Flat Ridge Ventilator (FRV)
Applications (FRV)
The EA Flat Ridge Ventilator is designed to supersede traditional ridge ventilators in “hot” industries, such as steelworks, power stations, foundries, smelters, glass works and other industries in which high internal heat-loads are encountered. Because of its unique modular construction, it offers several advantages;
Low Profile: the modules are exceptionally low in height, this greatly reduces wind load on the building structure and lessening the need for reinforcement. Because of their height, traditional ridge ventilators are conspicuous and tend to dominate the building roof line, whereas low profile Flat Ridge Vents merge with the roof line.

Reduced Weight: a system composed of Flat Ridge Vents is generally two-thirds the weight of its traditional angle iron counterpart.
Ease of Installation: installation is a relatively simple process involving attachment to the purlins with screws or rivets.


Versatility: the new ventilator system can be installed on almost all types of industrial roofs, including sawtooth. It is not independent on roof angle for maximum efficiency, as long as the roof has a minimum pitch of 5 degrees.

Flexibility: Unlike traditional ridge ventilators which run along the full length of a building, Flat Ridge Vents can either be concentrated over specific “hot spots” or installed continuously along the roof ridge or any other part of the roof.
Expansion capability: If the heat-load requirements of an existing building are increased, the ventilator system does not need to be replaced. To accommodate the increased load, additional modules can be installed to accommodate new requirements.
Reduced roof sheeting: Since the Flat Ridge Vent covers more of the roof than a traditional ridge ventilator; less roof sheeting is required, therefore reducing cost.
