The Airflow Capacity of 353CFM measures the volume of air moved through the system per unit of time.

Before You Buy: Centrifugal Blower Checklist

The first thing to check is your power supply requirements, as this blower requires a 230V source to operate.

• ☐ Confirm your outlet provides 230V—using a lower voltage source will prevent the motor from starting.
• ☐ Verify your space requires 353 CFM—this airflow capacity is sufficient for radon exhaust from a basement but will not provide enough volume for a laboratory fume hood.
• ☐ Check your ductwork resistance—the 1800RPM rotational speed provides the necessary movement, but a static pressure mismatch occurs if the blower lacks the capacity to push air through long runs or restrictive filters.
• ☐ Measure your required airflow—if your project requires more than 353 CFM, this unit will fail to move the necessary volume of air.
• ☐ Verify the operating environment—operating the blower outside its rated duty cycle can lead to bearing seizure, which ends the unit’s service life.

You should not buy this blower if your application requires a flow rate higher than 353 CFM, such as for a high-volume laboratory exhaust system.

What These Specifications Let You Do

How 11.4 m3/min airflow capacity supports radon exhaust and ventilation

When you need to ensure air moves consistently through a large room or a basement, the 353 CFM (11.4 m3/min) airflow capacity of the Ebm-Papst D2E133-AM47-94 AC Centrifugal Blower provides enough volume for radon exhaust or crawlspace ventilation. This volume of air moved per unit of time is sufficient for these specific tasks because they require between 100 and 300 CFM. However, the 353 CFM capacity is not enough to ventilate a laboratory fume hood, which requires at least 400 to 800 CFM.

The D2E133-AM47-94 Blower provides a specific volume of air that supports whole-home ventilation at the lower end of the typical 300 to 600 CFM requirement. Because airflow capacity measures the volume of air moved rather than the force of that air, you should rely on this figure to size your ventilation for open spaces. If your application requires the higher volumes needed for industrial fume hoods, the 353 CFM limit means this model will not meet that specific requirement.

150 Pa Static Pressure Output

Determining if this blower provides enough pressure for your specific ducting layout depends on the resistance of your system, which the 150 Pa static pressure output is designed to overcome. Static pressure measures the resistance the fan must push against, such as through long duct runs or restrictive filters. While 150 Pa is a functional value for many standard configurations, it is important to note that none of the products we evaluated state a figure at the 100 inches of water gauge (w.g.) level, which marks the transition to high-pressure industrial ductwork.

The 150 Pa output allows the D2E133-AM47-94 Blower to maintain airflow even when the path is restricted, ensuring the air does not stall before reaching its destination. You should compare this 150 Pa figure against the total pressure drop of your planned ductwork to ensure the blower can maintain the required velocity. If your layout involves extremely long runs or high-resistance filters, a static pressure mismatch can occur where the fan lacks the capacity to move the required volume of air through the system.
