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.

AMCA Certified Fans What You need to Know before Making a Purchase

By David Long

AMCA certification transforms fan selection from guesswork into data-driven decision making. Independent third-party testing verifies that performance curves, efficiency ratings, and sound levels reflect laboratory-tested reality, not marketing claims. For facilities where ventilation impacts production, safety, or energy costs, certified fans eliminate costly specification errors, system underperformance, and redesigns. Understanding what AMCA certification means and how to evaluate certified manufacturers is key for long-lasting and efficient air movement systems.
