Belt and Direct Drive In-Line Centrifugals
Models XB and XD
Models XD and XB are square in-line centrifugal fans designed
to eliminate costly round to square ductwork transitions with the
flexibility of any angle operation. XD is direct driven and XB is
belt driven. Model XD is available in five sizes with capacities
up to 5445 CFM and up to 1 3/4” static pressure. Model XB is
available in eight sizes with capacities up to 28,332 CFM and up
to 2 1/2” static pressure. AMCA “B”
spark resistant construction is
standard on both models. The XD
is suitable for airstream
temperatures up to 140°F and the
XB up to 200°F.

Performance certified is for Installation Type A: Free Inlet, Free Outlet. Performance ratings do not include the effects of appurtenances (accessories).
The sound ratings shown are loudness values in hemispherical sones at 1.5 m (5ft) in a hemispherical free field calculated per AMCA Standard 301. Values are
shown are for Installation Type A: Free Inlet hemispherical sone levels.
Power rating (BHP) does not include transmission losses. The brake horsepower capability of an exhauster motor is dependent on the degree of cooling the motor
receives from the air moving through the motor. The above motor loadings do not overheat the motor and are in accordance with the motor manufacturer 's
recommendations. It is, therefore, not detrimental to the motor and economically desirable. Maximum RPM shown obtained with the standard one speed motor; for
all other RPM's add solid state speed controller. Performance is based on actual speed of test.
