190 Air System Equipment air fuu>> YORTOX 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 resistance to airflow. They are made for use in air conditioning ventilation, range canopies, engine intakes, and general air filtration. EFFICIENCY. Vortox Panel Air Filters are efficient at both high and low airflows. 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 The Vortox Type VN Panel Air Filter illustrated above is the type used in air conditioning units and for general air filtration. The Vortox Type VG Panel Air Filter, similar in ap pearance but of heavier construction, is the type used as a combination filter and flame arrestor in kitchen range canopies. OPERATION. Numerous changes in direction of dust laden air cause the dust particles to impinge on the adhesive viscous-coated surfaces of the filter element. Coarser particles collect near the entrance, while finer FILTER ELEMENT. Fabricated of elastic units of fine steel wire positively interlocked to provide a permanent filter, the element offers many advantages': (ij In a 2 in. x 20 in. panel there are from 9,300 to over 15,000 feet of fine steel wire, depending upon the type. (2) Even distribution of filaments exposes innumerable viscous-coated surfaces to the air stream, thus obtain ing the most effective cleaning for space occupied. (3) Proper spacing of filaments prevents clogging and as sures m^rimum dust removal efficiency. (4) Structural strength and permanent resilience combine to with stand "packing" effect of vibration and servicing. particles penetrate to a greater depth. As the entrance becomes saturated, the cleaning action takes place deeper in the filter and the restriction is increased slightly. Increased restriction in certain sections of the filter diverts the air to cleaner sections, thus distribut ing 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.
