Features
and Benefits
The Trane Model Q ™ and Super Q II
fans can help you maximize your
building’s usable floor space by using
them in place of centrifugal fans. The
smaller the equipment room, the more
space left for tenants, merchandise, etc.
Saving Valuable
Equipment Room Space
Return or Exhaust Applications
Figure F-1 shows a size 44, single
width, low pressure airfoil centrifugal
fan delivering 20,000 cfm of air.
Because of its size and weight, it is floor
mounted and connected to a return air
plenum. In contrast, a 44-inch Model Q
fan is used in Figure F-2 instead of a
centrifugal fan. Its smaller size and
lighter weight permits ceiling
suspension and approximately 75 sq ft
of floor space is freed up for other use. Draw-Thru Supply Application
(Small Capacity)
The fan system in Figure F-3 is a
27-inch, single width, medium pressure
airfoil centrifugal fan rated at 9,000 cfm.
Even though it is a relatively small fan,
it is floor mounted beside the coil bank
plenum. Figure F-4 shows a 27-inch
Model Q substituted in place of the
centrifugal. The small size and weight,
plus the installation flexibility of the
Model Q, permits mounting in a
vertical position on top of the plenum.
The space savings is about 25 sq ft.
