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：

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.

How to Use the Blower Correctly

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.

Medical blower control via pneumatic patient model

A medical ventilator, having a blower , is controlled in operational use through a mathematical model of the ventilator-patient combination in order to control the airflow rate via controlling the pressure. Time delay control and iterative learning can be applied in order to improve accuracy of the control.

The invention relates to medical equipment comprising a medical ventilator and a control system for controlling operation of the ventilator in operational use.

Medical ventilators (or: resuscitators) are often based on a system with a ducted mechanical fan, also referred to as a “blower”. The blower used in such medical equipment is an actuator, driven by an electric motor and designed for accurate control of air pressure within a system, e.g., a patient. The desired magnitude of the pressure is a function of the motor speed or duty-cycle of the control signal for the motor. This desired magnitude of the pressure is relatively independent of the system in which the pressure is to be controlled. An example of such a blower is the radial blower also referred to as a centrifugal fan.
