Draw-Thru Supply Application
(Large Capacity)
A 60-inch, single-width, medium
pressure airfoil centrifugal fan is used
in the system illustrated in Figure F-5 to
supply 45,000 cfm of air. This capacity
can be easily achieved by installing a
pair of 40-inch Model Q™ fans in
parallel as shown in Figure F-6. The
resulting floor space savings is
approximately 85 sq ft!
Blow-Thru Supply Application
Figure F-7 shows a typical medium
pressure, built-up, blow-thru system.
The fan, enclosed in a plenum, is a 33-
inch, double width, airfoil centrifugal
that delivers 30,000 cfm of air. The
bulkiness of the plenum is dictated by
the necessary clearances around the
fan. To save floor space, a 44-inch
Model Q replaces the centrifugal in
Figure F-8. The suspended mounting of
the Model Q frees about 70 sq ft for
installation of pumps and other
equipment.
