Suited for high-volume airflow in 12 VDC systems

This blower suits installations that need strong airflow at low static pressure. It fits equipment rated for 200 Degrees F ambient temperature. Builders who need higher static pressure performance or a different voltage supply should look at other options.

1555 CFM at 0.000 In. SP defines the airflow

The 1555 CFM rating at zero static pressure is the key figure for sizing this blower. At 0.375 In. SP the output reaches 800 CFM while at 0.500 In. SP it drops to 339 CFM. Match these points to your duct resistance to confirm the right part.

Questions about this item

What power source do I need to run this 12 VDC blower?

The fan operates on a 12 V DC supply and draws 3/32 hp from the motor, so a compatible 12-volt DC power source rated for that load is required.

Will the 14-inch blade diameter and 2600–3200 RPM range fit my existing duct opening and mounting points?

The blower uses a 14 in blade diameter with a totally enclosed DC motor running at 2600 to 3200 RPM; verify your duct and bracket dimensions against those specifications.

How can I confirm the blower is delivering the rated airflow after installation?

Measure the output against the published CFM curve: 1555 cfm at 0.000 in. SP, 1400 cfm at 0.125 in. SP, 1200 cfm at 0.250 in. SP, 800 cfm at 0.375 in. SP and 339 cfm at 0.500 in. SP.
