File No. 30 G-l. 920 Air Conditioning, Water Treatment Oakite Products, Inc. 22 Thames Street, New York, N. Y. Branch Offices and Representatives in All Principal Cities of the U. S. OAKITE AIREFINER Established 1909 A new material that prevents corrosion, controls bacteria growth, prevents slime and algae ac cumulations. Materials also available for rust and scale removal, cleaning and deodorizing. Bacteria, Slime and Algae Control Does your air conditioning equipment use a recirculating water supply? Increase the efficiency of it by preventing the growth of bacteria, slime and algae in the circulating water. This is accomplished easily, inexpensively with a new develop ment of the Oakite Research Laboratories, known as Oakite Airefiner. It is a dry, non-volatile white powder, completely soluble in water to provide safe, odorless, non-toxic solutions. Used in extremely low concentrations, one pound to 300 to 500 gal of water, this powerful bacteri cidal agent controls the growth of bacteria, slime and algae. Equipment is kept free of these accumulations, and from the un pleasant odors which they create. Preventing Corrosion Oakite Airefiner has been specially com pounded to also incorporate sufficient alkalinity to counteract the development of acidity in the water due to extraction of sulphur dioxide and carbon dioxide gases from the air. If not prevented, this acid condition causes rapid corrosion of elim inators, air wash chambers and other metallic surfaces with which the untreated water comes in contact. Cleaning and Deodorizing Users of Oakite Airefiner enjoy a number of other definite advantages. Increased wetting power of water con taining Oakite Airefiner has resulted in actual removal of more dirt from the washed air. Eliminators, spray heads and water feed lines are kept free of scale and similar corrosion as well as of bacterial accumulations, slime and algae. The washed air is freed of practically all the matter which is responsible for objection able odors in re-used air. Cleaning Filter Screens Where filters are of the re-usable and washable type, Oakite cleaning methods provide a quick, safe, complete removal of the accumulated dust and dirt. No injury is done to the glass, metallic or similar material which comprises the filtering surface. Rust and Scale Removal Removal of rust and scale from feed water pipes, water cooling chambers or on other metallic surfaces can be accomp lished safely and economically with Oakite Compound No. 32. -This is an acidic material especially prepared to provide absolutely uniform scale and rust dis solving action without having any harmful effect on the sound underlying metal. Specific recommendations on work of this type will be sent upon request. Nation-Wide Service Oakite materials are supplied through a nation-wide group of service representa tives who are thoroughly experienced in their application. Users are thus assured of employing the materials in the way to get the full bene fits they provide.
