Building Ventilation

Energy recovery systems have become a popular way to heat and cool homes as well as commercial buildings. Energy recovery applications typically use two fans that provide air through a heat exchanger that "treats" the air by heating or cooling it before it enters the building. Buffalo Blower's plenum and forward curved fans are typically used for energy recovery applications and offer a wide range of performance and flexibility. Generator rooms require a wide range of fans to optimize the performance of generators and other equipment. Exhaust fans are used to prevent heat buildup within the generator room, while supply fans are used to provide fresh air for combustion and efficient generator performance. Room size, space limitations, and mounting capabilities will determine the exact type of fan needed for each specific application. As a leading manufacturer of air moving equipment, Buffalo Blower offers numerous fan types for meeting any generator room specification.

Rooftop exhaust fans are designed to remove heat and odors from buildings to improve air quality and occupant comfort. Areas such as cafeterias, locker rooms, office spaces, restrooms and warehouses often have unique requirements specified by local codes and utilize a wide range of rooftop exhaust fans. To accommodate these various types of environments and ventilation systems, Twin City Fan offers a complete line of products to support every rooftop exhaust application. These applications can range from clean airstreams with minimal filtration all way to high density offices and health care facilities that must comply with extremely stringent regulations. Gravity ventilators are used to equalize a building's positive or negative pressure created by other fans in the system. These ventilators provide natural ventilation and are used for intake and relief applications. Twin City Fan offers both spun aluminum and hooded ventilators, featuring a low silhouette for low roof-lines. Louvered penthouse ventilators are available when aesthetics are not an important factor and feature extruded aluminum louvers. Sidewall exhaust and supply applications require panel fans to move large volumes of air at low static pressures. Panel fans are commonly used on the walls of warehouses and manufacturing facilities to supply outside air or to remove hot or noxious gases in exhaust configurations.  Other typical applications include removing carbon dioxide from produce storage facilities, greenhouse ventilation, and parking garages. Panel fans can be mounted directly to the wall panel, which is especially useful when ductwork is unnecessary. Each fan can be customized to the individual needs of the customer, including aluminum or stainless steel construction, explosion proof motors, gravity or motorized dampers, corrosion resistant coatings, and fully reversible propellers.
