Builders of Heating, Ventilating, Cooling, Purifying, Humidifying and Air Washing Equipment; Exhaust and Drying Apparatus, Mechanical Draft and Blast, Fans and Blowers of all Types Bayley Plexiform Fan: Is a multi-blade fan for supplying air for heating and ventilating systems, manufacturing processes, drying systems, forced and induced draft sys tems. It is suitable for handling high or low temperature gases at medium or low pressure. Will deliver maximum quanti ties requiring minimum space with great economy. This is a distinct Bayley product, high class material and workmanship, properly designed to avoid excessive vibration and overstressing of parts. Inlets and outlets are properly sjzed for maximum delivery and maximum efficiency. Fans are fur nished in single or double width of any required arrangement and with sleeve or anti-friction bearings. Aeroplex Fan: Is of high speed design with self limiting power characteristics. Application parallel to the Plexiform Fan. Highly efficient and quiet in operation. Bayley Exhausters and Pressure Blowers: Type "B" exhaust fan is for heavy duty, hand ling refuse from industrial and textile plants. Type "SE" is used in handling smoke, fumes and dust laden gases. Type " H " for high-pressure work. These units are highly efficient and of high class design and workmanship.

This atomizer requires very little attention, and will operate successfully under low water pressure. The orifices are large and this atomizer, unlike high pressure nozzles, cannot clog. Bayley Chinook Heating Sections: The Chinook sec tion is used with blast heating, venti lating and drying systems, and is suit able for high or low pressure steam cir culation. The base is divided into two chambers. Steam enters (see cut) the lower chamber, ris ing through H-in. pipes located within the 1^-in. pipes leading from the upper chamber. Condensation takes place in the larger pipes, the water falling into the upper chamber and draining away through the return outlet. The Chinook can be repaired in the middle of the bank without breaking steam connections or taking down a section. Shipped assembled in smaller sizes, and . knocked down in the larger units. May be installed in horizontal or vertical position. Bayley Chinookfin Heating Sections: Are the same design as the Chinook Heaters, using heavy gauge copper fin tubes. As compared with Chinook it is much lighter and occupies less space. Bayley Plexfin Unit Heaters: This unit incorporates Chinookfin radiation and Plexiform or Aeroplex fans. The fan assem bly including top plate and motor is re movable as a unit for main tenance and inspection. The heating element is a re movable unit. Casing all welded extra heavy gauge.
