Air System Equipment Air rater* CE23& Vortox Company Claremont, California, Panel Air Filters for all Industrial Applications Vortox Panel Air Filters are of the cleanable, impingement, viscous-coated type with exceptionally low air flow resistance. They are made for use in air conditioning ventilation, range canopies, engine intakes, and general air filtration. EFFICIENCY. Vortox Panel Air Filtera are efficient at both high and low air flows. Consequently to reduce costs of the original installation or to save space, fewer Vortox Filters may be used at higher air velocities. To assure a longer service life, more Vortox Filters may be used at lower velocities. In either case Vortox Panel Air Filters provide better cleaning at lower cost. Filter with Frame OPERATION. Numerous changes in direction of dust laden air cause the dust particles to impinge on the adhe sive viscous-coated surfaces of the filter Vortox Type VR Panel Air Filter illus trated above is the type used on engine intakes and in car bodies of diesel loco motives. It is constructed to withstand the severe usage of locomotive service. It has exceptional characteristics as in all types of Vortox Panel Air Filters. FILTER ELEMENT. Fabricated of elastic units of fine steel wire positively interlocked to provide a permanent filter, the element offers many advan tages: (1) In a 2 in. x 20 in. panel there are from 9300 to over 15,000 feet of fine steel wire, depending upon the type. (2) Even distribution of filaments ex poses innumerable viscous-coated sur faces to the air stream, thus obtaining the most effective cleaning for space occupied. (3) Proper spacing of fila ments prevents clogging and assures maximum dust removal efficiency. (4) Structural strength and permanent re silience combine to withstand "packing" effect of vibration and pulsation. element. Coarser particles collect near the entrance, while finer particles pene trate to a greater depth. As the entrance becomes saturated the cleaning action takes place deeper in the filter and the restriction is increased slightly. In creased restriction in certain sections of the filter diverts the air to cleaner sec tions, thus distributing the dust load' for a higher over all efficiency and a greater total dust-holding capacity. EASY TO CLEAN. All dust and lint are easily and completely flushed from the filter by water or steam sprays.
