Tubular Centrifugal Fans
The TCB series of inline centrifugal fans is 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 meet
“Type B” construction as defined by AMCA Standard 99-0401 Classification for Spark Resistant Construction. In
addition, the TCB is available with the UL 762 listing for restaurant exhaust applications.
Greenheck Fan Corporation certifies that the model
TCB tubular centrifugal inline fans shown herein
are licensed to bear the AMCA seal. The ratings
shown are based on tests and procedures performed
in accordance with AMCA Publication 211 and
Publication 311 and comply with the requirements of
the AMCA Certified Ratings Program.

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
• Fume hood exhaust (special coatings are available)
• Combustion air
• Roof exhaust or supply (with weatherhood)
• Restaurant grease exhaust
Universal Mounting
All TCB fans can be mounted horizontally or vertically. For
ease of installation, eight mounting brackets are welded
on each fan. The eight brackets along with four mounting
supports, provide a universal mounting system.
Fig. 1 Horizontal Base Mount
Each fan is shipped as standard in this arrangement.
Motor at 12 o’clock is standard.
Fig. 2 Horizontal Base Mount with Motor at

A set of optional mounting rails are required for this
installation. This is the base mounting position required with
the easy access option.

TCBRU Roof Upblast Fan
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 construction.
Typical applications include:
• Low cfm/high velocity exhaust
• General exhaust
• Fume hood exhaust
• Industrial process exhaust
When selecting TCBRU fans, use the TCB inline performance data
(pgs. 12 to 31) along with the following system effect curves. The
pressure loss determined below must be added to the extended
system static pressure to assure accurate selections. Greenheck’s
Computer Aided Product Selection (CAPS) software will add these

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. TCBRS fans are available in either
painted steel or aluminum construction.
Typical applications include:
• Ducted supply systems
• Industrial space supply
• Filtered supply

Aluminum units are uncoated.
Type B Spark Resistance
All fans have aluminum wheels and a nonferrous
(aluminum) rub ring which surrounds the fan
shaft where it passes through the drive cover.
This construction meets Type B spark resistant
requirements.
Belts, bearings, and drives are protected from the
airstream by heavy gauge belt tubes and bolted
bearing covers with shaft seals.
Extended

Lubrication lines with grease
fittings allow bearing lubrication
without disassembling the fan.
Optional Construction Features
Aluminum Construction
Aluminum construction is available on the TCB, TCBRU and TCBRS. Aluminum fans are an excellent choice for
applications involving moisture or coastal installations.
Easy Access Construction
The Easy Access option is highly recommended to allow for
inspection, cleaning and service of internal fan components.
By removing one access panel, service to the wheel, shaft,
and bearing assembly is possible without removing duct
connections. In addition, all internal fan components can be
removed from the fan through the easy access panel.
Easy Access construction is available on all levels and sizes
of TCB, TCBRU, and TCBRS. Easy Access is also available
with aluminum fan construction.
Note: The Easy Access panel is located 180° from the motor
position.

System Design Guidelines
• Inline grease exhaust fans should be installed near the end of the duct run to reduce sound at the hood.
• Inline fan must be securely bolted to the exhaust duct per NFPA-96 guidelines. Greenheck’s companion flanges
are recommended for ease of installation.
• Grease exhaust fans and ductwork must maintain 18 inches (46 cm) minimum clearance to combustible
material. If the ductwork and fan are insulated, the inspection door must be accessible for maintenance.
• A minimum of 10 ft. (3.0 m) of clearance must be kept from the fan outlet to adjacent buildings, property lines,
or the closest point of any air intake or operable window at or below the plane of the exhaust termination.
• Greenheck recommends that all inline grease applications be reviewed by your local code official to ensure
compliance with NFPA, IMC, and other local codes.
UL 762 is concerned with fans
designed for removal of smoke and
grease laden vapors with airstream
temperatures up to 300°F.
