Large-Scale Hangar Airflow Control

Hangars present a unique physics challenge where massive air volumes and high-bay ceilings lead to extreme thermal stratification. Terrui 24ft (7.3m) HVLS fans address this by moving a column of air that wraps around airframes and ground equipment. This consistent circulation stops moisture from pooling on sensitive aircraft skins, significantly reducing corrosion risks. In summer, the system generates a perceived 10°F (5.6°C) cooling effect for maintenance crews, while in winter, it eliminates the 30°F (16.7°C) temperature gap between the roof and floor. By redistributing trapped heat, facilities can drop thermostats by 3–5°F (2–3°C), delivering an immediate return on investment.

Active Maintenance & Terminal Extraction

Aviation maintenance bays and terminal transition zones require active air exchange to manage fumes and humidity. Terrui negative pressure fans provide the necessary Air Changes per Hour (ACH) to speed up paint curing and aircraft drying. The performance range—from the 71,000 m³/h output of 55-inch units (1,400W) to the massive 230,000 m³/h capacity of the 98-inch series (5,500W)—ensures that exhaust and moisture are flushed out before they can settle on high-value assets. In terminals, this airflow barrier stabilizes conditions near cycling doors, preventing conditioned air from escaping. Linked via the Terrui Connect IoT platform, the entire network automates based on real-time sensors to protect assets and passenger comfort.
