High-Temperature Industrial Fans How to Select and Specify Industrial Fans for High-Temperature Environments

By David Long

Standard industrial fans aren't built for sustained heat. Bearings seize, belts degrade, and motors burn out long before they should. High-temperature fans are different machines entirely, engineered with heat-resistant materials, isolated motors, specialized bearings, and thermal expansion management. This guide covers the engineering decisions that separate fans that last from ones that fail, and what to look for when specifying the right one for your application.

Industrial Fan System Effects Six Real-World Case Studies

By David Long

Industrial fans are tested in labs under ideal conditions, but they don’t operate there. Elbows, dampers, security bars, and staged commissioning all create system effects that can cause vibration, premature failure, and performance loss in the field. These six real-world case studies, drawn from Hartzell’s 2026 AMCA conference presentation, show how system effects show up across manufacturing, wastewater, correctional, and pulp-and-paper applications, and what to do about them.

Corrosion Resistant Fans How to Choose the Right Fan Material for Harsh Environments

By David Long

Not every corrosion-resistant fan is the right fit for every environment. The chemistry, temperature, and moisture in your airstream all affect which material will actually hold up long term. This guide compares your options and helps you calculate the true cost of ownership so you're not replacing the same fan every three years.

Heavy-Duty Centrifugal Fan Performance Verified Through AMCA 210 Testing Design, Customization, and Testing Behind a Custom Centrifugal Build

By David Long

In March 2026, Hartzell Air Movement conducted AMCA 210 performance testing on its newest heavy-duty centrifugal fan at the company’s Piqua, Ohio facility. Designed for high-pressure industrial applications, the fan demonstrates how structural engineering, precision balance, and in-house testing work together to ensure reliable performance. This post breaks down the design features, customization choices, and testing process that validate performance before installation in the field.
