TBI Tubular Belt Inline Fan
TDI Tubular Direct Inline Fan
RECEIVING
Greenheck model TBI / TDI fans are thoroughly inspected and test run at the factory. Items such as proper propeller
alignment, balance, and workmanship are analyzed by personnel using state-of-the art equipment. However, damage may
occur during handling and shipping. Therefore, it is important that the unit be carefully inspected for visible and concealed
damage before beginning installation. In addition, check to see that all accessory items are accounted for.
STORAGE - Indoor and Outdoor
When a fan is to be stored for a period of time, it must be protected from dirt and moisture. Use of a tarp to cover the unit
will aid in keeping it clean and dry, but avoid using a black plastic tarp as it will promote condensation. Improper storage
which results in damage to the fan will void the warranty. If the storage period is lengthy, the propeller and motor should be
rotated periodically and the bearings purged with fresh grease. In humid, dusty, or corrosive atmospheres, rotate the fan and
purge the bearings once a month. Under normal conditions, this procedure should be repeated once every three months.

HANDLING
Fans should NOT be lifted by the shaft, housing, motor, belt guard, or any
accessories.
Units - Flanged Housing Only
Use a minimum of four bolt holes, two per flange, or attach two suitable chains /
straps around the entire fan housing, one near each duct flange, when lifting large
horizontal fans. Secure the fan housing to prevent the weight of a top or side
mounted motor from rotating the housing while being lifted.
For vertical hanging installations, attach a suitable lifting device to the fan housing or
inlet/outlet flange.
Units - With Mounting Brackets
Fans are to be rigged by either the optional brackets provided or by the skid when a
forklift is used. Slings can be attached as described above or to mounting brackets
located at the ends of the fan housing (Fig. 1).

INSTALLATION
EFFECT OF INSTALLATION ON PERFORMANCE
Any installation with inlet or discharge configurations that deviate from these recommendations may result in reduced fan
performance. Restricted or unstable flow at the fan inlet can cause pre-rotation of incoming air or uneven loading of the fan
prop yielding large system losses and increased sound levels. Free discharge or turbulent flow in the discharge ductwork
will also result in system effect losses.
The most common inlet and discharge conditions which affect fan performance are:
INLET DUCT TURNS
Installation of a duct turn or elbow too close to the fan inlet
reduces fan performance because air is loaded unevenly into
the fan prop. To achieve full fan performance there should
be at least one to two fan prop diameters between the turn
or elbow and the fan inlet.
DISCHARGE DUCT TURNS
Fan performance is reduced when duct turns are made
immediately off the fan discharge. To achieve cataloged
fan performance, there should be at least one equivalent
duct diameter of straight ductwork between the fan
discharge and any duct turns.
Motor at 3 or 9 o’clock position
TYPICAL INSTALLATIONS - WITH MOUNTING BRACKETS
Following are typical mounting installations for models with mounting brackets. Diagrams show dimensions for ceiling hung
installations, the dimensions for floor or base mount installations are mirror images of these. For TBI's with motor in the 3 or
9 o'clock position or vertical installations, additional mounting rails are recommended. Mounting rail dimensions are shown
for field fabrication.
