| Blower Performance |
12V dc brushless mini blower can reach maximum 8m3/h airflow at 0 kpa pressure and maximum 4.8 kpa 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 3.5kPa resistance if we set 100% PWM. Other load point performance refer to below P-Q curve:

| How to use the blower correctly: |
This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.
Filter onto the inlet to protect the blower from dust and water.
Keep the environmental temperature as low as possible to make the blower lifetime longer.
This is internal drive and speed controllable version blower, external driver board is not required.
| DC brushless blower advantage |
(1).12V dc brushless mini blower is with brushless motors and NMB ball bearings inside which indicates very long life time
(2).MTTF of this blower can reach more than 20,000 hours at 20 degree C environmental temperature.
(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.
(4).It can be controlled by intelligent machine and equipment easily.
Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.
| FAQ: |
Q: Can you design a new blower fan if we give you target performance?
A: Yes, we offer ODM service for both blower fan and controller board.
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.
