Gravity Ventilators (GV-I and GV-E)
The Ventex GV-I (Intake) and GV-E (Exhaust) are rooftop gravity ventilators offering superior weather resistance, efficient performance, and rugged durability. Constructed from 18 GA. steel with standing seam and snap-lock hood seams assembled with self-sealing fasteners, continuous welds along all vertical base corners and seams, and an anti-condensate roof coating to prevent condensation. A 360° throat opening and 0.051 flattened aluminum expanded metal screen provide all-directional airflow and weather protection in a mill finish.

Additional Notes
The GV-I and GV-E gravity ventilators are designed for rooftop applications where reliable passive ventilation is required without mechanical assistance. The intake and exhaust configurations allow for balanced airflow design across a building's rooftop ventilation system. The 360° throat opening ensures consistent performance regardless of wind direction, while the steel construction and anti-condensate coating are suited to demanding outdoor environments.
