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 3 or 9 o’clock

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

Fig. 3 Horizontal Ceiling Hung

In this installation the supports can be positioned for mounting the motor at either 6 or 12 o’clock.

Fig. 4 Horizontal Ceiling Hung with Motor at 3 or 9 o’clock

A set of optional mounting rails are required for this installation.

Fig. 5 Vertical Mount

All TCB fans can be mounted vertically (ceiling hung or base mount) for either upward or downward airflow. Optional mounting rails are recommended.

NOTE:

All fans are shown with optional vibration isolators. See the appropriate submittal drawings or installation manual for complete dimensional data.

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)

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 system effects automatically.

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.
