Write for Bulletins mentioned below, or call the "Buffalo" Engineering Representative in your nearest principal city. "Buf falo", publisher of "FAN ENGINEERING", is ready to work with you on any air problem, you may have. TYPE "BL" VENTILATING FANS. These non-overloading centrifugal fans are widely used in large ventilating and air conditioning systems where quiet operation and high efficiency are desirable. Performance is completely stable, from free air delivery to shutoff. Smooth bell-shaped inlet and duct collars with "Buffalo" directional inlet vanes, minimize entry turbu lence. The rotor has a curved shroud matching the inlet bell, as well as double backward curved blades for smooth, quiet air flow through the streamlined, full-curvature housing. Capaci ties from 1000 to 500,000 cfm. Wide choice of arrangements. Write for BULLETIN F-101. INDUSTRIAL EXHAUSTERS; All-welded steel plate construc tion in these heavy-duty fans means smooth rivet-free interior surfaces for minimum friction. Available with interchangeable "AW" Air Wheels for airborne dusts, gases, fumes, or with "MW" Material Wheels for grit, sawdust, grain, stringy ma terials. Available with heat slingers to handle gases up to 1000 F. in induced draft and other high temperature applications. Write for BULLETIN 3576. AXIAL FLOW VENTILATING FANS. For light-duty (up to 3 in. s.p.) ventilation, exhausting, system boosting, draft and circulation applications, these lightweight fans fit into straight duct runs, taking up no more room than a section of round duct. Extremely quiet, efficient and non-overloading. Avail able in tubeaxial (without directional vanes) or vane-axial (with directional vanes) models, with direct connected motorin-housing or with Vee-belt drive and motor out of air steam. Models for high or low temperatures, non-sparking and/or corrosion resistant construction. Write for BULLETIN S5SS-EF. AIR CLEANING EQUIPMENT. "Buffalo" builds all types of units from Air Washers like the one shown for cleaning, humid ity control, heating and cooling to highly specialized units for abating effluent nuisances in the chemical and process indus tries. More than a half-century of experience in this field is at your service, as well as our complete manufacturing facilities. Write for Bulletins on the industry-proved "Buffalo" equip ment to solve any air cleaning or processing problem you may have. PC CABINETS (1).

Write for BULLETIN S1S7-E. Also, a wide selection of heating and ventilating units, with or without filtered intake and by-pass dampers, suspended and floor models for large areas. 1382 Air System Equipment Alan E. Burden Co., Inc. Manufacturer of Propeller Type Fan Blades 1940-50 Pontius Ave., Los Angeles 25, Calif. For Air Conditioning Refrigerating and Heating Applications All Burden Fan blades are individually inspected after leaving the production line for bore size with "go and no-go" gauges, to a tolerance of plus or minus one J^oooth of an inch. Each fan blade is individually gauged on a special machine for contour and alignment, then statically and dynamically balanced with Mechanical, Audio Vibration Equipment. A modern, completely equipped laboratory makes possible exhaustive performance tests. Expert engineering counsel is available for requirements involving unusual applications. A laboratory at the factory is equipped for both routine and special testing when necessary. BURDEN 3 BLADE FANS. Furnished clockwise and counter-clockwise.
