Finding the Right Fan Starts with One Key Number📌
When selecting a fan for your AHU system, static pressure is key.
It comes down to overcoming total resistance—internal components like filters (60–120Pa), coils (25–30Pa), and heat recovery wheels (200–300Pa), plus external ductwork resistance (typically 4–8Pa/m).
Getting this balance right means better performance, higher efficiency, and reliable airflow.
🌟For AHU applications, our Achelous Series high-static-pressure backward-curved centrifugal fans are designed to deliver exactly what the system demands.
