Industrial work sites can be challenging. Confined spaces, weak air circulation, and heavy work can compromise safety, and, at the least, make workers uncomfortable. The solution is the VAF series of Dry Air Technology ventilators. They effectively ventilate confined spaces, increase the flow of fresh air, are lightweight, and easy to set up. In 1993, Dry Air Technology bought the first portable ventilator made of high-density polyethylene, the VAF-3000, to the marine industry. It has been a technological breakthrough ever since. Available in a variety of sizes with positive and negative airflow, these portable ventilators are dependable and perform well under the toughest conditions. These fans feature a dual wall shell design that protects the internal chamber from external damage, and epoxy coated metal components to prevent corrosion built for rough handling.
