L. J. Wing Mjg. Co. Air Conditioning Unit Heaters ZZET Design No. 1 Design No. l-HV Design No. S Type "HC" Fixed Discharge Design No. 7 WING DaiSU N- * FIXED DISCHARGE UNIT HEATERS The first light-weight, ceiling-suspended, unit heater. Eight different designs of outlets meet the requirements of every type, size and height of building or oc cupancy. Located near ceiling or roof, the accumulation of hot air in the upper spaces, with the accompanying costly waste of heat, is prevented. They project the air, comfoftably warmed, downward to the working area. Bulletin HRS. DOOR HEATERS GARAGE HEATERS WING developed this vertical conedischarge heater in 1921 and today it is still applicable for heating the inrush of cold air at large doorways and for garage heating. Often cuts heating costs in half. Bulletin HR-4. FOR LOW CEILINGS In this type of WING Unit Heater the' position of fan and motor are re versed to meet con ditions of ceiling or roof height, form Type "LC" and shape of building, coverage, etc. Bulletin HR-4. WING UTILITY UNIT HEATERS A lightweight suspended unit heater for delivering heated air in one general direction. Has the same powerful fan and rugged heating element as WING Featherweight Unit Heat ers. This is the latest re finement of the original horizontal light weight heater which was developed by WING. Bulletin HR-4. Design No. 6 Design No. 8 FEATHERFIN HEATER SECTIONS For heating or cooling air for any purpose by steam, hot or cold water or refrigerant. The heating element is extremely light and, for equal heat trans fer, offere little resistance to air flow. Available for any desired final air tem perature. Bulletin HS-B. VARIABLE TEMPERATURE SECTIONS Invaluable in supply ing fresh air for space heating or process work. Close control of the de livered air temperature is obtained without danger of freezing. Manual or automatic control.

Air Quality Control for Air Condi tioning--Airkem Chlorophyll Air Fresh ener reduces odors and provides a fresh indoor air quality. Manufactured under U. S. Patent 2,326,672, Airkem contains activated chlorophyll and is especially suited to industrial and commercial ap plications. The efficacy of Airkem in producing a fresh indoor air quality has been demon strated by its use in theaters, department stores, industrial plants, banks, hotels, restaurants, offices and in the most exact ing of all fields--hospitals. In addition, Airkem permits reduction of the fresh air intake in air conditioning systems with corresponding reductions in both summer and winter load, and savings in fuel, water and electric power. ..Easily Added to Systems--It is easy to engineer Airkem into new systems or . add to existing air conditioning or venti lating systems, either large central systems or the smaller packaged units. The Airkem Evapatrol unit consists of a small vaporizing cartridge enclosed in an attractive casing, an Airkem reservoir with pump and an Airkem regulator.The vaporizing unit can be installed^ directly on the side of the fan section of a packaged type unit or on the fan section of the plenum chamber of any central system. The suction of blower in either case draws air through the cartridge which is saturated with Airkem. The satura tion of the cartridge is maintained by , means of a solenoid operated pump which is mounted directly on the Airkem reservoir, and pumps the Airkem to the distributor in the vaporizing unit. The operation of the pump is controlled, by the regulator which permits adjusting the amount of Airkem by timing the pump strokes at the required intervals. Both the Airkem regulator and reservoir can be installed at remote locations. 1003
