Ventilator, Gravity

Definition

A gravity ventilator is a device installed in an opening in a room or building that uses natural air movement to remove stale air and replace it with fresh air.

Purpose

Gravity ventilators provide passive ventilation by taking advantage of natural airflow to improve indoor air quality. They help reduce humidity, remove odors, and lower indoor air pollutants without the need for mechanical systems.

Examples of Use

• Residential Homes: Installing gravity ventilators in attics and basements to facilitate natural ventilation and prevent moisture buildup.
• Industrial Buildings: Using gravity ventilators in warehouses and factories to improve air circulation and remove heat and fumes.
• Agricultural Facilities: Applying gravity ventilators in barns and greenhouses to maintain proper air quality for animals and plants.

Related Terms

• Natural Ventilation: The process of supplying and removing air through natural means without mechanical assistance.
• Passive Ventilation: Ventilation that relies on natural forces such as wind and buoyancy to move air in and out of a building.
• Roof Vent: A vent installed on a roof to allow hot air and moisture to escape from the attic.

Notes

Gravity ventilators are cost-effective and environmentally friendly, as they do not require electricity to operate. Proper placement and sizing are important to maximize their effectiveness.
