Professional Engineered Airflow Design

Expertise decides the details of the ducting system while the software calculates the outline.


Ventilation calculator based on SIA recommendation supported by our partner calculates the recommended duct diameter, fan size, and expected air pressure.

All you need to do is to send a few parameters by clicks of the mouse, including

  • • Tunnel cross-section
  • • Tunnel length
  • • on-site(working temperature, altitude, etc)


Duct diameter is not the only thing to consider when faced with the complex topography. An appropriate ducting system would lessen your operation costs based on normal ventilation, which requires various types of flexible duct to be included.

  • • Experience in serving over 3000+ clients from tunneling to hydraulic field
  • • A full ducting solution with specific types, shapes, angles, and lengths.
