The Zoom Ventilator is a confined space fan that offers a small size for any narrow space. Its flex hoses can transport ducted air up to 125 ft. The Zoom Ventilators are super lightweight and compact. Their low amp and powerful, sealed motors can efficiently deliver dry air to ventilate, create negative air pressure or simply to help complete any drying process for a wide variety of construction applications. The Zoom Ventilator can be used without hoses to create high volume air circulation in gyms, hallways and other large areas. With its ducting hose, the Zoom Ventilator is the perfect fan to deliver a continuous flow of fresh air to subterranean manholes and sewers.
