Sixty-Sixth Street Branches in Principal cities Milwaukee 14, Wis. Engineers'and Manufacturers of Fans, Washers, Heaters and Other Air-Handling Equipment CENTRIFUGAL FANS Bayley offers a complete selection of types, sizes and arrangements of centrifugal fans for ventilating, conditioning, industrial, and mechanical draft service, with slow-speed, power-limiting, or medium speed wheels. Made in single or double widths, with capacities up to 300,000 cfm or more. Smaller sizes have reversible hous ings for convenience and economy. INDUSTRIAL FANS Bayley Industrial Fans are available in a wide range of sizes and constructions from which to select the unit best fitted for any application in exhausting, conveying, cleaning, drying, blast, draft, or similar duties. Type "EX" is proportioned primarily for medium pressures and capacities usually encountered in materials handling or exhaust. Type "H" is similar, but proportioned for relatively higher pressures and smaller volumes. Designs are adaptable to suit virtually any requirement of tempera ture, corrosion-resistance or other severe operating conditions. VENTILATING FANS Type "F" FanB are equipped with wheels having forward- curved floats, effecting a slow-speed characteristic. The floats of the wheels supplied with Type "A'P" Fans are backwardly inclined, producing a non-overloading characteristic. Choice of fans is determined by the design conditions of the individual installation. VENTILATING SETS--Compact, unitary Ventilating Sets are manufactured with drive complete, ready to use, direct-connected and belted styles with capacities to 15,000 cfm. These handy units serve a wide variety of applications in ventilation and exhaust, for kitchens, lavatories, gymnasiums, restaurants, garages, halls, hospitals, laboratories, industrial plants, and many other locations. May be used for supply, exhaust or both. They can be equipped with weather-protection hood for outdoor or penthouse installation. Carefully engi Type Wheel neered and sturdily built to give long-lasting, efficient service. AIR WASHERS Because Turbo washers atomize by mechanical means, they cannot clog, hence are admirably suited to handling air contaminated with particulate mat ter. Standard pressure-nozzle washers also available for use where dust content is light. Turbo Washer BLAST HEATERS--The finless, long-lasting iron pipe coils of Chinook Heaters will not clog, therefore maintain full capacity longer. Pipe-within-a-pipe arrangement has single header for supply ana return, cannot short-circuit, and absorbs expansion and contraction without damaging stresses. A size and type for any blast heating application. Chinook Healer 1277
