TROX TMFT and FT series fan terminals are designedspecifically for application in underfloor air distribution systems. Their low profile design allows their installation in finished floor installations as low as twelve (12) inches. Their small footprint assures their fit within the access floor support structure and allows most maintenance to be performed by the removal of a single floor tile. TROX underfloor fan terminals are also engineered forpressurized floor supply applications. TROX is the world leader in underfloor air distribution and, as such, understands and designs around the differences between pressurized floor cavity supply and the ducted delivery typically employed by overhead air distribution systems. These terminals are designed to operate at the highest energy efficiency possible in order to support sustainable buildingpractices and preserve the environment.

Raised access flooring systems are usually employed due to their superior management of power, voice and data cables that service the office space. The same cavity that houses these services can be used as a supply air plenum to extend the space service delivery of the access floor platform to mechanical systems as well. However, every effort should beexerted to assure that the HVAC system is as compact and simple as possible as minimal disturbance to the floor cavity is the key to a successful raised floor service platform. TROX underfloor fan terminals are designed to minimize ductwork and plenum partitions within the floor cavity while, in combination with TROX FB series high induction floor diffusers, providing space occupants comfort, controland air quality levels unparalleled by any other conditioned air delivery system.

Product Features

FT SERIES TERMINAL FEATURES
FTC, FTV, FTU, FTG, FTR and FTD Models

High efficiency PSC motors allow highest airflow to horsepower ratio available. Electronically controlled variable speed motors are also available.

Unique sealing tubes allow terminals to integrate with access floorsupport system (not necessary for size 300 and 600 models).

Hot water coils (applicable models) have unique protective angle.

Aluminum opposed blade damper with airfoil blades used for all inlet and VAV dampers (on applicable models).

Factory balanced forward curved fan wheels for maximum efficiency.

TMFT SERIES TERMINAL FEATURES
TMFT-C and TMFT-E Models

TMFT terminals discharge airthrough two FB series diffusers mounted in the floor tile directly above, eliminating the need for any inlet or outlet ductwork.

TMFT-C models incorporate a shut-off damper to prevent flow through the terminal during unoccupied periods. TMFT-E models incorporate an electric reheat coil for perimeter office and conference area applications. Double blower configuration operates at low RPM tominimize noise generation.

TMFT terminals are furnished with four (4) leveling feet which can be field adjusted for mounting in any floor cavity depth up to 18 inches.
