Complete une manuiactured in Canada by Canadian Blower & Forge Co., Ltd., Kitchener, Ontario Manufacturers of Heating and Ventilating Equipment, including: Multiblade Fans, Pipe Coil Heaters, Unit Heaters, Carrier Air Washers, Exhaust Fans, Blowers, Dust Collectors, Disc Fans, Spray Nozzles, Me chanical Draft, Drying Equipment, Multistage Blowers and Exhausters Complete descriptive literature sent on request The New Silex Conoidal Ventilating Fan An improved type of ventilat ing fan, designed from our experiments and experiences to reduce audible noise to a minimum. The housing is a "rolled-up evase stack," con verting air velocity leaving I the rotor into static pressure. The cone is carried out be yond casing in order to get best conversion efficiency, and to provide an extremely quiet stream line fan cut off. Unit Heaters Unit Heaters Air Washers One-Piece eliminators and scrub bers that are easily assembled in a few minutes and give great clean ing effect. Spray nozzles prevented from clogging by tank-width screen. Original efficiency is maintained indefinitely by a few minutes flushing out each week. Buffalo Niagara Conoidal Fans handle large quantities of air at high efficiency under big over loads in industrial plants. Low speed and great capacity well suited to belt drive. The New Buffalo Highboy and Low boy Heaters, units of large capacity, heat and ventilate large areas economi cally. The heating coils and centrifugal fans are arranged for maximum efficiency. Every part of these heaters is accessible Highboy for inspection. Available in three different lengths and two heights for mounting and may be placed vertically or horizontally. Buffalo Breezo Propellers Fans are very suc cessfully used for removing steam, odors or foul air in shops, mills and factories. Belted or direct motor driven types. Mechanical Draft Apparatus Buffalo Forced and Induced Draft Fans have kept pace with the rapid strides in modern boiler room efficiency. Ruggedness and reliability have always been our watch word. Improvements in efficiency--1 stronger and better balanced rotors for the higher peak loads--liners and welded construction to combat the erosion of powdered coal are some of the things we are doing and continuing to do. 640 Fans and Ventilating Equipment De Bothezat Impeller Go., Inc. 1922 Park Avenue, New York, N.

De Bothezat Fans are guaranteed to have a nonoverloading power charac teristic, that is to absorb at constant revolutions practi cally the same power what ever the static pressure under which they are oper ating for the whole range between free delivery and no delivery. This impor tant property insures the complete safety of their operation under any condi tions to be met in practice. De Bothezat Pressure Fans made in all sizes from 8 in. to 10 ft. Motors for these fans are furnished from 3^o hp* to 100 hp. The capacities of the fans run from 360 c.f.m. to 254,000 c.f.m. Static pressure from ^ in. to 3 in. High efficiency and large air volume, together with high pressure characteristics are a few of several qualities which distinguish De Bothezat Disc Pressure Fans. GIANT FAN Sizes from 5 ft. to 10 ft. Powers from 2 hp. to 100 hp. Volume from 16,000 c./.m. to 254,000 c.f.m. Static Pressure from fa to 2 in. Speed from 175 r.p.m. to 700 r.p.m. Fan and motor mounted on same base secur ing perfect align ment. Requires mint-. mum floor space. Chain driven, texrope drive, or directly connected THE BIFURACTOR For special Ventilating jobs where fumes of excessive temperature or corrosive character are to be removed. The bifurcator is a device that permits the use of a straightway duct. It eliminates right angle bends and long shaft connections, at the same time protecting and automatically cooling the motor. The fan chamber is stream lined in section, and the bifurcated duct is not reduced in area at this point. Full details on request.
