These exhaust and supply
ventilators are used to exhaust (relief) or supply (intake) air from or to an
enclosed area without the need for a power operated fan. They rely on a difference
in static pressure inside and outside the area to create an air flow through
the ventilator from the area of higher pressure to the area of lower pressure.
If the enclosed area is under a negative pressure, air will flow into the enclcosed
area (intake). If the enclosed area has a positive pressure, air will flow from
it to the outside (relief).
Thse units can also operate
as gravity ventilators, allowing air to flow from an enclosed area using the
"Stack Effect." The amount of air flow will depend on the temperature
difference inside and outside the area and the height difference between the
ventilator and the outside air intake to the area.
