The MoffittVent™ is the most effective and efficient natural ventilation device on the market today. This popular ridge 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 actually improve ventilation in many situations.

Each MoffittVent™ ventilator is designed to withstand winds up to 130 MPH at grade. It can also be manufactured to withstand higher speeds as well.

In fact, the MoffittVent™ can be custom engineered to meet any local building codes or special requirements. So whether the ventilator needs to be adapted for high snow loads, corrosive environments, or any other condition, Moffitt can help. Consequently, even if the unit just needs to be painted a special color to match the other architecture, Moffitt can do that too. Basically, the MoffittVent™ can be made to fit any building’s needs.

Turn-Key Service is available for this ventilator. Moffitt Mechanical specializes in industrial ventilation contracting. Furthermore, MoffittVent™ installation is their focus. Ask your sales representative about installation services.

The MoffittVent™  natural ventilator has been manufactured for over 55 years. It is the premier large-size, high volume gravity ventilator in the U.S. That’s probably why we’ve been ventilation’s natural solution since 1961.
