Industrial Airflow Problems that Look Like Fan Failures Why System Changes—Not the Fan—Are Usually to Blame

By David Long

Industrial airflow problems are frequently misdiagnosed as fan failures when the real culprits lie elsewhere in the system. Increased system resistance, process changes that exceed original design capacity, poorly coordinated controls, contamination buildup, and installation modifications commonly cause airflow loss. Replacing the fan without addressing these underlying issues typically leads to repeated failures. Effective troubleshooting requires diagnosing the entire system rather than simply swapping components.

Why Hartzell Engineering Stands Apart A Prop Strike Story That Proves What 'Built to Last' Really Means

By David Long

Sometimes the best engineering lessons come from the worst days. A Cirrus SR22T suffered a severe prop strike, destroying the propeller but leaving the engine intact—thanks to the Hartzell Propeller composite design. Whether it’s aviation or industrial applications, Hartzell Air Movement products share the same philosophy: engineer for the moment that matters most, delivering durability, reliability, and protection when it counts.

Preventing Transit Damage How Hartzell Solved an Unexpected Challenge

By David Long

Fans were experiencing excessive G-forces during transit, causing issues after installation. Pre-shipment inspections confirmed equipment left our facility in excellent condition, yet some units arrived damaged at job sites. Rather than speculate, we gathered data. By installing G-force monitors on shipments, we identified the threshold where damage occurred. The solution? A quarantine protocol and visual indicators that eliminated installation delays and restored complete confidence in every delivery.
