Electricity for Ventilation

VENTILATION, says an American journal, is'a subject that is vitally interesting to the average man, who recognises it as a necessary factor in assuring good health in the individual as well as efficiency in his work. Scientific authorities have long and constantly pointed out that good ventilation is the replacing of bad or used air with pure, fresh air brought in from outside. The problem of ventilation is to remove the breathed air and replenish the supply of fresh air. The answer to this problem is properly designed positive electrical ventilation. It assures the entrance of fresh air andthe removal of the used air at all tines. It creates no draughts, permits no’ dead air pockets, and ensures a supply of fresh: air in all parts of the room.
