Ventilation is the intentional introduction of ambient air into a space. Proper ventilation is a critical consideration for buildings.

Curvent International – design, manufacture and install both natural and mechanical ventilation systems. We can offer more than 35 years of expertise for the most optimal and cost-effective ventilation system.

Natural Ventilation relies on natural sources such as the wind and temperature difference between a building and its environment in order to flow fresh air through a building.

Mechanical Ventilation is a process of replacing air by removing internal air and supplying fresh air into a space with the use of mechanical devices like ductwork and fans.
