Natural Ventilation System

natural ventilation

A Natural Ventilation system utilizes a ceiling opening for warm air, along with a natural intake for fresh supply air, to create a cooler and more comfortable building envelope. Warm air naturally rises, a natural ventilator just allows it to escape.

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

Moffitt has been designing natural ventilation systems for over 55 years. We utilize advanced ventilation design techniques, such as CFD computer modeling and wind-tunnel testing, to find the right solution for each and every project. The Moffitt team has implemented natural ventilation systems in hundreds of facilities in dozens of industries.

Natural ventilation systems utilize non-powered, passive exhaust equipment (MoffittVent™ or Labyrinth) along with passive intake devices (EcoStream wall louver) to make a building cooler and more comfortable.

Benefits of Natural Ventilation

  • Eliminate operating costs
  • Eliminate maintenance costs
  • Operate silently
  • Remove hot, humid air
  • Remove smoke and fog
  • Increase fresh air at the operating floor
  • Improve personnel comfort
  • Create a neutral pressure environment
  • Encourage environmentally conscious practices
