90mm small sized 7Kpa high pressure dc blower

23000rpm speed 180W BLDC blower are widely used in various medical devices like respiratory ventilators. The reason for their popularity is their ability to provide continuous and consistent airflow with a reliable and robust design. These fans, unlike traditional fans, do not have a mechanical brush that contacts the rotor, resulting in better efficiency and longer life span.

Blower Performance

WS9260B-12-250-S200 blower can reach maximum 120m³/h airflow at 0 kpa pressure and maximum 7kpa static pressure.It has maximum output air power when this blower run at 7kPa resistance if we set 100% PWM, It has maximum efficiency when this blower run at 16kPa resistance if we set 100% PWM.Other load point performance refer to below P-Q curve:

DC brushless blower advantage:

(1)WS9260B-12-250-S200 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 30,000 hours at 20degree C environmental temperature.

(2)This mini blower needs no maintence;

(3)This mini 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.

Applications:

This blower can be widely used onto vacuum machine,fuel cell.

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 life time longer.

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.
