Roof Propeller Fans, Belt Driven and Direct Driven

General ventilation power roof ventilators designed for efficiency and economy. 

Low profile PRVs are suggested for use in commercial and industrial applications including factories, warehouses, commercial buildings, machine rooms or any situation requiring the movement of air. 

High profile PRVs are suggested for use in industrial applications where it is necessary for the fan assembly to be located above the roof and where motor, belts and bearings must be isolated from the airstream.  

These 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. 

With many commercial and industrial buildings such as factories, warehouses, parking garages, shopping malls and department stores a means of venting hot gases and smoke in the event of a fire is required. 

Our Type H PRVs are especially designed, built and proven by independent test to meet this essential need. They reliably extract large volumes of hot gases and smoke regardless of building configuration, location or weather conditions. They withstand high temperatures for long periods. 

A reliable ventilation system that can operate during a fire is both vital and essential. It prevents smoke logging, allows people to escape quickly, minimizes damages to property and contents and enables firemen to attack the fire without hindrance. 

These PRVs have the added advantage of providing normal day-to-day ventilation and in many cases can also be fitted with ductwork for use in multi-story buildings. 

The unique Type H power roof ventilator concept provides a solution for emergency heat and smoke venting that is dependable under the most extreme circumstances.

Hooded Roof Ventilators, Exhaust and Supply

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 CMFs and a variety of configurations. 

There are types offering belt and direct driven propellers, exhaust, supply or reversible are movement, and filtered air supply. 

Most hooded PRVs can be supplied less fan component for use as a gravity ventilator or as an air intake. 

Combinations of these various types can be used and still maintain a uniform and attractive rooftop appearance. 

Use of the power combination of hooded power roof ventilators assures an effective ventilation system at exceptionally low cost. 

Type RE 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. 

Type RE 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

Type PT - Power Tube Fan Make-Up Air System

 When exhaust fans are used to provide ventilation, both for industrial and process exhaust and personnel comfort, a negative air pressure is created within the building. This negative pressure causes problems. Process exhaust systems are less efficient and may not work properly. Down flow can occur through gravity vents and result in the back venting of products of combustion from flues and stacks of heaters and process equipment. Drafts are created that are a discomfort to employees. Our Power Tube Fan Make-Up Air System solves all of these problems economically, even on the coldest winter day.
