Notes:
1.Don't use max pressure and working point, this point is not safe since airflow is too small;
2.To add a filter onto the inlet can make the blower run longer time;
3. The right impeller run direction is CCW.
P-Q performance curve:
OWB9070-24V Blower can reach maximum 115L/min airflow at 0 kpa pressure and maximum 13.5kpa static pressure. It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM. It has maximum efficiency when this blower run at 13.5kPa resistance if we set 100% PWM. Other load point performance
DC Brushless Blower Advantages:
(1) OWB9070-24 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 10,000 hours at 20 degree C environmental temperature.
(2) This mini blower needs no maintence
(3) This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration, brake etc.it can be controlled by intelligent machine and equipment easily
(4) Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.
Certificate:
A:Yes, we offer ODM service for both blower fan and controller board
Q2: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.
Q3: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.
Q4: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.
Q5: Can we use this centrifugal air blower to suct water?
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.
Q6: 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.
Q7: 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.
