The Thermoflow® low-profile natural ventilator is very effective at evacuating large amounts of warm air and smoke. It is particularly useful in low-temperature climates that need a lightweight ventilator, because it has a built-in damper that can cut-off air-flow during cold weather.

It has been designed to provide superior air-flow capacity levels with minimal roof load and wind load. Each unit is made of galvanized steel, with sizes ranging from 5’ thru 12.6’ wide. Simplified installation make it easy to install on almost any rooftop.
