FAQ:
Q: Can we connect this centrifugal air blower directly onto power source?
A: This blower fan is with BLDC motor inside and it needs a controller board to run.
Q: What kind of power source shall we use to drive this blower fan?
A: Generally, our customers use 24vdc switching power supply or Li-on battery.
Q: Do you also sell controller board for this blower fan?
A: Yes, we can supply adapted controller board for this blower fan.
Q: How to change impeller speed if we use your controller board?
A: You can use 0~5v or PWM to change speed. Our standard controller board is also with a
potentiometer to change speed conveniently.
Q: What is the MTTF of this centrifugal air blower?
A: MTTF of this centrifugal air blower is 20,000+ hours under 25 C degree.
Q: Can we use this centrifugal air blower to suct water?
A: This blower fan can not be used to suck water. If you need to suck water, you can ask us to
choose proper item for this special working condition.
Q: Can we use this centrifugal air blower to suck dust directly?
A: This blower fan can not be used to suck dust directly.If you need to suck dust, you can ask
us to choose proper item for this special working condition.
Q: What can do if the working condition is dirty?
A: A filter is strongly recommended to assemble onto the the inlet of the blower fan
Q: How to decrease the noise of the blower?
A: Many of our customers use foam, silicone to fill between blower fan and machine to insulate
the blower noise.
