Natural Ventilation System

Natural Ventilation System

A Natural Ventilation system utilizes a ceiling opening for warm air exhaust and a natural intake for fresh supply air to create a better working environment. Warm air naturally rises, a natural ventilator just allows it to escape. Contact the team at Moffitt today for a cooler, more comfortable facility.

A natural system has zero operating costs and zero maintenance costs. It is the natural solution for commercial and industrial building ventilation.

Moffitt has been designing natural ventilation systems for over 60 years. We utilize advanced ventilation design techniques, such as CFD computer modeling and wind-tunnel testing, to find the right solution for every project. The Moffitt team has implemented ventilation systems in hundreds of facilities in dozens of industries.

A natural system utilizes non-powered, passive exhaust equipment (MoffittVent or MatrixVent) along with passive intake devices (EcoStream wall louver) to improve building ventilation and create a better building environment.
