INDUSTRIAL PROCESS AND COMMERCIAL VENTILATION SYSTEMS
ATEX (ATmosphères EXplosibles) is a conglomeration of European Union (EU) directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the EU’s ATEX Manufacturer’s Directive (94/9/EC). The ATEX Directive applies to all countries in the EU and the European Economic Area (EEA)

TVIFE Mixed Flow, Induced Flow
The TVIFE is an arrangement 4, direct drive, induced flow fan that utilizes a mixed flow wheel. The TVIFE housing uses an innovative Turbo-Vane™ design that integrates the internal nozzle and straightening vanes into one. Turbo-Vanes™ induce air within the fan housing as well as the windband, giving the best entrainment and efficiency in the industry. The design also allows for uniform motor cooling, while keeping the motor out of the airstream. Sizes are available from 12.5" up to 66" and capable of handling over 80,000 cfm. Twin City Fan & Blower model TVIFE is tested and certified in accordance with AMCA 260 (induced flow) for air and sound.
BAIFE/ BCIFE Centrifugal Induced Flow
The BAIFE utilizes a highly efficient airfoil bladed centrifugal wheel and is tested and certified in accordance with AMCA 260 (induced flow) for air and sound. Available in arrangements 1, 4, 8, 9 and 10. The BCIFE utilizes a backward inclined centrifugal wheel and is intended for high moisture and high temperature applications. The BCIFE is tested in accordance with AMCA 260 (induced flow) for air and sound. Available in arrangements 1, 4, 8, 9 and 10.
QIFE Mixed Flow, Induced Flow
The model QIFE is an arrangement 9 belt driven induced flow fan utilizing a mixed flow wheel. Sizes are available from 12.5" up to 66" and capable of handling over 75,000 CFM. The nozzle on the QIFE has a built-in drain pan to reduce potential rain entry into the building when the fan is not running. Twin City Fan & Blower model QIFE is tested and certified in accordance with AMCA 260 (induced flow) for air and sound.
QFE / TFE Mixed & Inline Centrifugal
The TFE is an arrangement 9 belt driven inline centrifugal fan that utilizes a high velocity discharge nozzle to achieve a high plume height. The TFE offers a gravity damper at the fan outlet for full positive shut-off when the fan is not in use, which prevents rain from entering the building. The QFE is similar in design, but incorporates a high efficiency mixed flow wheel design.
