GEV Gravity Operated Roof Ventilators

Description

Continental Fan’s new GEV Gravity Operated Roof Ventilators exhaust stale or contaminated air through the pressure difference between the outside and inside air. An efficient throat and hood design allows for a high volume of fresh air intake while minimizing the induced pressure drop.
