Nowany local electric lighting plant can furnish powerby means of its wires to an electric motor whichwill revolve the fan with little attention. The sizesof these motors vary from one-half H. P. up; itbeing seldom that one of greater than two and one-half H. P. capacity is needed. Such a motor will revolve a fan 42 in diameterat a speed of 250 revolutions per minute, and move7,079 cubic feet of air per minute. This speed maybe increased, and the air moved will be increased inproportion. The care of the fan and motor can beeasily undertaken by any one possessing ordinaryintelligence as it can be made self oiling, and theamount of time needed to keep it in order shouldnot exceed one hour per week.
