Designed for years of trouble free service, there is a Heil fan for all your corrosive air handling needs. These fans are constructed of solid fiber reinforced resin laminates with no metal parts exposed to the gas stream. A smooth interior surface minimizes friction loss and maximizes corrosion resistance. Heil fans are tested and rated in accordance with the standard test code for air moving devices published by The Air Moving and Conditioning Association. Heil fans are your best value, and best buy, for integration into your new or existing process, or as part of your Heil Single Source Solution System.
