Tubular Centrifugal Fans Model TCB Inline - Horizontal or Vertical Roof Upblast and Roof Supply

Tubular Centrifugal Fans TCB series of inline centrifugal fans are designed for ducted inline, roof upblast, and roof supply installations. Whether the application is commercial or industrial, Greenheck tubular centrifugal fans provide quiet, efficient, and reliable air performance. All TCB products are belt driven with motors out of the airstream. Housings are constructed of welded steel or aluminum (optional) and are suitable for indoor or outdoor applications. The backward inclined wheels are manufactured from aluminum and are suitable for clean air or fume exhaust applications. All TCB products...

Two Levels of Construction All TCB inline and roof mounted fans are available in two levels of construction to provide the most efficient and economical selections. Construction differences between level 1 and 2 selections include the impeller, the inlet cone, the shaft size, and the bearings. The housings for both levels are identical in material gauge and overall design. Maximum pressure capabilities of 2 in. wg (500 Pa) Highest efficiencies at static pressures below 1.5 in. wg (375 Pa) Aluminum wheel construction Most economical selections Maximum pressure capabilities of 4.5 in. wg (1,125...

TCB Inline Fan - Belt Drive The Model TCB inline fan is the ideal choice for ducted systems. Greenheck’s standard fan can be mounted in any position from horizontal to vertical, allowing installation in the smallest possible space at the lowest installation cost. The centrifugal wheels used in this design provide higher efficiencies and lower sound levels than propeller type inline fans when used in medium pressure ducted systems. TCB fans are available in either painted steel or aluminum construction. Typical applications include: • • • • • • General exhaust or supply Industrial space ventilation...

System Effect Curves The TCBRU is ideal for roof upblast exhaust systems with moderate system static pressures and for applications where quiet operation is essential. Standard features include a necked-down windband section which creates the high outlet velocities necessary to carry contaminated exhausts away from the roof deck. All TCBRU fans include motor covers for weather protection of the motor and drives, gravity operated dampers to prevent backflow into the building, and a welded curb cap for ease in mounting to a roof curb. TCBRU fans are available in either painted steel or aluminum...

TCBRS Roof Supply Fan The TCBRS roof mounted supply fan is designed for intake air systems with pressures up to 4 inches of wg and where low sound is required. The TCBRS hood intake is located at a sufficient height above the roof to limit entry of roof debris and snow. In addition, the hood has sufficient intake area to keep velocities low. Filters are available to collect dust and moisture before entering the building. Motor and drive protection is provided with a weatherproof motor cover. For ease of installation, TCBRS fans are shipped assembled and have curb caps for attaching to roof curbs....

Optional Construction for UL 762 Restaurant Exhaust Inline grease exhaust fans are excellent alternative for kitchen applications when roof or wall mounted ventilators are not practical. The TCB with UL 762 grease option is designed to withstand the demands of high temperature kitchen grease exhaust and high-pressure duct washes. Leak Resistant Construction Features 1 Continuously welded housing and integral duct flanges provide air and water tight design. 2 Bearing cover gasketed and includes a labyrinth shaft seal to prevent moisture leakage during normal operation and while cleaning with high...

Belt Guard (TCB only) Belt guards are totally enclosed to provide protection from rotating pulleys and belts. Belt guards meet OSHA guidelines. Motor Cover (Weatherhood) Weatherproof motor covers shield the motor and drive components from dust, dirt and moisture when used in outdoor applications. Motor covers also provide protection from rotating pulleys and belts and meet OSHA guidelines. Motor covers are standard on TCBRU and TCBRS models. Inlet and Outlet Companion Flanges (TCB only) Companion inlet flanges and outlet flanges with prepunched holes are available for all fan sizes in painted...
