Type C Propeller Fans

A general ventilation fan designed for efficiency and economy. 

Suggested for use in commercial and industrial applications including factories, warehouses, gymnasiums, underground parking garages or any area requiring ventilation where side wall mounted fans are desirable. 

Type C fans are rugged and dependable. They are available in a large selection of CFM's and pressures. 

The fans can be arranged for exhaust or supply use. 

A wide choice of accessories are available to complete a well-balanced and specifically engineered air movement system. 

A direct drive general Type UD Propeller Fan designed for use in commercial and industrial applications where low sound levels are important and relatively low CMFs are appropriate. 

Type UD fans combine the durable construction and reliability needed for industrial applications with the quietness and good looks required for office or laboratory. They offer the low maintenance requirements that are characteristic of direct drive fans. 

By combining the Type UD fan with a companion wall sleeve and other accessories, a ready-to-mount wall ventilation package is provided. 

The Type UD fan may be assembled for air exhaust or supply usage.

Type J 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. 

Type JT 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. (Type JTB) 

American Coolair 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. 

Type HS 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 American Coolair Type HS power roof ventilator concept provides a solution for emergency heat and smoke venting that is dependable under the most extreme circumstances.

Suggested for commercial and industrial uses such as make-up air systems, booster fans, return air fans or to exhaust contaminated or high temperature air. 

Type T fans are available in a large selection of CFMs and operate efficiently against static pressures up to 2 inches. 

A true vane axial Type VA fan designed for use in a wide range of commercial or industrial applications. 

High pressure efficiency permits the fan to be installed anywhere in the system; in any position. It can be used for either supply or exhaust by simply turning the entire fan unit to flow air in the desired direction.

Type VA fans are extremely compact and well suited to locations where space is limited. In many instances, these fans are mounted directly to the duct work. 

As a result of very close tolerances and carefully matched vanes and rotor, the Type VA fan offers exceptional performance within its size range.

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. 

At a later date this unit can be converted to a power roof ventilator by simply installing the proper style American Coolair Type C Fan. 

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 and RES 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 and RES 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.
