, Air System Equipment Ait Filters and Cleaners American AirJ^ilterCompany Inc. 673 Central Avenue, Louisville 8, Ky. In Canada: Darling Brothers, Ltd., Montreal, Quebec AAE PRODUCTS: The American Air Filter Company, Inc. manufactures a complete line of Air Filtering Equipment including Electronic Air Filters, Automatic SelfCleaning Filters, Viscous Unit Filters, and Dry Process Filters to be used for the removal of dust, soot, smoke, dirt, bacteria and other foreign matter from the air. Because air filtration has proved to be the economical, practical and efficient method of cleaning the air, the modern air filter is now considered an absolute neces sity in building ventilation or air con ditioning, in the maintenance of health and personal efficiency, protection of interiors and furnishings and valuable merchandise and equipment. Shown here are but a few American Air Filter products in most general use. The American Air Filter Company is recognized as an authority on dust problems and their satisfactory solution. Products offered embody the knowledge accumulated from twenty-six years of intensive research devoted exclusively to the study of dust problems and the development of air clean ing apparatus; the experience gained from designing, building and applying thous ands of air filters; are backed by ample technical and financial resources; and may be relied upon as the most modem equip ment in their field of service. THREE TYPES OF ELECTRONIC AIR FILTERS For more than ten years, research and experimentation with electronic air filtra tion have been in progress by AAF engi neers. Today's complete line includes the self cleaning Electro-Matic introduced in 1939, the washable Electro-Cell with re movable collector plates, and the Electro- Airmat with the replaceable Airmat paper medium. Here for the first time is high efficiency air cleaning in three types of electronic filters to meet any requirements for super clean air. Electro-Matic Self-Cleaning Elec tronic Filter--The Electro-Matic filter is a self cleaning electric precipitator combining the most advanced principles of electronic air cleaning with notable improvements in construction details and method of operation. The self-cleaning feature is an exclusive advantage of the Electro-Matic filter. It eliminates the necessity of shutting down the filter for manual cleaning, minimizes the need for personal atten tion and permits continuous high-efficiency operation. It also allows the ElectroMatic filter to be built in standardized self-contained sections, easy to install and with all exposed parts of the filter casing electrically grounded for the protection of operating personnel.

Air System Equipment Air Filters and Cleaners Electro-Cell Electronic Filter--Incorporates all of the new developments of major importance in elec tronic air filtration using col lector plates. Installation has been simplified, performance improved and maintenance advantages provided. Built in vertical sections of two widths--2 ft and 3 ft over-all. Collector plate assemblies are removable; ionizers are hinged and extend the full height of the sections, preventing cur rent loss. A choice of wash ing collector plate assemblies while in place, or removing assemblies for individual cleaning. Installation is sim plified because filter is built in vertical sections rather than assembled of small units. Parts to be lifted and aligned are light in weight and elec trical connections simplified. Write for Bulletin No. 252. Electro-Airmat Elec tronic Filter--The applica tion of an electrostatic charge to a dielectric filtering ma terial is an exclusive AAF research development which began early in 1934. Airmat paper is composed of a num ber of plys of porous tissue like cellulose sheets. When electrically charged the plys tend to separate and each individual fibre becomes a collecting electrode which at tracts and holds the dust and smoke particles. Ease and convenience of maintenance is a desired advantage of the Electro-Airmat. Requires neither water nor sewer con nections for cleaning, nor spraying with oil to maintain its efficiency. When Airmat paper has accumulated its Electro-A IRMA T Filler American Multi-Duty Self-Cleaning Filter dust load it is removed and replaced with clean material by means of a mechanical loader. In case of power fail ure, filter media provides best mechanical air filtration known. Send for Bulletin No. 253. American Multi-Duty Automatic Filter provides outstanding features of per formance and design and will accomodate either armored screen panels or die stamped louver panels available in three types. Offers advan tage of uniformly constant air supply, fixed operating resist ance and automatic operation. Ideal for ventilation and air conditioning service. Avail able in any size or capacity.
