for. Type HC weight Unit Heater design-- their light weight, the vertical downward discharge of the heat ed air, and multiple discharge outlets which step up the velocity of the air leaving the heater---are directly responsible for definite economies in the actual cost of industrial plant heating and in the cost of the equipment itself. TYPE LC UNIT Cross-Section showing location of motor and fan. Used in buildings having low roofs . or ceilings TYPE HO UNIT Complete coverage accomplished with any New Wing Featherfin Heating Element--(Tested to 1000 lbs. Pressure). Extremely light in weight. By simple variations of the heating surface any desired final air temperature may be ob tained with any given steam pressure. Standardized for steam pressures of 5, 40, 70, 100 and 130 lbs. all producing the same low final air temperatures. Fin and tube extended surface type. Hairpin or return bend design. Headers of steel, tubu lar design. Tubes secured to headers by steam-tight compres sion union. Easily removed and replaced in case of damage. Condensed Table of Engineering Data Type H. C.

Fans and Ventilating Equipment ^'V' '-VA*' y'VV' ''/VV' Method of Heater Installation-First diagram shows a Type HC Unit installed above a traveling crane, the heater arranged so that the lower left portion of the building is also heated. Second diagram shows a plan view illustrating the general distribution and diffusion of heated air from Wing Heaters. The third pictures a typical multistory building heated with type LC Wing Units. The best and most economical installation of Wing Featherweight Unit Heaters is when they are placed close to roof or ceiling. Wing Utility Unit Heater Wing Featherfin Process. Heating Units I I 1 II A general purpose heater. Delivers heated air in one general direction. With vane diffusers and safety guard for fan. Capacity data same as Type HC on preceeding page. For manufacturing processes such as drying, ageing, etc., requiring the recirculation of the heated air. Motor or turbine located, outside air current. Wing-Scruplex Fog Eliminators supply tempered fresh air to completely de-fog any building or room where steam, ?fog or fumes are liberated in manufacturing processes. Wing-Scruplex Safety Ventilating Fans An integral guard of strong steel rings welded to the frame features every model of the WingScruplex Safety Ventilating Fan. This guard removes the ever-present danger which exists . whenever fans are in an exposed location, and does not reduce fan efficiency. The high volumetric efficiency of Wing- Scruplex SaftHfy Fans is due to their true screw propeller design which . moves the air forward in straight lines without eddy. Motor is fully enclosed, easily accessible and generously proportioned. Can also be supplied with pulley or turbine drive. Wing-Scruplex Safety Fans are built in the following sizes: 10, 13, 17, 22, 25, 30, 36, 42, 48, 54 and 60 in.--capacities from 950 c.f.m. to 33,000 c.f.m. Up to 25 in. dia. propellers are made of cast-aluminum--larger sizes of pressed steel. 641'
