Natural Ventilation

Consider natural ventilation to create a cooler and more comfortable building with no operating costs or energy consumption. Natural ventilation is the evacuation of hot air and fumes directly through an opening in the ceiling. The opening is covered by a weatherproof ventilator, and air-flow is supported by fresh intake air at the floor level. We have several ventilator varieties and can help you select the best fit for your space.

MoffittVent™ - Large Natural Ventilator

natural ventilation - Moffit Vent

LightStream - Natural Intake / Daylighting

natural ventilation - Moffitt Lightstream

The LightStream hinged window can be used commercially or industrially. This dual-purpose vent draws cool air in when it’s positioned low on the wall and exhausts warm air when it’s mounted higher. Translucent panels allow ample daylight to enter when the unit is closed.

Apollo - Day-to-Day Natural Ventilation / Daylighting

natural ventilation - Moffit Apollo

The Apollo is a good choice for natural ventilation and daylighting in heavy commercial and industrial facilities. It has dual-opening flaps to allow warm air to exit the building.
