Ventilation and Air Control

Ventilation & Air Control

Adequate ventilation is a necessity to maintain air quality for every underground mine site.

For a safe operating environment, it is essential to retain fresh air, prevent cross contamination of return air, and prevent gas build up from cavities without ventilation in place. We have provided the mining industry with steel fabricated ventilation control devices (VCD) and services for more than 15 years.

We offer our services in three ways:

  1. Direct product supply; where we design, build then deliver your VCD to site for you to install and maintain.

  2. Product supply and service; we deliver your VCD and provide technical expertise to manage audits and product ordering/stock control;

  3. Full service and installation by Minova’s Operations team to manage the whole process from design, installation, audits, maintenance and stock control and ongoing technical support. Giving you the time to focus on maintaining your operations.
