Gravity Ventilators

Gravity ventilators offer the Turbine, Pul-Air and Insul-Air models. Turbines are ideal for the general ventilation of factories, farm and agriculture buildings, commercial and public structures and homes. The Pul-Air is a simple device designed to permit an easy outward flow of air with no internal obstructions or moving parts requiring maintenance. The Insul-Air is the ideal choice where an extended airshaft is necessary (to clear the peak of the roof, for example). It features all the study construction details of the Pul-Air plus an extended airshaft and an integral flat mounting base.
