Will the Fasco B47120 fit in a space of 13 inches?

You must verify your mounting area has at least 13 inches of clearance and identify the exact placement for the centrifugal housing—a circular metal casing that pulls air in and pushes it out—before ordering.

Fasco B47120 dimensions and installation requirements for 13-inch spaces

The Fasco B47120 features a 12.8 x 11.7 x 5.7 inch footprint, providing a small buffer for a 13-inch constraint. Because centrifugal blowers often require ductwork (pipes that channel air to a destination) for proper flow, you should confirm your installation allows for these connections beyond the 12.8-inch housing width. We selected this model for our comparison because of its 180 CFM airflow capacity and three-speed motor options. Will the motor housing depth interfere with your enclosure? The depth of this unit is 5.7 inches, which typically allows for a shallow recessed fit if the intake and exhaust are clear.

What to Check Before Buying the Fasco B47120

Centrifugal blowers require precise spatial planning because the housing and connected piping must not be compressed, which can restrict airflow or cause the motor to overheat. Check these points before purchasing:

For a final summary, see the Fasco B47120 final verdict.

• Confirm your mounting surface can accommodate the 12.8-inch maximum width.
• Measure the clearance needed for ductwork connections on both the inlet and outlet sides.
• Verify if your space requires vibration isolators, which are mounts that reduce noise and movement, as these add to the total width and depth.
• Check if your local electrical setup supports 115 Volts and 1.95 Amps.

Comparing the Fasco B47120 to Other Options

The Fasco B47120 serves users who need a compact, 115V blower with reliable 180 CFM performance. If you require a higher static pressure to move air through very long, restrictive runs, or if you need a variable frequency drive for precise flow control, you may want to look at industrial-scale centrifugal blowers. These larger units provide more power but often exceed the dimensions of this specific model.

If you are on a budget, view the best centrifugal blower under $300.

If you need a blower that fits within a tight 13-inch clearance and requires a standard 115V connection, choose the Fasco B47120.
