The nominal rated voltage of the air pump is DC13.5V, and it can operate from 5 to 13.5V in practice. The rated voltage of 13.5V can reach a no-load flow rate of over 4L, and the flow rate can reach over 1.4L under a load of 225mmHg. The 5V test flow rate is also good and the sound is not loud, making it very suitable for modifying the fishing and fish farming air pump, and the lifespan is also better.
The solenoid valve is a normally open bidirectional solenoid valve, but the inflation can only be connected to the positive and negative poles of the power supply. After the solenoid valve is powered on, it will stop inflation. The top of the pump head is also integrated with a vent valve, which can be deflated when the target container is full. It's actually very simple to use. If you do not need to use an electromagnetic valve, you can directly connect the black and red lines marked in the diagram. The red positive and black negative lines are the control lines of the electromagnetic valve. If you want to use an electromagnetic valve, you only need to short circuit the orange and red lines. The working voltage of the electromagnetic valve needs to be above 9V, and the low-voltage electromagnetic valve does not work or the working state is incorrect.
The motor air pump weighs approximately 133 grams. (There are two types of appearance that are basically the same, with different outlet diameters: outer diameter 4.5mm and 3.5mm, shipped randomly)
