Ventland (Dongyang Ventilation) is a Korean manufacturer focused on one mission since 1980: deliver clean, reliable airflow for buildings without adding complexity. We specialize in roof and industrial ventilation, combining field-proven hardware with straightforward engineering.

Our products include the Ventulator™—a stationary, wind-induced roof vent that uses guide-vanes to harness the Bernoulli effect—alongside backdraft prevention caps and dampers, mixed-flow and axial blowers/fans, and SMC roof hoods and curbs. Every design prioritizes installability, weather protection, and long service life with minimal maintenance.

What customers value:

Engineering-first development that turns physics into practical performance.

ISO 9001 quality discipline for consistent fit, finish, and airflow.

Energy-wise solutions that leverage wind and natural draft to cut operating costs.

Responsive technical support for submittals, jobsite questions, and after-sales needs.

Ventland solutions help remove heat, humidity, and fumes in warehouses, factories, workshops, and commercial roofs across Asia and beyond. If your project requires dependable passive or powered ventilation—with clear specifications and on-time delivery—Ventland is your partner.
