EMPIRE

Empire wind-driven turbine ventilators are available in throat diameters from 4 inches to 24 inches. Airflow ratings at 4 mph wind speed range from 126 CFM for the 4-inch model (TV04G) to 2,350 CFM for the 24-inch model (TV24G). Intermediate sizes include 6-inch (147 CFM), 12-inch (631 CFM), 14-inch (700 CFM), 16-inch (950 CFM), and 20-inch (1,700 CFM). Head diameters vary accordingly, from 10-1/4 inches to 35-3/4 inches. All models feature steel housings and external bracing. Bearing types include lower thrust ball bearings on smaller models and oilless bronze upper bearings on larger models such as the 16-inch and 24-inch units. These ventilators are designed for passive roof ventilation applications.

The Empire siding vent kit (MPN SOR1) is a steel venting accessory for gas wall and ceiling heaters. It is designed for surface mounting on wall furnaces to provide an exhaust path through exterior siding. The kit has opening dimensions of 2 inches x 3-1/4 inches x 2 inches. It is constructed from steel for durability and is classified as a siding vent kit under the venting for gas heaters product type. This kit is used when a gas wall furnace requires venting through a building's exterior siding, ensuring proper exhaust of combustion gases. It is a component in the installation of Empire gas heating appliances.

Empire turbine ventilators use two bearing types: lower thrust ball bearings and oilless bronze upper bearings. Models with lower thrust ball bearings include the 4-inch (TV04G), 6-inch (TV06G), 12-inch (TV12G), 14-inch (TV14G), and 20-inch (TV20G) units. The 16-inch (TV16G) and 24-inch (TV24G) models feature oilless bronze upper bearings. Oilless bronze bearings are designed to operate without additional lubrication, reducing maintenance requirements. Lower thrust ball bearings support the rotating assembly and handle axial loads. Both bearing types are intended to provide reliable operation in passive ventilation applications. The choice between bearing types may depend on specific model size and application requirements.

Yes, Empire wind-driven turbine ventilators are used for passive roof ventilation to exhaust hot air, fumes, and moisture from industrial and agricultural buildings. They operate using wind energy, requiring no electrical power. The range of sizes and airflow capacities allows selection based on the volume of air to be exhausted and the available roof space. For example, the 24-inch model delivers 2,350 CFM at 4 mph wind speed, suitable for large spaces, while smaller models like the 4-inch unit at 126 CFM are appropriate for smaller areas or specific exhaust points. Steel housings and external bracing provide structural integrity for rooftop installation. These ventilators are commonly used in warehouses, factories, and agricultural facilities.

Empire wind-driven turbine ventilators are constructed with steel housings. The steel housing provides durability and resistance to environmental conditions. External bracing is a standard feature, adding structural support to the rotating assembly. The turbine wheels are also made of steel, contributing to the overall robustness of the unit. This construction is consistent across the range, from the 4-inch to the 24-inch models. The use of steel is typical for industrial ventilation equipment intended for outdoor installation on roofs. No other materials are specified for the housing or bracing in the available product data.
