Air System Equipment Air Filters and Cleaners Supreme Air Filter Company 126 West 21st Street, New York li, N. Y. SUPREME WASHABLE DRY TYPE AIR FILTERS AUTOMATIC OR MANUAL CLEANING Supreme Air Filters are made of a spun glass filter media, annealed under a patented process, and covered with a galvanized or copper wire mesh 25*06, encased in a gal* vanized or copper frame. Supreme Filters offer a low resistance to the free flow of air, are light in weight and easy to handle. All cells are equipped with handles and interchangeable in the same bank. Supreme Filters are made in flat and saw tooth types: The flat filter is encased in a in. frame, for convenience in ordering and lower cost production. The sawtooth type is corrugated the depth of the cell frame thereby increasing the filtering surface in a given area. The spun glass in Supreme Filters is FIRE, Supreme Air Filter (Before and after cleaning) ROT and VERMIN proof and not attacked by any chemical other than hydro-fluoric acid; it is approved by the Board of Fire Underwriters. The important factor in rating a filter is generally not the removal of a certain per cent of dust by weight but rather the effectiveness for taking out certain objectionable con stituents, which may be either the finest particles present or the coarser ones within a certain range. The lower number per cent of dust particles in buildings and out-of-doors occur just after air washing by rain or snow storm, and the greatest number in busy streets on dry days. Supreme Filters can be washed in hot or cold water, adding a little soap powder or solvent, and spraying with not over 25 lb. water pressure. New mats can be supplied for all Supreme cell frames where mats become worn put or defaced, thereby saving the cost of a new frame.
