A tool designed for industrial engineers and fan users, the Chicago Blower fan engineering app includes information on the basic fan laws. In addition, the app is equipped with application formulas, temperature and altitude correction factors, duct friction loss, tip speed values and corrections for density. Other calculations include area and circumference, displacement to velocity, and amps to horsepower.

The app can be used internationally because the formulas and factors can be run through the metric-to-English converter.

In addition to the calculator functions, Chicago Blower, Glendale Heights, Ill., included fan information from the company. Each of the company’s product bulletins and manuals can be downloaded. Also, current customers and representatives can access the order-tracking system to follow fan production schedules, confirm shipping dates and track shipment information.

The app is available on Google Play and Apple iOS App Store.
