Efficient Ventilation with Rooftop Axial Fans

Rooftop axial fans are designed to provide high-volume air movement for effective ventilation of commercial, industrial, and institutional buildings. Mounted on the roof, these fans are ideal for exhausting large volumes of air directly to the outdoors, helping to maintain a safe, comfortable, and controlled indoor environment. Their streamlined axial design allows for efficient airflow with minimal resistance, making them a cost-effective solution for applications such as warehouses, manufacturing facilities, and mechanical rooms. Rooftop axial fans are also available in various configurations to accommodate different air volumes, pressures, and installation requirements, ensuring reliable performance and ease of maintenance.


Hooded Power Roof Ventilators

General ventilation power roof ventilators designed to move large volumes of air quietly, efficiently and dependably. They are suggested for use in commercial and industrial applications including factories, warehouses and large commercial buildings.
These rugged PRVs are available in a broad range of CFMs and a variety of configurations. There are types offering belt and direct driven propellers, exhaust, supply or reversible air movement, and filtered supply air. Most hooded PRVs can be supplied less fan component for use as a gravity ventilator or as an air intake. At a later date this unit can be converted to a power roof ventilator by simply installing the proper style Type C fan. Combinations of these various types can be used and still maintain a uniform and attractive rooftop appearance. Use of the proper combination of hooded power roof ventilators assures an effective ventilation system at exceptionally low cost.


Upblast Power Roof Ventilators

Upblast power roof ventilators are designed for long life, low maintenance and all-weather performance. The proven upblast design is the most cost effective roof exhauster built today and offers the best value of all PRV types. These units are designed for general ventilation, efficiency and economical. Suggested for use in commercial and industrial applications including factories, warehouses, commercial buildings, machine rooms or any areas
requiring the movement of air, where it is necessary for the fan
assembly to be located above the roof. Belt drive PRVs are suggested where the motor, belts and bearings must be isolated from the airstream. The units provides an economical solution for most of these applications, while some models are suggested where a heavier duty unit or greater performance capabilities are required.


High Temperature Upblast Power Roof Ventilators

The high temperature endurance upblast power roof ventilators are designed and built to meet the increasing need for power venting the combustion by-products of a fire.
These units are designed to be installed in the roof systems of shopping centers, wholesale warehouses, hotel atriums and any other place where building codes require the removal of smoke and heat by power roof ventilators.

High-Temperature Endurance

High temperature fans were tested, and met the following time vs. temperature limits:
> 270 minutes at 500°F (260°C)
> 90 minutes at 700°F (371°C)
> 30 minutes at 1,000°F (538°C)


Recirculating Roof Ventilators

Recirculators are multi-purpose power roof ventilators.
They are suggested for use in commercial and industrial applications where there is sufficient ceiling height to create a temperature differential between the floor and ceiling. These applications include factories, warehouses and large commercial buildings. Recirculators function as normal power roof ventilators in warmer weather and as an energy-saving recirculation system in cold weather. Each unit is equipped with a reversible fan that
redistributes warm ceiling air throughout the plant and reduces the building’s heating requirement. With the flip of a switch, it can function as a conventional roof ventilator.
Configurations include exhaust, supply or recirculation.


Spun Axial Roof Ventilators

The spun axial fan is a low silhouette axial propeller roof ventilator that is compatible with modern architectural lines and also matches ILG’s centrifugal power roof ventilators. Spun axial roof ventilators shall have circular hoods of spun aluminum. Ventilators will be low in silhouette to conform to present architectural styles. Square bases will be constructed of aluminum. Ventilators will be equipped with galvanized mesh bird screen.
Units provide general supply or exhaust of low, medium or high air volumes in commercial, institutional and light manufacturing buildings.
