This type of fan is usually enclosed in a steel-plate casing ofsuch form as to provide for the free movement of the air as itescapes from the periphery of the wheel. An opening in thecircumference of the casing serves as an outlet into the distribut-ing ducts which carry the air to the various rooms to be ven-tilated, or to the furnaces in the case of mechanical draft. 189 190 HEATING AND VENTILATING PLANTS.
