The Fasco B24220 in Short
Fasco B24220 Centrifugal Blower moves 135 CFM, which is enough to exhaust radon from a basement at the lower end of the required range.
Properly ventilated crawlspaces require a consistent 50 to 150 CFM of airflow to prevent moisture buildup and air stagnation. Achieving this requires a blower that maintains steady pressure despite the resistance of a confined space.
The Fasco B24220 Centrifugal Blower meets this need by providing 135 CFM of airflow. It utilizes a sleeve bearing, which is a type of bearing that allows the shaft to rotate within a fitted sleeve to reduce friction.
We selected this model from 8 screened centrifugal blowers because it has 33 buyer ratings, the 4th most of the 8 screened. Our full review is for buyers who need a 115 Volts, 1.3 amps blower for small-scale ventilation.

Before You Buy: Centrifugal Blower Checklist
The first thing to check is the airflow capacity to ensure it meets your specific ventilation needs before you place an order.
- ☐ Confirm the airflow capacity—the Fasco B24220 provides 135 CFM—is sufficient for your space, as a lower flow rate will fail to move air through long runs or restrictive filters.
- ☐ Measure your mounting space—the unit measures 8.8 x 8.6 x 8 inches—to ensure it fits your housing, otherwise you will have to return or modify the mounting hardware.
- ☐ Check your power supply—the blower requires 115 Volts—to avoid electrical installation errors where the voltage does not match your standard household outlet.
- ☐ Verify your duty cycle—the Fasco B24220 uses a sleeve bearing—to prevent bearing seizure if the blower is operated in environments exceeding its rated limits.
- ☐ Budget for the electrical load—the unit draws 1.3 amps—to ensure your circuit can handle the continuous draw without tripping a breaker.
You should not buy this blower if you require whole-home ventilation or laboratory fume hood extraction, as the 135 CFM capacity is not enough for those high-volume applications.
What the Numbers Mean in Use
Sleeve Bearing Reliability
You need to know if the 135 CFM is enough to move the volume of air for your setup. This blower provides 135 CFM, which is sufficient for moving air in a tight crawlspace or for radon exhaust at the lower end of the 100 to 300 CFM requirement. Because airflow capacity measures the volume of air moved per unit of time, this figure determines the maximum space the Fasco B24220 can effectively ventilate.
The Fasco B24220 utilizes a sleeve bearing, a type of support that allows the impeller to rotate within a lubricated sleeve. This design supports consistent operation for standard ventilation tasks but differs from high-pressure industrial blowers that may require specialized heavy-duty bearings. You can rely on this bearing type for steady airflow in environments where the blower operates within its rated duty cycle.
How thermal protection prevents this Centrifugal Blower from overheating
The Fasco B24220 includes thermal protection, which is a safety feature that prevents the motor from overheating. This allows you to operate the unit in enclosed spaces where heat buildup might otherwise occur. By monitoring internal temperatures and cutting power if limits are exceeded, the unit protects the motor from damage during continuous use.
This protection works alongside the UL recognized and CSA or ULc certifications, which indicate the unit meets specific safety standards for its application. These certifications provide a baseline for safety in commercial or industrial settings. You can use the Fasco B24220 in projects where meeting established safety standards is a requirement for the installation.
Compatibility of this Centrifugal Blower with 115V standard outlets
The Fasco B24220 operates on 115 Volts, making it compatible with standard North American electrical outlets. This voltage allows for easy integration into existing building power systems without the need for specialized high-voltage wiring. The 1.3 amps of current draw ensures the unit operates within the capacity of standard circuits.
The 8.8 x 8.6 x 8 inches dimensions allow the blower to fit into restricted spaces where larger industrial-scale centrifugal blowers would be too large. Because the Fasco B24220 weighs 5 pounds, it is manageable for mounting in various locations. You can place this unit in tight configurations while still maintaining the 2600 RPM rotational speed needed for your airflow requirements.
