- A gravity relief ventilator is a type of natural ventilation that uses the force of gravity to help move air through a building1. The vents are typically located near the top of a building and allow hot air to rise and escape while cooler air is pulled in from lower openings1. Gravity ventilators, or passive ventilation, work on the concept of providing adequate air circulation for a space, while using no mechanical parts2. They do not use fans, belts, or any kind of motor to drive air2. Instead, they work on pressure differential between the inside and outside of your construction project2. A gravity ventilator consists of a fan built into a hole through a roof in a house3.Learn more:✕This summary was generated using AI based on multiple online sources.
