Direct-Driven Roof Fan Systems (Internal Motor)
Direct-Driven Roof Fans with internal motors are engineered for the effective expulsion of unpleasant odors, airborne moisture, fumes, and stale air directly into the atmosphere from rooftop levels. Featuring an integrated direct-drive motor assembly within a compact envelope, they eliminate mechanical transmission losses while delivering superior aerodynamic efficiency.
Capable of providing airflow capacities up to 12,000 m³/h alongside high static pressure generation, this series easily overcomes airflow resistance across vertical building shafts. Its weather-resistant protective cowl, dynamically balanced radial impeller, and standardized curb-mounting base ensure swift installation and dependable, low-noise continuous ventilation.
