Because of the soft air supply, high wind frequency and no dizziness, it is very suitable for the elderly, children, hospital wards and other people who need nursing. In foreign countries, tower fans are mainly used in conjunction with air conditioners to strengthen convection and increase coolness, thus achieving good energy-saving effects.
