The TKFAN-BA7050 high pressure blower can be adapted to a variety of air cushion machines, the blower has a strong air volume and air pressure performance, and the output air flow can meet the high demand for inflation. The high air volume ensures that enough air can be quickly and evenly filled into the air cushion film, making the saturation of the production film reach more than 90%; The high wind pressure ensures the stability and consistency of the air flow during the inflation.

Through the external customized driver, the speed adjustment and actual speed measurement of the inverter blower can be realized. The yellow line is the Frequency Generator (FG) speed square wave output function lead, and the blue line is the PWM pulse signal input function lead. Users can choose PWM duty ratio speed regulation or 0~5V voltage speed regulation, high flexibility. 0~5V (DC Voltage control) Introduction With this function,the speed can be controlled by applying an extro DC voltage signal. This voltage input"Vin" may have any value from 0V to 5V. Normally two kinds of "speed VS dc voltage curve" are used. PWM (duty cycle control) Introduction With this function,the speed can be controlled by applying a pulse width modulated signal whose frequency maybe in the range of 25k Hz~30k Hz.High voltage means 3~10V.Low voltage means 0~0.8V.Normally two

0~5V (DC Voltage control) Introduction
With this function ,the speed can be controlled by applying a pulse width modulated signal whose frequency maybe in the range of 25k Hz~30k Hz .High voltage means 3~ 10V. Low voltage means 0~0 .8V.Normally two kinds " Speed Vs duty cycle curve " are used.
Fan with FG function will creat a square wave output.You can know fan speed by sensing the output wave Frequency. Most dc fan have four
pole .So when fan run for one round ,there will be one high level pulse .
About other Multipole brushless fan , high level pulse will be different. But please notice if you want to sense it's output wave ,there is a external circuit. Please check the circuit Diagram below. There is no pull-up and VCC value limit. But please notice the Max Iin have to be small than 20mA.
TKFAN high-pressure blower installation in the air cushion machine Photo:
The TKFAN-BA7050 blower device is connected to an external driver in the cavity of the air cushion machine , and runs after being powered on . The speed can be adjusted through PWM .
The following is a video of the air cushion machine with TKFAN high pressure blower at work. Thanks to the high pressure and high airflow performance of the blower, full bubble film can be generated quickly:
