Model ST Hooded Ventilator

Model ST hooded natural ventilator

The Model ST ventilator hoods are designed for intake, or relief applications with either natural gravity or positive pressure systems. The ventilators feature a low silhouette, architecturally appealing styling to mount close to the roofline.

The result is minimum impact on the building silhouette. Available in galvanized steel (Model ST G) or aluminum construction (Model STA). These hoods are designed to be strong enough to handle the snow loads found in the severest of climates.
