This is a positive turning device, revolving on ball bearings, and is noiseless in operation. It is not only weather-proof but is a real ventilator, doing its work at all times and under all conditions.- By means of utilizing the air current, a powerful ejector principle is constructed, insuring high velocity in the discharge of the air. The high efficiency will allow the use of smaller ventilators, or if the same size ventilator is used, greater results can be secured. With this ejector, it is not a question of temperature of the air to be exhausted, and heavy gases, smoke or cold air are lifted and discharged with case. Furnished in galvanized iron unless otherwise ordered.
