Gravent - Natural Ventilation System

The Gravent Ventilation System is an advanced natural ventilation solution specially designed for industrial environments. At its core, Gravent is a scientifically engineered “roof opening system” that ensures efficient airflow while preventing rain ingress and wind backdraft.

Built on proven ventilation principles, Gravent delivers predictable and reliable performance, backed by expert ventilation system design and decades of industry experience.

How Gravent Works

Gravent ventilators utilize natural airflow driven by pressure differences between the inside and outside of a building. This airflow is primarily created by:

Stack Effect – Warm air rises due to temperature differences inside the building
Wind Movement – External wind flowing across the structure
Building Height & Heat Load – Increased height and internal heat sources improve airflow efficiency

This natural process ensures continuous ventilation without the need for powered systems, making it energy-efficient and cost-effective.
