Duct Connections
Supply Air
For connection of supply ductwork directly to the unit, a
duct collar must first be mounted at the fan outlet, avoiding
the mounting screws located around the perimeter of the fan
discharge opening. Fan discharge opening sizes are indicated
on the unit dimensional drawings. When connecting duct-
work to the unit, use a canvas type connecting collar. To
maintain specified fan performance, two-fan units should
incorporate a properly designed "pants" duct connection
(refer to Figure 10).
Units are available in two fan configurations as shown in
Figure 11. Duct take-offs which go opposite to the direction
of fan rotation will result in an associated system effect loss
and reduced fan performance.
