The Ultimate System for Mega-Space Ventilation

The Modular Roof Ventilator is not just a fan-it's a scalable, engineered ventilation system designed for the world's largest enclosures. A single module delivers 15,000–40,000 m³/h, and multiple units can be combined to move millions of cubic meters per hour. Designed for extreme-duty applications like aircraft hangars, mega-logistics hubs, and automotive plants, this products provides a powerful, coordinated exhaust solution where standard units are insufficient.

Industrial-Grade Power and Precision Control

Each unit within the modular roof ventilator system is a high-performance powerhouse, operating at 150–800 Pa static pressure with a total efficiency of 65–75%. Power scales from 22 kW to several hundred kilowatts per module. It is driven by a heavy-duty, inverter-ready motor (7.5–55 kW, 380V/50Hz, IP55, H-class, IE4) running at 980–1480 r/min. Despite its power, each fan maintains a noise level of 75–85 dB(A) at 3 meters. Exceptional G2.5 balancing ensures system-wide vibration remains below 4.5 mm/s, protecting structural integrity.

Engineered for Resilience and Fast Deployment

Built to withstand the toughest conditions, the modular roof ventilator system features a structural design with Grade 12+ wind resistance and IPX4 weather protection. It includes integrated motorized backdraft dampers and a multi-layer roof sealing system. Safety is paramount, with a Category II lightning protection network and a heavy-duty steel base designed for 9-degree seismic zones. Fully pre-assembled and tested at the factory, the entire module arrives site-ready for a single-lift installation, dramatically reducing project timelines and ensuring reliable, large-scale ventilation from day one.
