energy savings of the moffittvent natural ventilator

The MoffittVent is the most effective and efficient natural ventilation device on the market today. This large capacity ventilator exhausts large volumes of warm air without letting any rain in.  Wind direction and velocity do not negatively affect performance. In fact, higher winds can improve ventilation in many situations. The standard model can withstand winds up to 130 MPH, but we can modify it to withstand even higher wind speeds.

Our team custom engineers each MoffittVent to meet local building codes, specific requirements, and customer request. This includes adaptations to meet high snow loads, corrosive environments, special color coatings to match the building architecture, and more. If an industrial building needs a MoffittVent, our team will design one for it. Moffitt has custom designed, manufactured, and installed the MoffittVent natural ventilator for over 60 years.
