What is a passive attic fan? Passive vents use the natural forces of nature, such as wind and convection, to move the air through your attic. These vents have no moving parts, create no noise, and are virtually maintenance-free. The common types of passive roof vents are static, ridge vents without a baffle, and gable end vents.
