7040 DC12V 24V brushless centrifugal blower, dc centrifugal fan with three phase motor and driver controller WM7040-12/24

FEATURES:

1>High pressure (Total pressure 7.5KPa )

2>High airflow (240 L/min)

3>Low noise (30 dBA 1KPa when 1m far.)

4>Long expectancy life (up to 25000hrs if use it in correct way that run for 4 hrs and stop for 30 mins.)

5>Low temperature rise

6>Energy-saving

7>Compact size

8>Environmental-friendly material

9>The motor core adopts coreless motor design that has characteristics of high efficiency, high speed and high stability.  

NOTES:

1> Do not use max pressure as working point, this point is not safe since air flow is too small. 

2> To add a filter onto the inlet can make the blower run longer time.

3> This dc brushless centrifugal fan is controlled by external driver. It can not operate alone without external driver. 

4> When the external driver is connected with power supply, the fan can not be plugged-in.
